| According to water consumption characteristics of Weihe River basin and the idea of system engineering,an index system of water utilization level assessment was established for the basin,and the steps and methods to determine the index weights based on AHP was studied.Meanwhile,discussion and analysis were also made on key problems of optimal index set,index set standardization,grey relation coefficient and judgment result matrix in multilayer grey relation comprehensive evaluation.Then a water utilization level evaluation system of C/S mode was developed by using VC++ program language and database technology,which was validated with water utilization data of the typical area in the basin from 2003 to 2005.The results showed that the evaluation results are consistent with actual situation,and this research method has a certain value for generalization. |
