基于地球关键带类型的国土空间生态修复分区研究
Research on land-space ecological restoration zoning based on the types of Earth's Critical Zone:A case study of Xixia County,Henan Province
摘要
Abstract
The type units of Earth's Critical Zone reflect the characteristics of the natural background,which can provide scientific reference for the ecological restoration of land and space.We use land cover,topography and soil as the constituent elements to divide the types of Earth's Critical Zone,the regional ecological importance and ecological sensitivity are evaluated by combining the InVEST model and Conefor2.6 model,and the land-space ecological restoration zone is identified.The results show that:①The types of Earth's Critical Zone in Xixia County could be divided into 8 first-class types and 19 second-class types,with the Broadleaf forest-Hilly in the first-class types as the main type,and the Broadleaf forest-Hilly-Leaching soil in the second-class types as the main type.②The units of high ecological importance were concentrated in the central and northern parts,accounting for about 9.3%of the county.The units with high ecological sensitivity are mainly distributed in the northern hilly area.③According to the ecological level,the units of Earth's Critical Zone are divided into four categories:bottom line,tension,buffer and general,and the ecological restoration is divided into core conservation area of nature reserve,key ecological reserve,general ecological reserve and other areas.关键词
