Rapid urbanization has affected ecosystem stability, and the construction of ecological security patterns (ESPs) can rationally allocate resources achieve protection. Priority evaluation critical areas maximize benefits protection, which is crucial for sustainable urban development. However, most prior studies have focused on assessing individual elements ESP, rarely considering both protection priority sources corridors. We constructed ESPs Wuhan Metropolitan Area (WMA) from 2000 to 2020 evaluated corridors The findings indicated that high-level exhibited higher overall landscape connectivity service values with lower patch fragmentation. average area proportions primary, secondary, tertiary in 2000, 2010, were 41.11%, 23.03%, 29.86%, respectively. High-level had shorter lengths offered comprehensive values. total length secondary exceeded primary by 1951.19 km, 650.39 2238.18 km 2020, Primary corridors, connected fragmented isolated sources, should their land percentage increased enhance connectivity. Secondary two independent distant providing basis intervening area, whose surrounding habitats be protected. This study identifies offers a theoretical practical reference balancing development

The continuous expansion and development of anthropogenic activities pose considerable threats to the habitats myriad species. Therefore, exploring how protect optimize species' achieve harmony between humans nature is particularly important. As a paradise for wildlife, Poyang Lake habitat breeding ground birds, fish, other aquatic organisms. In this study, adopting multi-level perspective 'point-line-area', we had an appliance conservation by constructing ecological security pattern (ESP) in Ecoregion (PYLE). We produced land use cover from 2000 2040 using random forest cellular automata-Markov model. Combining morphological spatial analysis, landscape index, Linkage Mapper, constructed long-term ESP PYLE considering protection. spatiotemporal dynamics were compared analyzed. results show that PYLE's rapid economic led extensive urban growth, encroaching on surrounding bare land, which could undermine local survival. Based predicted 2040, propose optimized 'one area, two zones, multiple points' scheme prioritize This comprehensive study provides innovative ideas novel insights future research policy formulation

Balancing socio-economic development with ecological protection amid rapid urbanization is a pressing global issue. The security pattern (ESP) follows the reciprocal relationship between and function to conserve processes, providing an effective approach address this problem. However, most studies have adopted single subjective assignment method for resistance factors, lacking exploration of impact various methods on ESP. Taking Fuzhou metropolitan area as case, study proposes different methods: favorable, moderate, unfavorable. By applying circuit theory, it constructs ESP identifies critical areas restoration. findings show that (1) cumulative threshold increases, corridors expands from 171.36 km2 1439.24 km2, moderate identified optimal approach; (2) significant differences exist in identification key under methods. 26 corridors, spanning total length 41.29 km; (3) cover 2469.79 including 13 patches pinch points, while restoration 14.55 7 barriers 21 breaking points. pinpointing proposing targeted strategies, can facilitate practical efforts, thereby achieving sustainable goal minimizing economic costs maximizing benefits.
