基于GIS的城市规划生态本底研究——以重庆市悦来生态城为例

Research on Urban Planning Ecological Background Based on GIS:A Case of Chongqing Yuelai Ecological City

采用GIS空间分析和指标统计分析相结合的方法,构建了综合分析城市生态空间格局与生态本底的研究框架。在此框架下,以重庆市悦来生态城为例,通过综合叠加各项地形、地貌分析成果选定样线,根据不同类型植物群落沿样线选取53个样方,借助GPS和GIS构建植物属性信息数据库,进而应用统计指标分析区域生态本底条件。结果显示,悦来生态城植物科属区系组成复杂,类型丰富,具备生态城建设的良好生态本底。

In this article, we use a combination method of GIS spatial analysis and statistical analysis of indicators. And we build aframework for comprehensive analysis of urban ecological spatial patterns and ecological background. Under the framework, we tookYuelai Eco-city in Chongqing as an example, selected a sample line by comprehensively superimposing topographic and geomorphological analysis results, selected53 quadrats along different types of plant communities along the sample line, plants attribute informationdatabase were constructed using GPS and GIS, and at last we analyzed regional ecological background conditions using statistical indicators. The results show that the flora of the Yanlai Eco-city is of complex composition and rich types and has a good ecological background for the construction of an eco-city.
