Construction of Regional Ecological Network in Wenshan Prefecture Based on InVEST-MSPA
Taking Wenshan Prefecture as an example,this research combined InVEST model and MSPA to select ecological sources,used MCR model and circuit theory to extract ecological corridors and ecologi-cal nodes to construct Wenshan regional ecological network,and to identify the areas that should be protec-ted and restored in priority during development and construction.The results showed that 143 ecological sources with a total area of 5 092.74 km2 were identified,which were primarily distributed in the eastern part of Wen-shan Prefecture.The current land type was mainly woodland with high vegetation coverage and good ecological foundation.346 ecological corridors were extracted,and their spatial distribution was obvious.The corridors in the west connecting the north and middle of Wenshan Prefecture were sparse,long and easy to break.There were 1 18 ecological bottleneck points and 41 ecological barrier points that need protection and repaired.
