Purpose To identify the ecological protection and restoration space in Shilin Yizu Autonomous County, by evaluating the importance of ecosystem services and ecological sensitivity, providing scientific basis for the implementation of ecological protection and restoration projects in the research area.
Methods Using the NPP quantitative indicator method and GIS to evaluate the importance of ecosystem services and ecological sensitivity in the study area, and the ecological protection and restoration space was recognized based on the natural ecological space scope of land spatial planning.
Results The importance of ecosystem services in the study area was normal, with extremely important areas and important areas accounting for 1.91% of the total area of the study area. The ecological sensitivity was relatively high, with extremely sensitive areas and sensitive areas accounting for 95.05% of the total area of the study area. The natural ecological space control zones could be divided into three types of spaces based on control strategy: ecological protection area, ecological restoration area, and ecological protection+ecological restoration area, accounting for 2.05%, 94.98%, and 2.97% of the natural ecological space control zones in the study area, and 1.07%, 49.57%, and 1.55% of the study area, respectively.
Conclusion By recognizing the ecological protection and restoration space in the study area, ecological restoration has been identified as a key task for the implementation of ecological system protection and restoration project in Shilin Yizu Autonomous County, a scientific approach for the implementation of ecological restoration project has been proposed, which can provides scientific basis for the ecological protection and restoration of karst areas.
