Purpose Construct an ecological corridor network in Xishuangbanna Prefecture, and propose rational suggestions for regional ecological protection and restoration, ecological space management and sustainable development, and corridor composite protection.
Method Taking Xishuangbanna Prefecture as the research object, the method of “ecosystem services-ecological sensitivity” is adopted to optimize the identification of ecological source, and the minimum cumulative resistance model (“MCR Model”) is adopted to determine ecological nodes and ecological corridors. A green ecological network system is established. And taking ecological conservation as the key task, to classify multi-level ecological space management and control areas.
Result 25 ecological corridors are established within the research scope, therein 12 important ecological corridors are included. In general, the ecological corridors of the whole region extend a long distance, but their radiation area and ecological resistance are poor; important ecological corridors are divided into three lines and two types, concentrated in the central and eastern regions (belonging to Jinghong City and Mengla County respectively); the coverage of corridor is low in the southeast (Mengla County), west and southwest parts (Menghai County), the ecological node density and ecological connectivity are insufficient. Thus, there is a large space for improvement and integration.
Conclusion Xishuangbanna, as an ecological barrier on the southern border of Yunnan Province, has extremely outstanding ecological value. In response to issues such as scattered patches and multiple breakpoints in ecological corridors, it is recommended to develop a comprehensive management approach from multiple perspectives, accelerate the improvement of ecological compensation mechanisms, coordinate and regulate the corridor network, and promote the sustainable development of ecological corridors.
