Construction and Optimization of the Ecological Security of Xishuangbanna Prefecture Based on the Minimum Resistance Model
The ecological source was identified based on ecological sensitivity and hotpot in Xishuangbanna prefecture.The ecological corridors were extracted by minimum resistance model(MCR)to identify ecological node and to construct the ecological secure network of the prefecture.The results indicated that there were 21 ecological sources and 59 ecological corridors,which has frame a"four vertical and four horizontal"ecological network with a dense distribution in the southwest and a sparse distribution in the northeast.The ecological node and ecological sources and ecological buffer zones and ecological corridors altogether formed the zonal ecological secure frame.It was suggested to optimize the spatial structure.The spatial distribution of"One ring with four clusters,five vertical and five horizontal with multiple nodes"were proposed to improve the connectivity of the ecological network.
