Urban–rural fringes (URFs) are crucial for biodiversity yet often neglected in conservation efforts. This study refines URF habitat evaluation and integrates it into a coordinated ecological network (EN) territorial planning framework. Using Qingpu District, Shanghai as case study, we defined its via k-means clustering of night-time light data applied the InVEST model, MSPA, Integrated Habitat Value, Patch Importance, Betweenness Centrality analyses to identify high-value habitats. Furthermore, constructed EN using circuit theory evaluated impact sources on connectivity construction costs. Our findings reveal that integrating increased indices significantly (α by 127.18%, β 47.00%, γ 33.4%) decreased costs (CR index 0.07). Despite these benefits, under China’s “Three Zones Three Lines” policy, 78.18% Qingpu’s remain unprotected, with 56.78% at risk conversion land. proposes comprehensive system habitats strategic recommendations their incorporation regional ENs, thus informing policy making more inclusive conservation.

Regional ecological security is a pressing issue in the context of escalating human-environment conflicts. Ecological networks(ENs), fundamental tool for characterizing ecosystems, have enabled further quantitative analysis at micro level by integrating with complex networks recent years. However, most studies neglect unreliability unweighted and dynamic characteristics ENs. This paper takes Sichuan Basin as research area adopts following methods. Firstly, it integrates landscape ecology ecosystem services to construct ENs using Linkage Mapper. Secondly, introduces cost-weighted distance weight build identifies potential pivot sources key corridors based on topological features weighted 2000, 2010, 2020. Thirdly, applies circuit theory detect pinchpoints barrier points within priority areas conservation restoration.

Metropolitan regions usually encounter sustainability difficulties such as overexploitation of resources, severe land scarcity, and ecological degradation, resulting in the progressive collapse networks (ENs). It is therefore essential to strengthen construction protection ENs by integrating various improving quality urban environment creating a favourable living environment. Using Guangdong-Hong Kong-Macao Greater Bay Area case study, this paper, resistance indicator system that balances natural condition human disturbance rebuilt. In doing so, scheme (applicable highly urbanised areas) established simulate at more precise scale. Moreover, local evaluation model proposed spatial patterns multiple indicators are fully summarised. The findings show exhibit apparent disparity. Disturbance through activities seriously affects pattern ENs, leading structural imbalance impairment corridors. Based on our assessment, complementary corridors "two green belts" planning will improve problems. paper can provide reference harmonisation development protection, guiding scientific management spaces regions.

In the context of accelerating ecological fragmentation, it is urgent to enhance interconnectivity urban patches form a resilient network (EN). The construction Natural Protected Area (NPA) system proposed in 2019 latest strategy implemented by China protecting spaces. However, effectiveness this has not been adequately demonstrated. This study specifically analyzes concrete impacts natural protected area on resilience networks (ENs). economically developed Urban Agglomeration around Hangzhou Bay (UAHB) was chosen as an example for argumentation. Firstly, we utilized circuit theory construct EN consisting 173 sources and 401 corridors. Secondly, were categorized into three levels based their connectivity values. Finally, dynamic disturbance scenario simulation framework constructed evaluate impact NPA EN. results indicated that: (1) preceding 47% are crucial maintaining EN; (2) Compared with other spaces, NPAs have 38% 1100% greater effect first second-level sources, respectively, while its third-level 118% lower. innovatively investigates differential hierarchical areas unprotected environment.
