基于聚类分析法的江苏省城乡统筹供水规划模式研究

Research on planning mode of urban-rural regional water supply in Jiangsu province based on cluster analysis

在充分调查江苏省城乡统筹区域供水情况的基础上,分析每个供水片区水源地布局及取水规模、水厂布局及供水规模、人口密度、经济社会发展水平等特征;采用聚类分析法,以单个水源地服务面积、单个水源地服务人口和单个水源地取水规模为主要分类指标,综合考虑每个供水片区水厂数量、供水服务面积等因素,将江苏省供水规划模式分为适度集中、中度集中及高度集中供水规划模式,分析不同供水规划模式特征及适用范围;采用FISH判别分析方法,构建区域供水规划模式判别函数,为规划模式的选择提供数学函数。

Based on fully investigating the situation of urban-rural regional water supply in Jiangsu province.The characteristics of water source layout and water intake scale,water plant layout and water supply scale,population density,economic and social development level of each water supply area were analyzed.Clustering analysis method was used to service area of a single water source,service population of a single water source,water intake size of a single water source as the main classification index and considering number of water plants and Water service area in each of the water districts.Water supply planning models can be divided into appropriate concentration,moderate concentration,and highly concentration water supply planning model in Jiangsu province.The characteristics and applicable scope of different water supply planning models were analyzed.Fish discriminant analysis method was used to construct the discriminant function of regional water supply planning mode,which provided mathematical function for the selection of planning mode.
