基于GIS的北京长城文化带生态敏感性评价

GIS-based Ecological Sensitivity Assessment of Beijing’s Great Wall Cultural Belt

在国家文化公园建设背景下,国家对于大尺度线性遗产所在区域的保护工作日益重视。基于生态敏感性评价的生态区划是制定区域生态环境保护政策、规划布局的基础。文章以北京长城文化带为研究区域,选取高程、坡度、坡向、水体缓冲区、土地利用类型、植被这6个敏感性因子。利用GIS分析技术和层次分析法对北京长城文化带生态敏感性进行评价分析,并基于生态敏感性提出专项保护策略,以期为北京长城文化带的生态保护与发展提供依据。

In the context of the construction of national cul-tural parks,the state has increasingly attached importance to the protection of large-scale linear heritage areas.Eco-logical zoning based on ecological sensitivity assessment is the basis for formulating regional ecological environment protection policies and planning layout.This paper takes the Great Wall Cultural Belt in Beijing as the research area,and selects six sensitive factors,including elevation,slope,aspect,water buffer zone,land use type and vegetation.The ecological sensitivity of Beijing Great Wall Cultural Belt was evaluated and analyzed using GIS analysis technol-Aogy and analytic hierarchy process,and special protection strategies were proposed based on the ecological sensitiv-ity,in order to provide basis for the ecological protection and development of Beijing Great Wall Cultural Belt.
