摘要
针对常规GM(1,1)模型存在的不足,建立了等维新息GM(1,1)城市生活需水量预测模型。利用此模型对郑州市2010、2015和2020年的需水量预测结果分别为36003×104m3、51216×104m3和73349×104m3。
According to the deficiency of ordinary GM （ 1, 1 ） model, an information renewal GM （ 1,1 ） predicting model of urban life water demand was established. The results showed that the precision of the model was comparatively higher and its prediction error was comparatively less. The model was applied to predict the urban life water demand of 2010, 2015 and 2020 years in Zhengzhou city. 36003 × 10^4 m^3 , 51216 × 10^4m^3 and 73349 × 10^4 m^3 are needed.
