Dark skies, a vital natural and cultural resource, have been increasingly threatened by light pollution due to rapid urbanization, leading to ecological degradation and biodiversity loss. As a key strategy for sustainable regional development, dark sky parks (DSPs) not only preserve nocturnal environments but also enhance livability by balancing urban expansion and ecological conservation. This study develops a novel framework for evaluating DSP suitability, integrating ecological and socio-economic dimensions, including the resource base (e.g., nighttime light levels, meteorological conditions, and air quality) and development conditions (e.g., population density, transportation accessibility, and tourism infrastructure). Using the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) as a case study, we employ Delphi expert consultation, GIS spatial analysis, and multi-criteria decision-making to identify optimal DSP locations and prioritize conservation zones. Our key findings reveal the following: (1) spatial heterogeneity in suitability, with high-potential zones being concentrated in the GBA’s northeastern, central–western, and southern regions; (2) ecosystem advantages of forests, wetlands, and high-elevation areas for minimizing light pollution; (3) coastal and island regions as ideal DSP sites due to the low light interference and high ecotourism potential. By bridging environmental assessments and spatial planning, this study provides a replicable model for DSP site selection, offering policymakers actionable insights to integrate dark sky preservation into sustainable urban–regional development strategies. Our results underscore the importance of DSPs in fostering ecological resilience, nighttime tourism, and regional livability, contributing to the broader discourse on sustainable landscape planning in high-urbanization contexts.

Urban wetlands are increasingly recognized for their ecological and cultural benefits, yet remain underutilized due to limited public awareness and environmental literacy. This study investigates how visitors’ perceptions of wetland ecosystem services influence their motivations to engage with a constructed wetland in Putrajaya, Malaysia. By integrating the ecosystem services framework with push-pull motivation theory, the research aims to bridge knowledge gaps and inform sustainable wetland tourism planning. A structured questionnaire was administered to 420 visitors, with 385 valid responses (response rate: 91.7%). Data were analyzed using non-parametric tests (Kruskal–Wallis, Spearman correlation) and multiple regression analysis. Results show that cultural and regulating services are perceived most positively, while emotional restoration and aesthetic appreciation emerged as key motivational drivers. Regression findings reveal that push factors are stronger predictors of ecosystem service engagement than pull factors. These insights highlight the importance of emotional and psychological connections to nature, offering practical implications for urban wetland management, visitor education and environmental communication strategies.

Microplastics (MPs) have emerged as a critical environmental challenge in China’s aquatic ecosystems, driven by rapid industrialization and population growth. This review synthesizes recent findings on the abundance, morphology, and polymer types of MPs in China’s freshwater systems (rivers, lakes, reservoirs) and coastal marine environments. Spatial analysis reveals significant variability in MP abundance, ranging from 0.1 items/L in Tibet’s Lalu Wetland to 30.8 items/L in Beijing’s Qinghe River, with polypropylene (PP) and polyethylene (PE) dominating polymer profiles. Coastal regions exhibit distinct contamination patterns, with the Yellow Sea (5.3 ± 2.0 items/L) and the South China Sea (180 ± 80 items/m³) showing the highest MP loads, primarily as fibers and fragments. Fluvial transport, atmospheric deposition, and coastal anthropogenic activities (e.g., fisheries, tourism) are identified as major pathways for marine MP influx. Secondary MPs from degraded plastics and primary MPs from industrial/domestic effluents pose synergistic risks through the adsorption of heavy metals and organic pollutants. Human exposure routes—ingestion, inhalation, and dermal contact—are linked to inflammatory, metabolic, and carcinogenic health outcomes. Policy interventions, including bans on microbeads and non-degradable plastics, demonstrate progress in pollution mitigation. This work underscores the urgency of integrated source control, advanced wastewater treatment, and transboundary monitoring to address MP contamination in aquatic ecosystems. Full article

The rapid pace of urbanization is contributing to ecological degradation and poses a threat to regional ecological security. Addressing these issues requires effective strategies to mitigate existing environmental challenges. Ecological networks, as the spatial foundation for ecosystem services, play a critical role in reducing environmental degradation. By reconfiguring the spatial relationship between human activities and natural ecosystems, anthropogenic pressures on land can be alleviated. However, most current research focuses on administrative boundaries, which limits spatial continuity and regional coordination. Therefore, constructing ecological networks from a cross-regional perspective is essential for integrated ecological management. This study uses the Yangtze River Delta Ecological Green Integration Demonstration Area as a case study. We construct a blue–green ecological network by applying ecological footprint analysis, Morphological Spatial Pattern Analysis (MSPA), landscape connectivity assessments, the Minimum Cumulative Resistance (MCR) model, and gravity modeling. Practical strategies for integrating the ecological network into territorial spatial planning are also explored. The key findings are as follows: (1) The demonstration area contains 33 ecological source areas, including 20 primary sources located near administrative boundaries and central lakeshore wetlands. A total of 333 ecological corridors were identified. First-grade corridors are primarily located in rural areas, traversing agricultural land and water bodies. (2) We recommend corridor widths of 200 m for first-grade corridors, 60 m for second-grade corridors, and 30 m for third-grade corridors. These widths are based on species characteristics and land use types, and are found to be conducive to species migration and habitat connectivity. (3) We propose the development of tourism landscape zones from a cross-regional perspective, leveraging existing ecological and cultural resources. The multifunctionality of corridors is redefined through the integration of ecological and social values, enhancing their spatial implementation. This framework provides a practical reference for constructing cross-regional blue–green ecological networks and informs spatial planning efforts in other multi-jurisdictional areas. Full article

Ecosystems, water supplies, and tourism all benefit from the protection of forest regions. All the above affect the possibility for tourism to prosper in forested areas. Tikvara Nature Park (TNP) has significant tourist potential for the development of specific and sustainable forms of tourism because it has direct contact with the Danube River, which forms the Upper Danube Region. This nature park has a significant forested area, inhabited by rare species of flora and fauna. In addition, there are wetlands, which are inhabited by rare species of birds, aquatic animals, and plants. Ecological and socio-cultural sustainability are the subjects of research in this article. It was possible to observe all possibilities for the growth of tourism based on nature by analyzing sustainable tourism by applying an extended PoS study method. The results of this research indicate that the two examined dimensions have a significant impact on the state and perspective of tourism development in this nature park. Also, sustainable tourism has an impact on the satisfaction of respondents through ecological and socio-cultural factors of the destination. Analysis of the results indicates that the respondents are ready to harmonize their activities with ecological principles in this protected area. Researching these two dimensions of sustainable tourism development (STuD) is important for tourism planning, growth, and nature protection control. This study’s significant results demonstrate the importance of environmental and socio-cultural elements for tourism development (ToD), and their substantial influence on tourism sustainability (ToS) and local and visitor satisfaction. Plans for the growth of sustainable tourism might be significantly influenced by research findings. Full article

Balancing ecological conservation and economic development is a significant global challenge, particularly in developing countries where rich natural resources often coincide with impoverished areas. This study used the Yunhe Terrace as a case, integrating remote sensing data and statistical analysis to quantify the ecosystem asset value and its changes before and after ecological conservation efforts. Additionally, we assessed the nonmaterial service value and conducted a questionnaire survey to explore the impact of nonmaterial service value on the socio-economic development of local residents. The key findings are as follows: (1) The ecosystem assets of the Yunhe Terrace include four main types: forests, grasslands, wetlands, and cultivated land. In 2020, the Yunhe Terrace ecosystem was primarily composed of forest (56.79%) and cultivated land (36.61%), showing a balance between natural and modified landscapes. (2) The monetary value of ecosystem assets was calculated based on the economic net benefits of ecosystem assets over their expected useful lifespan (20 years in this study). The value of the Yunhe Terrace ecosystem before and after it became a scenic spot was assessed. Results showed that the total value of ecosystem assets increased from 265 million CNY to 523 million CNY over a 20-year period, representing an increase of 257 million CNY. (3) The value of nonmaterial services, represented here by net revenues from eco-tourism, was calculated from 2018 to 2022, covering the period before and after ecological conservation efforts began in 2019. Results showed the value of nonmaterial services rose from 3.07 million CNY in 2018 to 8.90 million CNY in 2022, a growth of 189.77% after ecological conservation. (4) Field surveys and questionnaire analysis of stakeholders’ income sources suggest that ecological conservation and recreational development in the Yunhe Terrace ecosystem have increased household income in terms of both the number of income sources and monetary value. This study demonstrates that ecological conservation and tourism can enhance household welfare, contributing to a better understanding of the dynamics between conservation and economic development.

This paper investigates the illegal activities that may negatively impact the environment in Croatia’s protected areas, particularly those associated with tourism. Failure Mode and Effects Analysis (FMEA) and sensitivity analysis are used to identify distinct high-risk activities specific to different park types. Coastal parks are found to be particularly vulnerable to maritime-related illegal activities, with high risk exposure from mooring vessels and swimming in prohibited areas. These parks also face significant risks from illegal fishing and the capture of strictly protected plants and animals, highlighting the need for enhanced marine ecosystem protection. Mountainous and forest parks face significant risks from fire-related activities, while wetland parks are sensitive to poaching and illegal fishing. Additionally, diverse landscape parks show increased vulnerability to littering, poaching, and the collection or harvesting of strictly protected plants and animals. The results underscore the necessity for tailored risk-management strategies that prioritize interventions based on park-specific challenges. By addressing the unique vulnerabilities of each park type, this study contributes insights into mitigating environmental threats posed by tourism and emphasizes the importance of continuous monitoring and adaptive management in protected areas.

Wetlands are crucial for sustainable development, and the evaluation of their GEP is a key focus for governments and scientists. This study created a dynamic accounting model for wetland GEP and assessed the GEP of 39 wetlands in the middle reaches of the Yellow River in Ningxia province. The results indicate that Ningxia province’s wetlands have an average annual GEP of CNY 5.24 billion. Haba wetland contributes the most at 0.52, while Qingtongxia, Sha, and Tenggeli wetlands follow with 0.12, 0.04, and 0.03, respectively. Climate regulation is the most valuable function at 38.24%, with species conservation and scientific research/tourism at 24.93% and 15.11%, respectively. Ningxia’s northern wetlands are vast and shaped by the Yellow River, while the smaller, seasonal southern wetlands are more affected by rainfall and mountain groundwater. Southern wetlands show a strong correlation between GEP and precipitation (0.82), whereas northern wetlands have a moderate correlation between GEP and evapotranspiration (0.52). The effective conservation and management of these wetlands require consideration of their locations and weather patterns, along with customized strategies. To maintain the stability of wetland habitats and provide a suitable environment for various species, it is essential to preserve wetlands within a certain size range. Our study found a strong correlation of 0.85 between the wetland area and the GEP value, indicating that the size of wetlands is a key factor in conserving their GEP. The results provide accurate insights for creating a wetland ecological benefit compensation mechanism. Full article

The development of sustainable tourism has various stakeholders such as local residents, businesses, governments, visitors, travel agencies, and tourism companies. Tourism destinations need to be protected not only to ensure a better travel experience but also to ensure that they can be enjoyed in the future. This study explored the degree of influence of key stakeholders such as the government, travel agencies, local residents, and tourists on the development of sustainable tourism in Haikou, the capital city of the island province Hainan, China. This city is rich in tropical natural resources and offers unique opportunities for the development of tourism. In 2018, Haikou was selected as one of the first “International Wetland Cities” by the 13th United Nations Ramsar Convention. However, the high dependence on tourism and centralized consumption have caused several ecological and environmental problems in Haikou. An online questionnaire survey of 419 stakeholders was conducted, and factor analysis was used to identify five dimensions. The structural equation modeling method was used to explore the degree of influence of different relationships on sustainable tourism development in Haikou. The results indicated that key stakeholders are most concerned about tourism awareness, ecological protection, and sociocultural development. Therefore, further efforts to promote and develop tourism must focus on ecological and environmental protection. Creating positive travel experiences and managing tourism wisely can meet the demands of today without compromising the future. Full article

Urban wetlands represent a significant ecosystem type within urban landscapes. The quantitative assessment of their ecological service value holds great significance in guiding and improving the urban habitat. However, due to the insufficient spatial resolution of traditional low-to-medium resolution remote sensing imagery for surface monitoring, previous studies have conducted relatively limited research on the ecosystem services of urban wetlands. In this paper, based on multi-source data including multi-scale remote sensing data, a spatial-temporal fusion model and multiple ecological parameter inversion models were employed to invert three key ecological parameters at high spatial resolution, thereby assessing the ecosystem service values (ESVs) of urban wetlands. Taking the East Lake Scenic Area (ELSA) in Wuhan as an example, the dynamics of its ecosystem services’ value components were comparatively analyzed. The results indicate that, while the total value of ecosystem services declined slightly in 2015 compared to 2011, there was a notable increase in their value to CNY 3.219 billion by 2019, which represents a doubling of the total value relative to 2011. This trend could be primarily attributed to a significant rise in cultural services within the region. Specifically, the value of tourism services reached CNY 2.090 billion in 2019, representing a threefold increase compared to 2011. This demonstrates that ecosystem services in the ELSA have been significantly optimized and enhanced through associated ecological projects. Further research should investigate the mechanisms by which urbanization affects these crucial ecosystem services, particularly the characterization of cultural services in urban wetlands, and develop more effective strategies to enhance urban resilience and sustainable development.

Transitional waters (TWs) are relevant ecological and economical ecosystems that include estuaries, deltas, bays, wetlands, marshes, coastal lakes, and coastal lagoons and play a central role in providing food, protecting coastal environments, and regulating nutrients. However, human activities such as industrialization, urbanization, tourism, and agriculture are threatening these ecosystems, which results in contamination and habitat degradation. Therefore, it is essential to evaluate contamination in TW to develop effective management and protection strategies. This study analyses the application of geospatial technologies (GTS) for monitoring and predicting contaminant distribution in TW. Cartography, interpolation, complex spatial methods, and remote sensing were applied to assess contamination profiles by heavy metals, and persistent organic compounds, and analyze contamination indices or some physicochemical water parameters. It is concluded that integrating environmental and demographic data with GTS would help to identify critical points of contamination and promote ecosystem resilience to ensure long-term health and human well-being. This review comprehensively analyzes the methods, indicators, and indices used to assess contamination in transitional waters in conjunction with GTS. It offers a valuable foundation for planning future research on pollution in these types of waters or other similar water bodies worldwide. Full article
