重庆市水资源综合评价研究

A Comprehensive Evaluation of Water Resources in Chongqing City

以重庆市40个区县为研究对象,利用数学回归模型和地理信息系统空间插值两种方法的耦合获取重庆市各区县水资源评价的原始数据,两种方法的组合在一定程度上可提高水资源评价数据的精确性;在此基础上利用模糊物元分析方法建立区域水资源综合评价的模糊物元模型,对重庆市40个区县的水资源进行综合评价,同时利用聚类分析方法对评价结果进行验证。结果表明:重庆市水资源分布空间差异明显,水资源丰富区主要集中在研究区域的东南部和东北部,西部和中部区域水资源相对贫乏。研究结果可为研究区域合理利用水资源进行产业规划和布局提供参考。

Taking Chongqing City as a case study, this paper collects the data for a comprehensive evaluation of water resources in different counties of Chongqing by using a multi-regression analysis and spatial interpolation in GIS. This paper adopts the way of matter-element to establish the matter-element extension model for a comprehensive of evaluation of water resources in Chongqing, and the clustering analysis is used to validate the result. The results indicate that there are significant differences in the spatial distribution of water resources among different counties in Chongqing, and the districts rich in water resources focus on Southeast and Northeast Chongqing, districts less rich in water resources focus on Westward and Central Chongqing. The results serve as a basis for the industry planning in utilization of water resources.
