摘　　要：介绍了供热管网的特殊性和供热管网空间数据模型的研究现状。针对供热管网数据的特点,在阐述地理网络模型的5个基本组成元素的基础上,引入供热网络的连通性规则,定义了管线和管网节点之间的复杂连接关系。再综合考虑供热管网中存在一次管网和二次管网、整个供热管网又可分为供水管网和回水管网等的特点,构建出一种有效的供热管网数据模型。最后,将构建出的数据模型成功应用于供热地理信息管理平台系统中,分别实现了对供热管网供水管网和回水管网的爆管分析,对供热管网的维护管理有重要意义。The paper has introduced the research status of heating pipe network spatial data model and the particu- larity of heating pipe network. Based on the characteristics of heating pipe network data and the five basic elements of geographical network model, connectivity rules were introduced into heating network to define the complex con- nections between the pipeline and pipe points. The heating pipe network could be divided into primary pipe network and secondary pipe network. In the meanwhile, the heating pipe network could also be divided into water supply network and return water network. Then an effective heating pipe network data model was designed. Finally, the model was successfully applied to the heating geographic information management platform system which has a- chieved the goals of the bursting analysis of the primary pipe network and secondary pipe network respectively. As a result, this system has great importance to the maintenance and management of heating pipe network.
