面向数字城市总体规划生态敏感信息图谱构建的GIS方法

生态空间控制是城市总体规划的重要内容，也是构建生态城市的必然要求；数字城市规划以空间信息技术应用与空间定量分析为突出特征，探讨生态敏感信息图谱构建的信息技术方法是数字城市总体规划需要开展研究的领域。以A市城市总体规划为例，探讨基于GIS空间分析技术的生态敏感信息图谱构建方法，包括基础数据处理、生态因子确定、评价方法选择、生态敏感性评价、信息图谱构建等几个方面。实践结果表明基于G1S的城市总体规划生态敏感信息图谱构建的技术方法是可行的，可以为数字城市总体规划方案的编制提供科学依据。

Study on the Method of Constructing Ecological Sensitivity Information Map for Digital Urban Master Planning

The ecological space control is an important component of urban master planning and also an essential requirement of ecological city development. The most prominent characteristic of digital urban planning is application of spatial information technology and quantitative analysis method. Study on the information technical method of constructing ecological sensitivity information map for digital urban master planning is one of the newly research fields. Taking the urban master planning of city A as an example, the paper discussed the information technical method of constructing ecological sensitivity information map based on GIS spatial analysis. The whole process include fundamental data preparing and analyzing, ecological sensitivity indicator determining, evaluation method selecting, and ecological sensitivity information map constructing. The achievement indicated that it is possible to construct the ecological sensitivity information map for urban master plan, and it will improve the scientific characteristic for future digital urban master planning.
