城市总体规划生态敏感空间信息图谱的GIS构建——重庆市长寿区城市总规实证研究

生态空间控制是城市总体规划不可或缺的重要内容,也是构建生态城市的必然要求。以重庆长寿为例,利用地理信息系统与遥感技术探讨城市总体规划中生态敏感空间信息图谱的建构方法。以城市生态敏感空间识别与评价为前提,探讨了空间数据库的建设、评价指标的选择、数据处理模型构建等内容,以此为基础提出了生态敏感空间信息图谱的构建方法并叙述了详细过程。结果表明可以借助GIS和RS进行城市生态空间结构识别并构造其信息图谱,借助该图谱我们可以辅助城市总体规划进行方向性拓展决策。

The GIS Structuring of Eco-vulnerability Geo-informatic Atlas in Urban Master Planning——A Case Study of Changshou City of Chongqing

The ecological space control is the integral part of the city master plan and also the inevitable requirement of ecological city construction.With Changshou District of Chongqing City as the example,the structuring methods of ecologically sensitive space information in city master plan are explored by using the geographic information system and remote sensing technology.With the ecologically sensitive space identification and evaluation as the prerequisite,issues like the spatial database building,the selection of evaluation indicators,and the structuring of data-processing model are discussed,and the structuring methods of ecologically sensitive space information maps are put forward and the detailed process is given on this basis.The results show that the GIS and RS can be used for the identification of urban ecological space structure and structuring of its information map and the use of the map can help make directional expansion decision in the city master plan.
