地理信息系统用于再生水管网节点水量计算

GIS Applied to Calculation of Node-flux in Recycled Water Pipeline Network

合理确定再生水管网规划节点水量是制定科学的再生水回用规划、指导城市再生水回用的基础。具体叙述了基于地理信息系统(GIS)进行节点水量的具体计算方法和步骤:辅助GIS数据库的建立,建筑量计算,管网拓扑关系建立,节点服务范围划分,各类再生水利用对象用水定额的确定等。简单介绍了应用这一计算方法对北京市门头沟新城进行节点水量的计算结果。

To determine the planned node-flux properly in the recycled water pipeline network is the base for planning and guiding the scientific reuse of that water. Specific methods and steps are described for calculation of the node-flux based on GIS, including setup of the GIS database, calculation of the work quantity, establishment of the topological relation, division of the service area of the node, determination of the rate of recycled water consumption for each user, etc., with the result from such calculation for Mentougou New City in Beijing briefly introduced.
