Identifying Key Areas of Green Space for Ecological Restoration Based on Ecological Security Patterns in Fujian Province, China

Urban expansion has resulted in the fragmentation of green spaces. Based on concept a living community that integrates mountains, rivers, forests, farmlands, lakes, and grasslands, extraction key elements spaces regional ecosystems provides core scientific support for ecological restoration territorial According to service function importance sensitivity, sources were identified this study. Furthermore, we distinguished corridors using minimum cumulative resistance (MCR) model areas circuit theory model. The result showed (1) 62 present with total area 4696 km2, which space accounted 98.19%; meanwhile, 151 (optimal path) densely distributed southwest region around Daimao Bopingling mountains. (2) study included 17 19 corridors. covered by pinch points was 1327 among 77.54% comprised forest area. barriers 9647 still highest proportion (63.92%). (3) comprehensive analysis spatial distribution spaces, formulated classified measures. findings are expected provide reference planning
