Abstract: The paper studies the methods of the fuzzy comprehensive evaluation and the grey relation analysis to evaluate the irrigation districts.To identify the indicator weight, this paper uses the game theory to harmonize and conjugate the analytical hierarchy process and the information entropy method, minimizing the deflection between the comprehensive indicator weight and the indicator weight identified with a single method.It can eliminate the unilateral result.From the evaluation, we know that this method for identifying the indicator weight is effective, furthermore, it can be operated easily, so it fits practical use.The paper takes some typical irrigation districts in Shandong province for example, the result indicates that the array orders by using the two methods are similar, so the two methods are feasible.
