Sustainable historic-town conservation requires preserving historical patterns and cultural memory while understanding how spatial environments shape everyday perception. Using Yun’an Ancient Salt Town in Chongqing, China, this study develops a three-layer framework of spatial topology, scene interfaces, and historical semantic elements. Space syntax, deep-learning image recognition, rule-based coding, image-based questionnaires, Spearman correlation, random forest regression, and SHAP were used to examine perceived historicity, safety, attractiveness, and comfort. The analysis combined axial models for 1985, 2004, and 2024 with 140 images—55 human view and 85 aerial view—each evaluated by 264 valid respondents. Yun’an’s street network shifted from a salt-production and transport structure toward modern traffic corridors; integration declined in the historic core, and intelligibility fell from 0.13 in 2004 to 0.07 in 2024. At the human-view scale, modern interference was negatively associated with historicity and attractiveness, whereas stairs, traditional components, and micro-historical objects were positively associated with historicity. At the aerial-view scale, historical visibility, character integrity, and blue-green-space indicators were associated with historicity, attractiveness, and comfort. Cross-validated random forest performance was strongest for aerial-view historicity and limited for other outcomes. The findings support a human-centered, culturally sustainable renewal pathway linking historical-street continuity, townscape integration, blue-green quality, and heritage-node activation.

Cultural Routes have become important instruments for promoting shared heritage and sustainable tourism across Europe, yet the potential of travel literature to inform their development remains underexplored, particularly in the case of Via Egnatia. This study addresses this gap by developing a theoretical distinction between travel narratives as ideologically situated representations, shaped by colonial and Orientalist discourse, and as potentially corroborable sources of historical–geographical evidence. It applies this framework to nineteenth- and early-twentieth-century accounts by Byron, Leake, Lear, and Durham, published between 1812 and 1909. Using a qualitative, theory-informed case-study design, the study combines critical discourse analysis with the thematic coding of 127 narrative references, supported by a documented codebook, an intra-coder consistency check (84% agreement), and triangulation across authors and independent historical and archaeological sources. The analysis identifies documentary support for a mobility corridor along the Shkumbin Valley, derived primarily from the convergence between Leake and Lear and consistent with independent archaeological scholarship. A site-level cross-check of six heritage assets and a small purposive sample of recent visitor reviews provides preliminary indications that formal heritage protection already exists along the corridor, while visitor-facing interpretation does not consistently connect individual sites to a coherent Via Egnatia narrative. A similar pattern emerges from the analysis of Albania’s national tourism-planning documents. The study’s principal contribution is theoretical: it shows how critically read travel narratives can extend destination-storytelling and heritage-interpretation theory beyond descriptive associations, while offering a potentially transferable methodological framework for translating narrative and empirical evidence into interpretive practice for the Council of Europe Cultural Routes Programme.

Urban–rural governance and planning systems, as viewed through the lens of online public attention, are reshaping approaches to achieving coordinated development of cultural heritage conservation and urban space. Taking Nanchang as a case study, this paper investigates the application mechanism of online public attention in the evaluation of heritage corridor nodes and the formulation of optimization strategies. Employing multi-source data collection, we extracted textual content from online travelogues. We quantified the online attention level of each cultural heritage unit and analyzed its spatial distribution using kernel density estimation and standard deviational ellipse methods. We then applied a minimum resistance model, incorporating geographic data on land use and transportation networks, to identify potential heritage corridor routes. Based on attention classification, we propose a three-tier optimization strategy: core-leading, marginal-activating, and gradient-linking. Specifically, high-attention heritage units are positioned as central nodes that reinforce corridor connectivity; low-attention nodes are targeted for activation through corridor links to overcome spatial isolation; and attention gradients serve as the basis for hierarchical integration across the network. Our results reveal a pronounced spatial pattern of “core agglomeration and peripheral dispersion” in Nanchang’s heritage corridors. High-attention resources are heavily concentrated in the historic urban core, anchoring the main corridor axes, whereas low-attention resources are scattered across peripheral counties, exhibiting a clear urban–rural attention gradient. Importantly, attention levels show a positive correlation with corridor hierarchy. These findings provide a novel perspective for heritage corridor spatial planning and offer practical insights for sustainable cultural heritage governance and culture–tourism integration in an era of pervasive internet and urban expansion.

Great Wall villages are living cultural landscapes within a linear heritage corridor, yet they face growing pressures from population decline, rural hollowing, uneven development, and tourism-related transformation. This study evaluates the cultural landscape resilience of 20 Great Wall villages in Chicheng County, China. A Cultural Landscape Resilience Index (CLRI) was constructed from three dimensions: resistance, recovery, and learning capacity. The AHP-CRITIC method was used to determine indicator weights, while spatial autocorrelation analysis, principal component analysis (PCA), and multiscale geographically weighted regression (MGWR) were applied to identify the spatial pattern of CLRI and the multiscale effects of its influencing factors. The results show that CLRI was generally low and spatially uneven. Villages with relatively high resilience were mainly concentrated near the county seat and major transportation corridors, whereas many villages along the Great Wall corridor showed lower resilience levels. MGWR results revealed clear spatial heterogeneity in the influencing factors. Heritage revitalization and social development features, heritage preservation and protection, tourism development and utilization, and village patterns and collaborative heritage protection were positively associated with CLRI. In contrast, the diversity of rural village landscapes and the strength of the human-land relationship showed negative associations with CLRI. Heritage revitalization and social development features and rural village landscape diversity operated at relatively broad spatial scales, whereas heritage preservation and protection and tourism development and utilization exhibited stronger local variation. The findings demonstrate that improving the resilience of Great Wall village cultural landscapes requires spatially differentiated conservation and development strategies, including strengthened heritage protection, coordinated conservation of village patterns and heritage elements, context-sensitive tourism development, and improved public services and development opportunities in less resilient villages.

Traditional villages in river basins preserve rural landscapes through both environmental adaptation and accumulated heritage governance. Taking 173 national-level traditional villages in the Fenhe River Basin as the study objects, this study examines their spatial patterns and the heterogeneity of influencing factors using kernel density estimation, nearest-neighbor analysis, spatial autocorrelation, optimal-parameters-based geographical detector, and multiscale geographically weighted regression. The villages display a significant clustered distribution rather than a random or administratively bounded pattern, forming a belt-like structure along the Fenhe River, its major tributaries, and mountain-basin transition zones, with high-density cores in the Taiyuan and Linfen basins. Among all examined factors, the enrichment of cultural relic protection units shows the strongest explanatory power in the OPGD results, with a q-value of 0.4349. Its MGWR coefficients are also predominantly positive and significant, suggesting that officially recognized heritage resources act as spatial anchors for the persistence and organization of traditional villages. Precipitation, elevation, intangible cultural heritage, per capita Gross Domestic Product (GDP), and historical post-road accessibility further shape village density, but their effects are spatially uneven. These findings suggest that conservation in the Fenhe River Basin should move beyond isolated village repair toward a watershed-scale linear heritage network linking river corridors, historical routes, cultural relic protection units, and cross-county governance.

Microplastic contamination is an emerging global concern, but its occurrence in high-altitude protected areas has been understudied. This study systematically assessed microplastic abundance, morphology, and spatial distribution in Sagarmatha National Park (SNP), Nepal, a UNESCO World Heritage Site. Soil samples were collected from 25 sites across four land-use types, including settlement, farmland, forest, and floodplain, at two depths along the Lukla–Phortse trekking corridor during the pre-monsoon season of 2023. Samples were pretreated by density separation and Fenton’s reagent digestion, and microplastics were then detected using a YOLOv11n-seg instance segmentation model. A subset of extracted particles was chemically confirmed by optical photothermal infrared (O-PTIR) spectroscopy. Microplastics were present in all samples, with concentrations ranging from 80 to 960 particles·kg⁻¹. Fragments were the dominant morphological type, accounting for 65.7% of all particles, followed by fibers and films. Negative binomial regression revealed significant effects of land use and soil depth and their interaction on microplastic abundance. Settlement soils showed the highest concentrations with significant surface enrichment, while farmland soils showed no significant depth effect, consistent with human-dominated plastic sources and tillage-driven redistribution. Elevation was not a significant predictor of contamination. Hotspot analysis identified statistically significant clustering around Lukla and Namche, the two primary tourism hubs. The baseline established in this study provides a foundation for long-term monitoring and targeted waste management in SNP and offers insights to other protected high-altitude environments. Meanwhile, the application of deep learning and O-PTIR to balance the counting efficiency and accuracy is a novel approach that could be adopted by other researchers. Full article

Conservation units for traditional village clusters are often delineated by administrative boundaries or spatial proximity. Yet rural built heritage is shaped by historical routes, terrain conditions, cultural homology, settlement morphology, and rural landscape settings. This mismatch is especially evident in mountainous regions, where conservation relevance does not necessarily follow planar distance. To address this issue, this study proposes relational contiguity as an operational concept for cluster-based conservation of traditional village heritage. Using 61 nationally recognized traditional villages in Gaoping City, Shanxi Province, China, as a case, we develop a socio-spatial network framework. The framework integrates composite node quality, cultural homology, MCR-based cost distance, inter-village association strength, and node-role differentiation into a modified spatial interaction model. This allows conservation relations to be identified as culturally meaningful, spatially plausible, and governance-relevant. The results show that only 167 of 1830 village pairs form effective links. This selective heritage conservation network is structured by the Dan River corridor, historical trade routes, high-value heritage nodes, and culturally homologous village groups. Four differentiated conservation units are identified: the fortified landscape conservation unit, the Dan River trade-corridor coordination unit, the landscape-ritual continuity unit, and the peripheral authenticity conservation unit. The study provides a planning support framework for translating inter-village heritage relations into coordinated conservation units for rural built heritage. Full article

This study examines 4811 immovable cultural heritage sites in Mianyang City to address how these sites are spatially clustered, how their distribution varies across historical periods and heritage types, and how the observed spatial patterns are associated with selected natural-environmental conditions. The main objective is to identify the spatial distribution, spatiotemporal evolution, and site-selection characteristics of immovable cultural heritage sites in Mianyang and to provide an environmental and spatial basis for heritage conservation and territorial management. Using ArcGIS-based spatial analysis, this study applies average nearest neighbor analysis, kernel density estimation, standard deviational ellipse analysis, mean center analysis, spatial overlay statistics, and GeoDetector. The explanatory analysis focuses on three natural-environmental variables: elevation, slope, and distance to rivers. The results show that: (1) The sites are widely distributed and exhibit multi-core clustering, with dense concentrations in the south and central-east and sparse distribution in the northwest; (2) their spatiotemporal evolution follows an alternating “agglomeration–diffusion–re-agglomeration” pattern, with the centroid shifting along the middle and lower Fujiang River valley; and (3) the sites are mainly concentrated in low-elevation, gently sloping, water-adjacent river-valley plains and shallow hilly terraces. These findings provide a partial environmental interpretation of the spatial distribution of immovable cultural heritage sites in Mianyang and offer exploratory evidence for identifying priority conservation areas, supporting conceptual heritage-corridor planning, and promoting sustainable heritage management. The study also suggests that future research should further integrate historical transportation networks, administrative centers, population migration, economic activities, religious landscapes, and military-political contexts to explain the broader cultural landscape processes behind heritage distribution.

Fragmented point-based conservation limits the integrated protection and adaptive reuse of timber arch covered bridges. This study develops a quantitative decision-support workflow for identifying and evaluating heritage corridor networks, using 99 timber arch covered bridges in Northeastern Fujian, China, as the regional sample and three representative bridges for bridge-scale interpretation. The workflow combines spatial pattern analysis, Maximum Entropy (MaxEnt) suitability modeling, XGBoost–SHAP-assisted resistance analysis, circuit theory corridor extraction, complex network analysis, and maturity assessment. The results show that the bridges form a significant clustered pattern with a Shouning primary core and a Pingnan secondary core. MaxEnt identified high-suitability areas of 1.857 × 10⁵ ha, accounting for 3.65% of the study area, mainly in the Shouning–Pingnan–Zhenghe border zone. The XGBoost–SHAP procedure was used as a secondary modeling step to translate suitability patterns into a composite resistance surface; it indicated that road proximity, elevation, nighttime light intensity, and distance to points of interest (POIs) were the main variables shaping the model output. Based on 27 selected heritage source sites, 75 primary corridors totaling 4078.22 km were identified, together with 33 pinch points and 27 barrier points. A corridor protection width of 7 km was determined as optimal. Network analysis identified Luanfeng Bridge, Longtan Bridge, and Denglong Bridge as important structural nodes and divided all 99 bridges into five river basin-related communities. Maturity assessment revealed a pattern of “one core, two belts, and multiple nodes” but also considerable functional disparity. The three representative cases are reframed as preliminary interpretations of model results: Luanfeng Bridge emphasizes landscape-integrity and visitor-pressure assessment, Denglong Bridge emphasizes route continuity and low-intervention interpretation, and Qiancheng Bridge emphasizes livelihood coordination and incremental rural tourism. This study provides decision-making support for advancing the integrated conservation of timber arch covered bridges and the synergistic development of rural tourism. Full article

Traditional villages and intangible cultural heritage (ICH) are interrelated components of rural heritage landscapes, linking material spatial carriers with living cultural practices. Yet their spatial matching, mismatch-formation mechanisms, and translation into collaborative conservation zoning remain insufficiently understood. Taking Anhui Province, China, a north–south transitional region, this study examines 836 traditional villages and 685 ICH items at or above the provincial level. We develop a stepwise spatial diagnostic framework that connects clustering identification, positional and quantity–structure mismatch diagnosis, corridor and multi-factor association interpretation, and strategy-oriented conservation zoning. The results show that traditional villages form a strong southern Anhui core (83.01%), whereas the officially attributed locations of listed ICH items are more widely distributed across southern, central, and northern Anhui (43.21%, 26.42%, and 30.36%). The provincial centroid mismatch distance reaches 160.15 km, and prefecture-level cities are classified into ICH-advantaged, traditional-village-advantaged, and relatively matched types. Huangshan further demonstrates that positional proximity does not necessarily imply quantity-structure matching. Mechanism analysis suggests two scale-dependent association patterns: an environmental preservation pattern for traditional villages and a social-transmission and institutional-attribution pattern for listed ICH items. Based on this provincial-scale diagnosis, the study delineates key, secondary, and general conservation zones as strategy-oriented diagnostic zones and proposes differentiated collaborative conservation strategy orientations.

Public space vitality is increasingly regarded as a central issue in the conservation and renewal of traditional villages, yet existing studies rarely combine spatial pattern analysis with residents’ perceptual evaluation within a single framework. Taking Yutu Village in southeastern Hubei, China, as a case, this study develops a Space–Event analytical framework integrating GIS-based spatial statistics with Importance–Performance Analysis (IPA). Semi-structured interviews, participatory mapping, and questionnaire surveys identified 58 public event units, 34 physical public spaces, and 241 event–space coordinate points. Kernel density estimation (KDE) and Ripley’s K-function analysis indicate a composite structure of one core, multiple centers, four axes, and five clusters. Historical and cultural events cluster around heritage buildings, daily life and production events extend along everyday movement corridors up to 155 m, and ritual and folk cultural events remain concentrated at small-scale ceremonial nodes. Based on 112 valid questionnaires, IPA-based evaluation shows negative gaps between importance and satisfaction across all 23 indicators (p < 0.001 for all items), with spatial narrative showing the largest gap (Δ = −1.66), while ritual-related indicators achieve the highest satisfaction scores, suggesting a degree of cultural resilience in ceremonial spaces. By cross-referencing spatial clustering types with IPA quadrants, the study proposes differentiated strategies, including narrative-oriented design for heritage spaces, connectivity enhancement for everyday networks, and protective maintenance for ritual nodes, offering an evidence-based framework transferable to comparable traditional village contexts.

Long-standing studies of historical cultural spaces have primarily focused on the preservation of heritage objects and landscapes, while insufficient attention has been paid to the structural relationships, land-use transformations, and cultural–ecological processes that sustain their long-term continuity. Taking the World Heritage site of Lijiang as a case, this study develops a three-dimensional structural decoding framework composed of spatial base, spatial network, and spatial entity, together with an analytical pathway of “Identification–Interpretation–Evaluation–Synthesis–Practice.” By integrating qualitative and quantitative approaches with multi-source data, the study establishes an evidence chain linking historical processes and contemporary conditions to examine the formation mechanisms, continuity, and contemporary deviations of Lijiang’s historical cultural space. The results show that terrain–habitat adaptability, water system coupling, and environmental risk avoidance shaped environmental adaptation; historical corridors, landscape perception, and core node associations organized spatial networks; and functional diversity, cultural capital agglomeration, and spatial-scale compatibility supported entity-based spatial practices. Although tourism development, urban expansion, and land-use transformation have not completely dismantled these historical relationships, they have caused localized deviations in ecological boundaries, path continuity, visual connections, functional vitality, and spatial scale. This study argues that the governance of historical cultural spaces should shift from preserving isolated heritage objects to sustaining cultural–ecological relationships that support memory, identity, spatial practice, and adaptive land governance.

Terraced vineyard landscapes represent complex cultural systems shaped by long-term interactions between geomorphology, agriculture and rural heritage. This study investigates the terraced viticultural landscape of Castiglione di Sicilia, located on the northern slope of Mount Etna (Sicily, Italy), through an integrated GIS-based framework combining Landscape Character Assessment (LCA), rural micro-structure mapping, visibility analysis and slow mobility assessment. Attention was given to dry-stone walls and traditional rural micro-structures, recognized as key components of the historical landscape identity of Etna. The methodology integrated geomorphological variables, vineyard distribution, dry-stone wall density and slope suitability within a Rural Micro-Structure Intensity Framework (RMSI) developed to identify areas characterized by stronger continuity of terraced rural landscapes. A sensitivity analysis was performed to evaluate the robustness of the weighting scheme. Slow mobility corridors were subsequently analyzed according to their relationship with landscape continuity and scenic visibility. The results reveal a strong spatial association between vineyards, dry-stone wall systems and historically structured terraced landscapes. Visibility analysis highlighted that highly visible areas do not fully correspond to the highest RMSI values, reflecting the geomorphological complexity of the volcanic environment. The corridor providing the best balance between scenic visibility, rural heritage continuity and route accessibility emerged as the most suitable option for landscape-oriented planning. The proposed framework supports landscape-sensitive planning and sustainable territorial valorization in Mediterranean terraced agricultural systems. Full article

Ecological security is fundamental to achieving the United Nations Sustainable Development Goals (SDGs) and maintaining ecosystem stability in ecologically sensitive regions. Mountainous protected areas, where ecological fragility and human pressure coexist, require dynamic evaluation frameworks that go beyond static pattern description. This study proposes an extended SPMOR (State–Pressure–Modelling–Optimization–Response) framework to assess the spatiotemporal evolution of ecological security in the Fanjingshan Mountain Region, a UNESCO World Heritage Site in Southwest China. Multi-source environmental and socio-economic datasets were standardized, objectively weighted using the CRITIC method, and integrated to construct a grid-based Ecological Security Index (ESI) for 2002, 2007, 2012, 2017, and 2022. Spatial autocorrelation analysis with global and local Moran’s I was employed to identify clustering patterns and temporal shifts. Results show that the average ESI increased from 0.4983 in 2002 to a peak of 0.5238 in 2012, before declining to 0.4945 in 2022. Global Moran’s I remained consistently high, ranging from 0.6516 to 0.6862, indicating persistent spatial clustering of ecological security. Spatially, the region exhibited a stable core–periphery structure, with high-security zones concentrated in the core reserve and low-security clusters distributed along human activity corridors. These findings suggest the coexistence of ecological restoration effects and renewed development pressures in mountainous protected areas. The proposed SPMOR framework provides a structured and potentially applicable approach for ecological security evaluation and offers practical insights for sustainable management of mountainous protected regions.

To investigate the effects of different surface coating treatments on the fire resistance of Qing Dynasty traditional corridor-style timber structures, the Long Corridor of the Beijing Summer Palace was selected as the case study. Two representative timber species, red pine and larch, were examined under three treatment conditions, including no treatment, traditional treatment (“San-dao-hui” and “Yi-ma-wu-hui”), and composite treatment combining traditional treatment with modern flame-retardant coatings. Cone calorimeter (CC) testing and Fire Dynamics Simulator (FDS) simulation were used to systematically investigate their combustion performance and fire spread patterns. Results indicate a clear, gradual improvement in timber reaction to fire: composite treatment coating performed best, followed by plaster layer protection, and untreated wood performed the worst. Among these, the composite treatment of red pine with “Yi-ma-wu-hui” (one hemp layer and five lime plaster layers) combined with modern flame-retardant coating showed the highest overall efficacy. The time to ignition (TTI) reached 76.7 s, a 210.5% increase compared with untreated wood. Meanwhile, peak heat release rate and carbon monoxide production were both significantly reduced. Notably, the selected modern flame-retardant coating cures colorless and transparent, preserving the original appearance of the wood, and the composite treatment maintains the historical texture and color consistency required for heritage restoration. The flame-retardant efficiency of the “Yi-ma-wu-hui” plaster layer was superior to that of the “San-dao-hui” (three lime plaster layers), owing to its denser structure that provides a stronger physical barrier effect. Larch exhibited better inherent reaction to fire than red pine, and surface coating treatments effectively reduced differences between substrates. FDS simulations confirmed that the composite treatment could keep peak heat release rate below 6000 kW under the most adverse meteorological conditions, confining high temperatures and dense smoke near the ignition point and effectively restraining sequential fire spread in traditional corridor-style timber structures. These findings provide a scientific basis and practical guidance for the fire-resistant restoration of Qing Dynasty traditional corridor-style timber structures and similar heritage buildings.
