Abstract
In view of the problems such as the single result of existing ecological restoration zoning and the lack of refined guidance,taking Hantai District in Hanzhong City as the research area,we developed a 3D ecological restoration zoning model based on natural resource background,leading ecological function,and ecological restoration potential.We analyzed the natural resource background such as the regional terrain conditions,basin distribution,and vegetation types to delimit the ecological restoration regions at first.Then,based on the evaluation results of ecosystem service functions such as biodiversity,water conservation,soil and water conservation,carbon sink function and food security,we delimited the ecological restoration sub-regions.Finally,by integrating restoration potential indicators such as soil erosion,farmland management,river and lake wetlands,ecological degradation,and ecosystem resilience,we delimited the ecological restoration units.Hantai District was divided into 3 restoration regions,5 restoration sub-regions and 10 ecological restoration units with corresponding proposed strategies.The research result can provide reference for ecological restoration practice in Hantai District and technical reference for ecological restoration zoning in other regions.关键词
