| Abstract: | Using relational analysis method in grey system theory,this paper analyzes all the factors which affect water surface evaporation,selects the main factors,and establishes the multivariate linear regression forecast model between water surface evaporation and main influencing factors.Actual examples prove that this method is simple and feasible,and its forecast precision is high. |
