大气降尘污染引起城市供水增加的污染率计量模型

Study on the pollution rate econometric model of the city water supply increasing caused by dust

分析了城市缺水及影响城市供水的诸多因素,探讨了供水影响因素与城市供水间的关系,提出了大气降尘污染因素引起的城市供水增加的污染率计算模型。在此基础上,利用该模型对西安市降尘污染引起的城市供水增加比例进行了模拟分析。该模型为城市供水预测和环境污染损失计算提供了一种可借鉴的方法,对城市环境保护及城市供水规划具有一定的参考价值。

This paper introduced some influence factors （IF） of urban water supply （UWS） and lacking of water in the city, and the relationship between IF and UWS was initially reviewed. Based on the obtained results, a pollution rate econometric model of the city water supply increasing caused by dust was presented, which has been used for the study of Xi＇an water supply system. It is though that this model could be one of the possible strategy for the forecasting of urban water supply and figuration on the loss caused by environmental pollution.
