Abstract
abstract The importance of ecological protection cannot be overlooked. Starting from the source area of the Yellow River, this study adopts a new "service-sensitive-security" assessment framework to assess the importance of ecological protection. The results showed that: (1) The areas with high ecological protection degree were distributed in the east, north and west, accounting for 73.41% of the source area. (2) Ecosystem services are mainly carbon sequestration and water conservation. (3) The main problem of ecological sensitivity is soil erosion. (4) The ecological safety zone is located in the middle of the study area, indicating that the ecological protection of the region is good, and it is necessary to continuously strengthen the protection measures to ensure the stability and sustainability of the ecosystem. The purpose of this study is to provide a reference for local and regional ecological protection and zoning improvement through the refinement of zoning through ecological protection.
