基于土地生态敏感性评价的生态产品价值分区实现研究OA北大核心CSTPCD

A beautiful ecological environment is critical to the sustainable survival and development of humans and is a prerequisite for China's ecological civilization.The sensitivity evaluation of the ecological environment in Altay City,Xinjiang,China was performed using GIS software.The results are as follows:(1)The degree of sensitivity impact on the ecological environment in Altay City is ranked from large to small:land-use type>vege-tation coverage>river buffer zone>road buffer zone>elevation>slope>aspect.(2)The overall ecological sensitivi-ty of Altay City is high.Areas with high sensitivity or above account for 42.45%of the total study area and are mainly distributed in the northern mountainous and central hilly areas and around the Ertix River.Areas with low sensitivity levels are mainly distributed in the central hills and mountainous alluvial plains.(3)Based on the eco-logical sensitivity evaluation results,Altay City is divided into three regions:ecological protection zone,ecologi-cal improvement zone,and ecological protection and governance zone.Ecological product value realization mod-els should be proposed on the basis of the characteristics of each zone,such as improving ecological compensa-tion,distinctive ecological tourism,ecological agriculture,and conducting ecological governance and restoration,providing practical reference for the realization of ecological product value in Altay City.
