| 摘 要： | 需水量预测的方法有很多种,但每种方法的预测结果都具有误差。在分析了回归分析法以及灰色系统GM（1,1）法的优缺点及其适用情况后,针对其缺点提出了相应的权重方法,对两种方法的预测结果进行了加权处理,并以郑州市为例进行了实例分析,分析结果表明,处理后的结果减小了预测的误差。

| Abstract: | A variety of models are applicable for water demand forecast,while each has errors in the final results.The advantages,disadvantages and applied condition of regression analysis and GM(1,1) methods.A method constructed by the two models with proper weights was proposed.A case study in Zhengzhou shows that the proposed method can reduce the forecasting errors. |
