Abstract: In order to measure the effect of the grassland ecological compensation policy in the Yili River Valley, an evaluation index system was constructed, and the AHP-Fuzzy comprehensive evaluation method was used to evaluate the ecological, economic and social benefits. The results showed that the evaluation indexes of ecological and social benefits of the Yili River Valley were 7.54 and 7.34 respectively, both of which were in the second level and the effect was good; the economic benefit evaluation index is 5.94, which is in the third level, and the effect was average; the comprehensive benefit evaluation index it is 7.01, which was in the second level, and the effect was good. The problems in the process of policy implementation was analyzed, and some policy recommendations were put forward, including raising the compensation standard, adjusting the compensation payment time, strengthening policy supervision, improving the quality of herders,and speeding up the transformation of herders’ production methods.
