基于MSPA和MCP模型的扶绥县生态网络构建OA

The construction of ecological network is of great significance to improve the ecological security of the county.Taking Fusui County as an example,this study used the MSPA model and landscape analysis to identify the ecological source,and then used the MCP model to extract the county's ecological corridors and identify the important ecological corridors through the gravity model,so as to construct the ecological network of Fusui County and put forward relevant optimization strategies.The results showed that:(1)There were 3 first-class ecological corridors among the 18 ecological sources in the county,which were mainly distributed in the north and south;7 second-level ecological sources and 8 third-level ecological sources were mainly distributed in the central part of the country.(2)The ecological corridors in the county formed a grid-like distribution,and the 25 important ecological corridors were mainly concentrated in the central part,and the circulation in the north-south direction was weak.(3)The county should strengthen the construction of ecological sources and corridors based on the constructed ecological network.The results of this study can provide a scientific basis for the establishment of ecological corridors and the construction of ecological networks in Fusui County.
