Abstract  The development of water supply network conforms to a fractal growth with selforganization property, so fractal theory can be adopted to city planning combined with water supply network partitioning. The future of the city construction and city planning was analyzed based on which the location and flow of nodes were confirmed. K-means algorithm was adopted to cluster the nodes, and analytical hierarchy process was adopted to identify the importance of the nodes in each zone. Then fractal growth of selforganization model was solved by Prim algorithm, and water supply network planning scheme was formed. The network could be managed by partitioning when it was buildup. Water distribution system planning based on fractal selfgrowth model was applied in one north city in China, and the results showed that the effect of operation and management was very well.

分形理论在城市供水管网规划中的应用研究

城市供水管网的发展符合分形自生长的特性，可以利用分形理论使管网分区与供水管网规划得到有机结合．分析城市未来建筑与市政规划，在此基础上确定城市用水户节点位置及节点流量．运用Kmeans算法对用水户进行聚类后，采用层次分析法确定各聚类区域最重要供水点，保证其优先供水．分区及供水点层次确定后运用Prim算法得到各个分区的供水管网分形自生长结构，最终形成城市供水管网规划方案．供水管网建成后可以直接进行区块化管理．基于分形的城市供水管网规划已在北方某城市得到应用，建成后管网运行与管理效果良好．
