With the acceleration of modernization, villages in Southwest China are experiencing spatial fragmentation and homogenization, leading to the loss of traditional identity. Addressing how to balance scientific planning with cultural and spatial continuity has become a key challenge in rural governance. This study takes Xuyong County in Luzhou City as a case and develops a three-tier analytical framework—“genome–spatial factors–specific indicators”—based on the space gene theory to identify, classify, and map spatial patterns in marginal villages of southern Sichuan. Through cluster analysis, common and distinctive spatial genes are extracted. Common genes—such as medium surface roughness (GeneN-2-b), medium building dispersion (GeneA-3-b), and low intelligibility (GeneT-2-b)—are prevalent across multiple village types, reflecting shared adaptive strategies to complex terrains, ecological constraints, and historical development. In contrast, distinctive genes—such as high building dispersion (GeneA-3-a) and linear boundaries (GeneB-1-c)—highlight unique spatial responses that are shaped by local cultural and environmental conditions. The results contribute to a deeper understanding of spatial morphology and adaptive mechanisms in rural settlements. This research offers a theoretical and methodological basis for village classification, conservation zoning, and spatial optimization, providing practical guidance for rural revitalization efforts focusing on both development and heritage protection.

The spatial genes of rural settlements show a lot of different traditional settlement traits, which makes them a great starting point for studying rural spatial morphology. However, qualitative and macro-regional statistical indicators are usually used to find and extract rural settlement spatial genes. Taking Yubei Village in the Nanxi River Basin as an example, this study combined remote sensing images, real-time drone mapping, GIS (geographic information system), and space syntax, extracted 12 key indicators from five dimensions (landform and water features (environment), boundary morphology, spatial structure, street scale, and building scale), and quantitatively “decoded” the spatial genes of the settlement. The results showed that (1) the settlement is a “three mountains and one water” pattern, with cultivated land accounting for 37.4% and forest land accounting for 34.3% of the area within the 500 m buffer zone, while the landscape spatial diversity index (LSDI) is 0.708. (2) The boundary morphology is compact and agglomerated, and locally complex but overall orderly, with an aspect ratio of 1.04, a comprehensive morphological index of 1.53, and a comprehensive fractal dimension of 1.31. (3) The settlement is a “clan core–radial lane” network: the global integration degree of the axis to the holy hall is the highest (0.707), and the local integration degree R3 peak of the six-room ancestral hall reaches 2.255. Most lane widths are concentrated between 1.2 and 2.8 m, and the eaves are mostly higher than 4 m, forming a typical “narrow lanes and high houses” water town streetscape. (4) The architectural style is a combination of black bricks and gray tiles, gable roofs and horsehead walls, and “I”-shaped planes (63.95%). This study ultimately constructed a settlement space gene map and digital library, providing a replicable quantitative process for the diagnosis of Jiangnan water town settlements and heritage protection planning.

An important historical and cultural region in southern China, the Xiangjiang River Basin, has formed a unique spatial pattern and regional cultural characteristics in its long-term development. In recent years, the acceleration of urbanization has led to the historical texture and cultural elements of Changsha’s suburban blocks facing deconstruction pressure. How to identify and protect their cultural value at the spatial structure level has become an urgent issue. Taking three typical traditional township blocks in the suburbs of Changsha as the research object, this paper constructs a trinity research framework of “spatial gene identification–diversity analysis–strategy optimization.” It systematically discusses the makeup of the types, quantity, distribution, relative importance ranking, and diversity characteristics of their spatial genes. The results show that (1) the distribution and quantity of spatial genes are affected by multiple driving forces such as historical function, geographic environment, and settlement evolution mechanisms, and that architectural spatial genes have significant advantages in type richness and importance indicators; (2) spatial gene diversity shows the structural characteristics of “enriched artificial space and sparse natural space,” and different blocks show clear differences in node space and boundary space; (3) spatial genetic diversity not only reflects the complexity of the spatial evolution of a block but is also directly related to its cultural inheritance and the feasibility of renewal strategies. Based on this, this paper proposes strategies such as building a spatial gene database, improving the diversity evaluation system, and implementing differentiated protection mechanisms. These strategies provide theoretical support and methods for the protection and sustainable development of cultural heritage in traditional blocks. Full article

Guomari fortress in eastern Qinghai Province exemplifies vernacular architecture shaped by multiethnic interaction, environmental adaptation, and localized defense strategies. Originally a Ming Dynasty military-agricultural outpost, it evolved into a Tu ethnic settlement. Fieldwork, including architectural surveys and spatial analysis, identified a three-tiered defensive system: (1) strategic use of terrain and rammed-earth walls; (2) labyrinthine alleys with L-, T-, and cross-shaped intersections; and (3) interconnected rooftops forming elevated circulation routes. Courtyards are categorized into single-line, L-shaped, U-shaped, and fully enclosed layouts, reflecting adaptations to terrain, ritual functions, and thermal needs. Architectural features such as thick loam-coated walls and flat roofs demonstrate climatic adaptation, while the integration of Han timber frameworks, Tibetan prayer halls, and Tu decorative elements reveals cultural convergence. Traditional craftsmanship, including carved wooden scripture blocks and tsampa-based murals, is embedded within domestic and ritual spaces. The fortress’s circulation patterns mirror Tibetan Buddhist cosmology, with mandala-like alleys and rooftop circumambulation routes. These findings offer insights into vernacular resilience and inform conservation strategies for multiethnic fortified settlements. Full article

In the context of rapid urbanization, traditional villages in the Weibei Loess Plateau gully region are facing compounded pressures from social structure disruption and physical space reconstruction. It is urgent to deeply analyze the influence mechanism of social relations on spatial adaptability. This study attempts to construct an analytical framework that couples social relationships with village spatial development. With Tangjia Village in the gully region of the Weibei Loess Plateau as an example, the study integrated various data sources such as satellite imagery, interviews, and policy documents. Through social network analysis and an improved cascade failure model, the spatial adaptation processes and characteristics based on changes in kinship, occupational ties, and geographical networks were explored. The findings indicate that (1) before 2001, kinship networks led to the formation of a monocentric settlement structure. From 2001 to 2011, occupational ties fostered the differentiation of industrial and residential zones. After 2011, geographical networks drove the multifunctional integration of space. (2) Clan-based settlement zones (consisting of 80 kinship nodes) and core cultural tourism facilities are key units in maintaining spatial adaptability. The research reveals the impact mechanism of social network fission on spatial function reorganization and proposes adaptive planning strategies, aiming to provide theoretical and practical value for the coordinated governance of society and space in traditional villages.

With the ongoing globalization, traditional villages around the world face the challenge of balancing modernization with the preservation of their cultural and spatial integrity. Heijing Village, a representative traditional settlement in Yunnan, showcases this global phenomenon through its distinctive spatial form and rich multi-ethnic cultural heritage. This study examines the landscape morphology of Heijing Village to reveal its spatial organization, cultural significance, and adaptive evolution. By applying fractal theory, we quantify the spatial complexity and self-similarity of the village, uncovering underlying patterns in land use that contribute to its sustainability and historical continuity. This study’s innovation lies in its use of fractal analysis to assess the village’s dynamic landscape, offering a novel method for understanding the interplay between traditional spaces and modern demands. The findings demonstrate variations in fractal dimension values before and after model optimization, indicating an enhanced ability to capture the intricate spatial structure of Heijing Village. Notably, changes in fractal dimensions across different land use types (e.g., residential areas: 1.4751 to 1.5323 and public service areas: 1.2846 to 1.3453) suggest improvements in quantification accuracy rather than actual physical transformations. This refined methodological framework provides a robust and replicable tool for planners to quantitatively assess the morphological characteristics of traditional settlements, supporting more evidence-based conservation strategies.

With the increasing global population and migration toward coastal regions, and the rising demand for coastal urbanization, including the development of living spaces, ports, and tourism infrastructure, the need for coastal defense structures (CDSs) is also increasing. Traditional CDSs, such as breakwaters, typically composed of hard units designed to block and divert wave and current energy, often fail to support diverse and abundant marine communities because of their impact on current and sediment transport, the introduction of invasive species, and the loss of natural habitats. Marine ecoengineering aims at increasing CDS ecological services and the development of marine organisms on them. In this study, carried out in a coral reef environment, we examined the relationship between coral colony protection levels and three factors related to their development, namely, coral fragment survival rate, larval settlement, and water motion (flow rate), across three distinct niches: Exposed, Semi-sheltered, and Sheltered. Coral survivability was assessed through fragment planting, while recruitment was monitored using ceramic settlement tiles. Water motion was measured in all defined niches using plaster of Paris Clod-Cards. Additionally, concrete barrier structures were placed in Exposed niches to test whether artificially added protective elements could enhance coral fragment survival. No differences were found in coral settlement between the niches. Flow rate patterns remained similar in Exposed and Sheltered niches due to vortex formation in the Sheltered zones. Survival analysis revealed variability between niches, with the addition of artificial shelter barriers leading to the highest coral fragment survival on the breakwater. This study contributes to the development of ways to enhance coral development with the goal of transforming artificial barriers into functional artificial reefs. Full article

Traditional settlements are vital carriers of Chinese agricultural civilization yet face mounting challenges in protection and inheritance amid rapid urbanization. Taking ancient Huizhou as a case study, this research analyzes the spatial distribution patterns of cross-provincial traditional settlements and constructs a multi-level heritage corridor network through circuit theory modeling and space syntax analysis. The study reveals a “small aggregation, large dispersion” spatial structure shaped by natural geography and socio-cultural dynamics. Simulation of multi-path cultural flows and network analysis show that high betweenness corridors concentrate along the northeast–southwest axis, promoting efficient cultural circulation, while low betweenness areas highlight gaps in direct connectivity. Closeness analysis identifies She County as the cultural core with a single-center radial structure, though internal fragmentation persists. Based on these findings, the study proposes a “three-core-driven, two-axis linkage, multi-source synergy” protection strategy to strengthens the spatial integrity and resilience of the heritage network. This research not only provides a systematic framework for the holistic conservation of Huizhou settlement heritage but also offers methodological references for the protection of traditional settlements in broader regions.

The development trend of urban underground space towards deep and large three-dimensional foundation pit projects in complex environments faces the challenges of deformation and instability of supporting structures, strong sensitivity of the surrounding environment, and significant limitations of the traditional design theory. Based on the ultra-long/deep foundation pit project at the Shenzhen Airport East Station, a refined three-dimensional finite element simulation is used to systematically study the deformation mechanism of the supporting structures of deep and large foundation pits under a complex environment and investigate the influence on the neighbouring buildings. In this study, a three-dimensional finite element model is constructed considering the soil–structure coupling effect, and the mechanical response law of the foundation pit under the compliant–inverse combination method is revealed. Based on ABAQUS 6.14, a 10 m wide strip-shaped model of the central island area and an environmental risk source model including an underground station and group pile foundation are established. The analysis shows the following: the lateral shift in the ground wall is distributed in a ‘convex belly’ shape, with a maximum displacement of 29.98 mm; the pit bottom is raised in the shape of the bottom of a rebutted pot, and the settlement behind the wall has an effect ranging up to 3.8 times the depth of the excavation; the lateral shift in the side wall of the neighbouring underground station and the differential settlement of the group piles validate the predictive ability of the model on the complex-environment coupling effect. The research results can provide guidance for the design and construction of support structure projects and similar projects. Full article

The Zaatari Camp in Jordan exemplifies how Syrian refugees transform a planned grid settlement into an organic urban environment through socio-spatial adaptation, reflecting their cultural identity and territorial practices. This study investigates the camp’s morphological evolution, analyzing how refugees reconfigure public and private spaces to prioritize privacy, security, and community cohesion. Using qualitative methods—including archival maps, photographs, and field observations—the research reveals how formal public areas are repurposed into private shelter extensions, creating zones of influence that mirror traditional Arab-Islamic urban patterns. Key elements such as mosques, markets, and hierarchical street networks emerge as cultural anchors, shaped by refugees’ prior urban experiences. However, this organic growth introduces challenges, such as blocked streets and undefined spaces, which hinder safety and service delivery, underscoring tensions between informal urbanization and structured planning. The findings advocate urban resilience and participatory planning frameworks that integrate socio-cultural values, emphasizing defensible boundaries, interdependence, and adaptable design. Refugees’ territorial behaviors—such as creating diagonal streets and expanding shelters—highlight their agency in reshaping urban systems, challenging conventional top-down approaches. This research focuses on land-use dynamics, sustainable cities, and adaptive urban systems in crisis contexts. By bridging gaps between displacement studies and urban theory, the study offers insights into fostering social inclusion and equitable infrastructure in transient settlements. Future research directions, including comparative analyses of refugee camps and cognitive mapping, aim to deepen understanding of socio-spatial resilience. Ultimately, this work contributes to global dialogues on informal urbanization and culturally responsive design, advocating for policies that align with the Sustainable Development Goals to rebuild cohesive, resilient urban environments in displacement settings.

Refugee camps are typically designed as temporary sustainable settlements, prioritizing logistics over cultural considerations, which can lead to environments being misaligned with the lived experiences of displaced populations. This study addresses the challenge of traditional humanitarian camp designs that prioritize logistical efficiency over cultural and socio-cultural needs, leading to environments that do not align with the lived experiences of displaced populations. Focusing on the Zaatari Syrian Refugee Camp in Jordan, the research employs a structured questionnaire distributed among 102 households to investigate how refugees have reconfigured the camp’s original grid layout into more cohesive clustered patterns, informed by the principles of defensible space theory. Key findings reveal that refugees actively transform public courtyards into semi-private spaces, driven by cultural imperatives and safety needs. Statistical analyses confirm significant correlations between clustering behaviors and the attributes of defensible space, particularly the zones of influence and boundary demarcation, enhancing community resilience and accessibility. However, the study finds a limited predictive power overall, indicating that while these adaptations are significant, factors such as natural surveillance and territorial behavior do not exhibit strong influences on clustering dynamics. These findings have important implications for humanitarian planning and design. They highlight the necessity for more culturally sensitive and flexible approaches that prioritize refugee agencies and communal identity in camp layouts. This research advocates for a hybrid planning approach that integrates socio-cultural values, promoting resilience and quality of life among refugees. By aligning spatial designs with the social and cultural realities of refugee communities, humanitarian actors can enhance the effectiveness of their interventions, ultimately contributing to more sustainable and inclusive urban environments as part of broader goals related to urban planning and development. Future research is encouraged to explore these practices in diverse refugee contexts, providing further validation of these findings and enhancing the applicability of these design principles in global humanitarian efforts.

Due to the imbalance between urban and rural development and improper management, the spatial forms of many heritage villages have suffered severe damage, and their landscape styles are gradually being blurred, posing serious challenges to the protection of traditional villages. Taking the traditional village of Xi Songbi in Jiexiu City, Shanxi Province, as a case study, this paper employs UAV low-altitude multi-view measurement technology to obtain high-resolution image data from different angles. Three-dimensional modeling technology is then used to construct a 3D real-world model, orthophotos, and point cloud data of the settlement. Based on these data, the weakly supervised point cloud segmentation method, DDLA, is further applied to finely segment and classify the acquired point cloud data, accurately extracting key spatial elements such as buildings, roads, and vegetation, thereby enabling a comprehensive and quantitative analysis of the spatial morphology of traditional villages. The results of the study show the following: (1) The use of UAVs for low-altitude multi-view measurement not only greatly improves the efficiency of data acquisition but also provides millimeter-level precision spatial data in a short time through the constructed 3D models and orthophotos. (2) The acquired point cloud data can be processed through the DDLA, which effectively differentiates building contours from other environmental elements. (3) The calculation and analysis of the segmented point cloud data can accurately quantify key spatial morphology elements, such as the dimensions of traditional village buildings, spacing, and road widths, ensuring the scientific rigor and reliability of the data. (4) The comprehensive application of digital technology and point cloud segmentation methods provides clear expectations and solid technical support for the quantitative study of the spatial morphology of traditional villages, laying a scientific foundation for the protection and sustainable development of cultural heritage.

In recent years, rural return has emerged as a significant trend in China, largely driven by central and local government policies promoting rural revitalization and urban-to-rural migration. This study aims to explore the impact of rural return on the evolution of rural spaces at the village level in China, with a particular focus on how urban-to-rural migration reshapes village spatial structures. This study examines the spatial implications of this phenomenon through case studies of three traditional villages in Zhejiang Province, utilizing qualitative fieldwork, spatial mapping, and in-depth interviews. By analyzing migration patterns, residential choices, and subsequent spatial transformations, this research elucidates how urban-to-rural migrants reshape spatial structures at the village level and integrate into local communities. The research findings reveal that the proportion of the migrant population is less than 30%, yet this relatively small proportion has brought significant changes to the village, manifested in the substantial increase in third spaces within the village. The study also identifies ten distinct migration types within the sample, with short-term residency comprising the majority, and migrants’ relocation needs play a crucial role in determining spatial adaptations. The predominant strategy for village integration involves the functional transformation of traditional dwellings into mixed-use commercial and residential spaces, as well as the renovation of existing structures to accommodate new social and economic activities. Additionally, the study underscores the active participation of migrants in public life and communal spaces as a key driver of spatial regeneration. This research contributes to the understanding of rural transformation in contemporary China by demonstrating that urban-to-rural migration not only reshapes village spatial configurations but also catalyzes social and functional revitalization. These insights provide a nuanced perspective on the evolving dynamics of rural settlements and inform future rural development strategies. Full article

The traditional design of foundations in soft clay often relies on large-diameter piles, which, although effective, are costly and impractical for low- to medium-rise buildings. Micropiles have emerged as a cost-effective alternative, offering an efficient solution to these challenges. To advance the adoption of micropiles in geotechnical practice, this study employs a multi-objective genetic algorithm-based evolutionary polynomial regression (EPR-MOGA), a hybrid artificial intelligence method, to develop a robust and straightforward model for predicting the load–settlement response of micropiled rafts in cohesive soils under vertical loads. The model was created using an extensive database comprising 458 data points derived from field tests, centrifuge experiments, laboratory studies, and numerical simulations reported in the literature. This comprehensive database covers a wide range of scenarios by varying key parameters of micropiles within a group, including their length, diameter, number, spacing, construction method, and raft thickness. The proposed EPR model could deliver accurate predictions, providing a practical approach for geotechnical applications. In addition, the predictions of the model could support the conclusion that pressure-grouted micropiles are more efficient than gravity-grouted ones in enhancing the performance of micropiled rafts.

As urbanization progresses in China, the importance of preserving traditional settlements, particularly those located in mountainous areas, is increasingly recognized. To reveal the spatial morphology of mountain settlements influenced by topography, this study employs fractal geometry to analyze twelve mountain settlements within the Jiexiu City region. The correlation between the fractal dimensions of building structures in these settlements and those of suitable construction areas was examined, revealing a significant positive relationship. Moreover, an in-depth spatial distribution analysis of the representative village, Xingdi Village, was conducted to examine its sub-regional spatial morphology. Utilizing the Multiscale Geographically Weighted Regression (MGWR) model, this study explored the impact of slope, aspect, and elevation on the spatial form of mountainous settlements. The results indicate that the complexity of sub-spaces within Xingdi Village gradually decreases with village expansion, and there is a significant positive correlation between flat terrain and sub-spatial morphology. Based on this, a conservation framework rooted in the morphological characteristics of settlement typologies is proposed. Full article
