Abstract:In order to reflect the importance of each index to evaluating irrigation areas, each index is endowed with the different weights to reflect the difference of its importance, and the accuracy of the comprehensive evaluation result also depends on the rationality of the index weight assignment. The G1 method is applied to subjective empowerment of evaluation index and the improved entropy method is applied to weight of indicators so as to meet the objectivity of the weight and guarantee that the assessment result has a certain explanation. Then the integrated method of game theory is adpted to integrate subjective and objective weights, so that the comprehensive weight of each index is obtained. The determined comprehensive weight is applied to verifying the Luohui Canal, Shaanxi large-scale gravity canal irrigation district as an example by the improved linear model. The calculation results agree with those by the extension evaluation method on the whole. With the passage of time, the evaluation level of the Luohui Canal irrigation district gradually becomes good, and the operation condition is getting better and better, which conforms to its development reality.
