摘　　要：针对当前排水管网拓扑模型简单、拓扑分析能力较弱的现状,提出了一种管网拓扑精细模型,改进了节点单一问题,将节点细分为多类并提出相应的拓扑规则,使之更符合管线客观模型,有利于进行空间分析。在管线和节点数据结构设计中,采用十字链表作为管网数据结构,便于管线与节点双向分析,同时建立R树索引,实现对空间数据管理。结合镇江管网地理信息系统开发实验,实现了基于改进拓扑模型的空间分析算法,结果发现本文提出的拓扑模型结构简单,易于实现,能够模拟管线排水细节,提供更多基于水务模型的空间分析类型,数据访问效率较高。For the problem of simple topological model and weak topological analysis,a fine topology model of pipe network was proposed,which improved the problem of junction simplifed,subdivided the junction into more classes and proposed corresponding topology rules to make it more in line with the objective model of pipeline,thus helpful for spacial analysis.In the pipeline and junction data structure design,orthogonal list was proposed for pipe network data structure,to facilitate pipeline and junction two-way analysis,as well as R-tree index was established to achieve spatial data management.Combining with the development of Zhenjiang pipe network GIS,the spacial analysis algorithm based on the improved topological model was realized,it shows that the topology model presented in this paper is simple and easy to implement,and can simulate the details of pipeline drainage and provides more spatial analysis types based on water model,moreover,the modle is with high efficiency.
