| 摘 要： | 生态敏感性分析是城市规划编制研究的重要依据,运用GIS空间分析技术可以有效地实现生态敏感性定量分析。文中以环滆湖地区为研究区,选择海拔、水域、农田、水源保护区、生态保护区和建成区六项有区域代表性的生态因子,借助GIS空间缓冲区分析、叠加分析等功能,采用因子叠加取最值法得到规划研究区的总体生态敏感性区划,对研究区生态敏感性进行定量化分析与评价,为环滆湖地区的生态环境保护和空间管制规划策略制定与用地空间合理布局提供科学依据、方法支撑和决策支持。

| Abstract: | Ecological sensitivity analysis is an important basis for the study of urban planning which can effectively realize the quantitative analysis of ecological sensitivity by using GIS spatial analysis technology.This paper, taking the area of Huan''ge Lake as the study area,seleets six representative ecological factors including elevation, water area, farmland, water source protection area, ecological protection area and built-up area.With the help of GIS spatial buffer analysis, overlay analysis function, a factor superposition method is used to obtain the max or min value of overall ecological sensitivity division of planning in the study area.Through the quantitative analysis and evaluation of the study area of ecological sensitivity, it provides the scientific basis, support methods and decision support for the ecological environment protection for the space control planning strategy and land space layout. |
