Implementation of ecological product value zoning based on land ecological sensitivity assessment:Using Altay City as an example

中文摘要英文摘要

良好的生态环境是维持人类生存与发展的基础,是国家生态文明建设的重要前提.利用GIS技术对阿勒泰市的生态环境进行敏感性评价.结果表明:(1)阿勒泰市生态环境敏感性影响程度由大到小排序为:土地利用类型>植被覆盖度>河流缓冲区>道路缓冲区>高程>坡度>坡向.(2)阿勒泰市生态敏感性总体偏高,极度敏感和高度敏感等级区域占研究区总面积的42.45%,在北部山区、中部丘陵区,以及南部额尔齐斯河两岸均有分布;不敏感等级和低度敏感等级区域主要分布在中部丘陵和山间冲积平原区.(3)基于生态敏感性评价结果将阿勒泰市分生态保护区、生态提升区以及生态防护治理区3个区域,并根据区域特点提出完善生态补偿、特色生态旅游、生态农业、开展生态治理与修复等生态产品价值实现模式,为阿勒泰市生态产品价值实现提供实践参考.

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.
