Abstract:The construction of wildlife migration ecological corridor helps to eliminate the impact of landscape fragmentation on biodiversity and maintain the structural integrity and functional stability of the ecosystem. This study takes the elk population in the middle reaches of the Yangtze River as the research object, constructs its potential ecology through the minimum cumulative resistance model, and discusses the habitat connectivity of the elk ecological corridor in the middle reaches of the Yangtze River.The results show that the existing habitats of milu deer in this area are concentrated in Hunan milu deer distribution area, fuxingzhou distribution area, tuer distribution area, yangbotan distribution area, nanfuwan distribution area, shenhuangzhou distribution area, sanhehuan distribution area and Shishou milu deer distribution area.The potential ecological corridor has the characteristics of low altitude, gentle slope, near water source and far away population.Therefore, in the process of building ecological corridors, the selection of corridors must be based on the ecological principle of respecting the actual habitat conditions and wild animals, select the best ecological area for the ecological function area of the migration and diffusion of a species, optimize the landscape structure, strengthen the construction of ecological functions, and maintain the stability and virtuous cycle of biodiversity.
