以西宁市供水量各规划水平年值为基础，在分析原始数据序列的基础上，进行供水量的预测模型研究。提出两种供水量预测方法，即一元线性回归模型及灰色预测模型，并分别进行了实例计算与分析，同时与西宁市规划部门供水量预测值进行了比较。研究结果表明，灰色预测模型较一元线性回归模型为优，可作为西宁市规划水平年的供水量预测模型
Based on the annual values of water supply in each city in Xining City, based on the analysis of the original data series, the prediction model of water supply was studied. Two water supply forecasting methods are proposed, namely the one-dimensional linear regression model and the grey forecasting model, and the examples are calculated and analyzed respectively. At the same time, the water supply forecasting values of the planning department of Xining City are compared. The research results show that the grey forecasting model is superior to the one-dimensional linear regression model and can be used as the water supply forecasting model for the planning year of Xining City.
