Ecological restoration is an important part of land space governance.Under the goal of county ecologi-cal security,Taking Ningyuan in Hunan Province as an example,this paper,based on the ecosystem service func-tion of the Nanling Mountain and the characteristics of Karst Plateau landform,takes the ecological security pat-tern as the breakthrough point,spatially identifies the importance of county ecological protection,analyzes the county ecosystem problems from the overall ecological pattern,and then divides the ecological protection and res-toration zones,and proposes key ecological restoration projects.The results show that:① Ningyuan County has a high level of ecological protection importance,with 59.16％of the county's ecological protection being extremely important and important areas,and the overall ecological network protection pattern is"two screens,four rivers,multiple corridors,and multiple points";② There are many problems in the county land space,such as broken ec-ological patches,serious erosion of wildlife corridor,intensified water and soil loss,and further spread of rocky desertification risk;③ A problem oriented,zoning based,and key engineering based ecological restoration plan is in line with the formation and optimization of county-level ecological security.
