城市水量平衡模型分析与计算

Urban Water Balance Model Analysis

摘要:

随着城市水资源供需矛盾加大、城市给排水一体化进程的加快,水量平衡为设计和运行集成水管理提供了良好的起点.在城市水量平衡模型分析过程中,首先分层次建立了城市水系统模型,通过室内、室外、管网子系统的叠加形成城市综合水系统模型；其次从环境、经济和社务服务方面,提出了衡量城市水量的评价指标；第三,开发层次模型水量分析程序,并以SH城市水系统的原始数据为例,初步分析了SH市城市水系统中的水量问题.结果证明城市水量平衡模型的开发具有实用性和可操作性.

Abstract:

With the increasing conflicts of the urban water supply and demand,and the integration of urban water supply and water disposal,water balance is important for integrated urban water management.First,hierarchy structure was developed;the urban water system model is integrated by innerbuilding submodel,outerbuilding submodel and pipework submodel.Second,urban water performance indicators were presented and categorized to environmental,economical and social service indicators.Third,excelbased water balance program was compiled.Finally,a case study was made of SH City.Computation results show that the water balance model is practical and operable.
