Abstract: In order to optimize the application of the set pair analysis method, this paper improves the conventional weighting methods, such as traditional analytic hierarchy process(AHP) and entropy method, and constructs a set pair analysis model of regional water environment carrying capacity based on improved combination weighting, and applies it to the study of water environment carrying capacity in Sichuan Province.The results show that the water environment carrying capacity of Sichuan Province in 2016 is “critical bearing capacity ”,and Zigong, Luzhou, Deyang, Neijiang and Nanchong City are “weaker carrying capacity” or “ the weakest carrying capacity ”,which is the worst in all evaluated cities(prefectures).From a regional perspective, the water environment carrying capacity in southern Sichuan is the worst, followed by Chengdu plain, and Panxi area and Northeast Sichuan are relatively good.
