| Abstract: | Based on the analysis of characteristics of agricultural water consumption,the combined prediction model was put forward,which could effectively overcome the defect of low precision of single prediction model.And the weight ascertainment method of combined prediction model of agricultural water consumption was concluded.Finally,based on GM(1,1) model,regression prediction model and exponential smoothing model,the prediction precision of combined prediction model on Chinese agricultrual water consumption was... |
