Abstract
The identification of key areas for ecological restoration of national land space is considered an important means for constructing an ecological security pattern and holds significant importance for maintaining ecological security and promoting the implementation of ecological restoration projects.In this paper,the Qiandongnan Miao and Dong Autonomous Prefecture of Guizhou Province was taken as the research area,and the morphological characteristics and connectivity of ecological space were analyzed by using morphological spatial pattern analysis(MSPA)and landscape connectivity assessment(Conefor).Additionally,an ecological resistance surface model was established through the analytic hierarchy process(AHP),and ecological corridors were extracted using circuit theory to identify ecological nodes as key areas for ecological restoration of national land space.The findings indicate that:① A total of 17 ecological sources have been identified,with land types primarily consisting of forest and grassland,which are concentrated in the central,northwestern,and southwestern regions,involving several national nature reserves.These areas are recognized as the core regions providing high-quality ecological space;② 34 ecological corridors have been extracted,effectively connecting the ecologically dispersed sources;③ 30 ecological pinch points and 35 ecological barrier points have been identified as key areas for ecological restoration of national land space.These results can provide a reference for ecological restoration of national land space in karst regions.关键词
