Strong soil erosion and increasing human activities have made Loess Plateau areas ecologically fragile regions. Constructing the ecological security pattern (ESP) is imperative to maintain their ecosystem functions sustainable development. However, it still challenging establish ESP in such an unstable scattered environment. In this study, we take Shanxi Province, which suffers severe problems areas, as example construct a of “source-resistance-corridor”. The proposed methods include following steps: (1) potential sources are selected with important based on contributions water conservation, habitat quality, carbon storage; (2) determined by considering core at landscape scale morphological spatial analysis (MSPA) along stability dynamic assessment previous sources; (3) comprehensive resistance surface constructed multiple factors remotely sensed nighttime light data; (4) corridors simulated extracted circuit theory. As result, our study area mainly includes 13,592 km2 sources, 8519.64 km corridors, 277 nodes. Meanwhile, framework “two axes, three belts, zones” was optimization reorganization components within ESP. Our research lays methodological practical foundation for regional construction development areas.

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.

Optimization of ecological security patterns (ESP) is an important way to implement land space restoration and maintain regional sustainable development. How comprehensively identify ESP while maintaining the balanced development each ecosystem service key issue in identification construction at present. Using data on use, meteorology, vegetation biomass socio-economic statistics, quality six typical services Shule River basin (SRB) 2010 2020 were calculated for food supply, water conservation, carbon fixation oxygen release, habitat quality, soil conservation culture leisure. The ordered weighted averaging (OWA) model was introduced priority areas as source, minimum cumulative resistance (MCR) used extract corridors nodes. Based ant colony algorithm optimal paths study area, spatial scope corridors, potential recovery points, construct optimization ESP. results show that temporal differences SRB significant, showing characteristics overall dispersion small concentration. 76 source patches with a total area 2.29 × 104 km2; 54 length 3161.87 km; 36 nodes identified. Overall, shows network complete but there still room optimization, local problems are prominent. extracted 4.21 km2, 4 points. Finally, "two two belts, three areas" determined.
