基于GIS的城市密集区生态空间测度及评价研究——以武鄂黄黄都市连绵区为例

A Research on the GIS-based Measurement and Evaluation of the Ecological Space in Densely Urbanized Region——Wu-E-Huang-Huang Metropolitan Interlocking Region as An Example

城市密集区生态空间在区域发展中有着非常重要的作用,对城市密集区生态空间测度及评价方法的探索,旨在为城市密集区生态空间规划提供科学有效的依据。以武鄂黄黄都市连绵区为研究对象,选取区位指数、土地现状、地形条件(高程、坡度)、水文条件(河流、湖泊)、景观价值、道路交通六大类作为生态因子,运用GIS软件分别采取单因子评价和多因子综合评价的方法,对武鄂黄黄都市连绵区生态空间状况进行测度评价。按照测度的结果,将区域的生态环境按生态敏感性分为高敏感区、敏感区、弱敏感区和不敏感区4个等级,并在此基础上指出区域生态空间存在的问题。

The ecological space in densely urbanized region plays a very important role in regional development. Exploring the measurement and evaluation method of the ecological space in densely urbanized region is aimed at providing scientific and effective basis for ecological space planning in densely urbanized region. Taking Wu-E-Huang-Huang Metropolitan Interlocking Region as the research object, the paper selects six categories of impact factors as ecological factors, mainly including location index, land status, terrain condition（elevation and slope）, hydrological conditions（rivers and lakes）, landscape value and road traffic. Taking a single factor evaluation and multi-factor comprehensive evaluation method in GIS, the paper makes measurement evaluation for the ecological space conditions of Wu-E-Huang-Huang Metropolitan Interlocking Region. According to the result of the measurement, the ecological environment of region is divided into four levels of the highly sensitive area, sensitive area, less sensitive area and insensitive area. And on this basis, the problem of the status of regional ecological space will be indicated.
