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.

With the rapid urbanization and electrification in recent years, investment construction power infrastructure have been strengthened. Although it has a positive impact on economic development energy distribution, ecological landscape impacts brought by of related auxiliary facilities are often overlooked. To achieve harmonious relationship between protection, this study aims at transmission transformation projects corridors connectivity. By coupling morphological spatial pattern analysis least-cost path model, regional first constructed. In addition, influences connectivity can be evaluated compared. This framework is verified through case Shandong Province China. The results indicated that had significant migration resistance landscapes, impeding formation for species. Additionally, these exerted pronounced cutting effect reducing corridor permeability It crucial to preserve habitats major sources while maintaining developing nodes along key corridors. findings contributed harmonization planning providing reference future layout project development.

As a primary concern in the ecosystem, understanding impact of spatial heterogeneity ecological networks on development environmental sustainability has overarching significance. The Tibetan Plateau’s edge is vital contribution to study plateau’s network. However, there are few studies and explorations county-level network arid region. This aimed evaluate patterns Tianzhu County establish an security evaluation index system. We used minimum cumulative resistance (MCR) model built surface from exploratory data analysis (ESDA) method. Then, by identifying corridors nodes gravity model, we analyzed pattern proposed specific plans for optimizing situation. results showed that 1) county overall been lower, its values each direction, 2) Z-Score was 70.1893, which shows vulnerability region significant autocorrelation. identified 156 112 nodes, formed “one belt three zones.” Our analytical framework offers valuable tool constructing selecting “sources” at regional scale, can be applied landscapes geographical contexts sustainable regions.

In large urban agglomerations with fragmented landscapes, the relationship between habitat quality driving mechanisms and county ecological network weights has not yet been revealed. This study investigated metropolitan area of Changsha-Zhuzhou-Xiangtan agglomeration (CZXUA), focusing on birds, modified model Normalised Difference Vegetation Index (NDVI), to explore contribution factors spatial heterogeneity bird (HQb) force at global local scales. Ecological networks were identified based appropriate distance thresholds, weight was calculated gravity model. The results showed that: (1) scale, human disturbance HQb continued increase, up 73%. All non-linear effects. fit landscape pattern low, suggesting linear regression relationships. Mosaic filling-induced improvement depends trade-offs patch spacing penetration degree different patches. (2) source degradation, corridor fragmentation, out-migration over time. interaction Xiangtan County Lukou District decreased from 1357145 896077, while Changsha increased slightly 99035 107641. Landscape fragmentation direct cause decrease in weight, geocentric transfer indirect cause. (3) Habitat can be an explicit indicator, a constantly fluctuating implicit indicator. A may acquire sources more degraded neighbouring counties become new hub. It is important evaluate changes weighting so as determine their vulnerability spaces likelihood being threatened by affecting them, avoid neglecting benefits due habitats. These findings could provide suggestions for restoration connectivity strategies agglomerations.
