基于生态敏感性分析的优化土地利用空间布局研究——以沈阳市为例

Study of Spatial Distribution Optimization of Land Use Based on Ecological Sensitivity Analysis:A Case Study of Shenyang City

通过构建生态敏感性分析指标体系,对沈阳市辖区范围内的土地利用进行单因子分析和综合分析,并在ArcGIS支持下,进行空间叠置分析,生成生态敏感性分区图。在此基础上,结合研究区的土地利用现状,因地制宜,扬长避短合理优化土地利用空间结构。为构建可持续发展的土地利用空间结构,形成环境友好型土地利用空间布局提供依据。

By constructing the index system of ecological sensitivity analysis, and by single factor analysis and comprehensive analysis of land use in the areas of Shenyang City, this paper conducts a spatial overlay analysis and creates an ecological sensitivity division map with the support of AreGIS. And on that basis, combined with the study of land use status, the paper optimizes a reasonable spatial structure of land use and provides a basis for the construction of a sustainable spatial structure of land use and an environment-friendly spatial layout of land use.
