摘　　要： 枝状管网是小城镇供水管网的主要布置形式,提出了在GIS环境下构建水表、管段和开口的拓朴关系,利用抄表水量确定节点流量的方法,并针对枝状配水管网的水力计算问题,提出了一种简便快速计算的方法递归方法,分析了递归原理、链式表的建立以及递归算法的具体实现等。实践证明该方法对提高城镇输配水管网的水力计算精度高,有较大的应用价值。 Tree-structure is a main way of distribution pipeline in small towns and townships. In this paper, we present a simple and convenient calculation modelreeursive algorithm for hydraulic computation of tree structure distribution pipe network, which establishes the topological relationship between water meters, pipe lines and openings under the GIS （Geographic Information System） environment, and analyzes the node discharge according to the volume measured. The principle of recursive algorithm, the chain list, and the realization ways are presented also. Meanwhile, an example is given, and the model is proved to have high application value for the hydraulic computation of tree-structure distribution pipe network in small towns and cities with high accuracy.
