It’s necessary to assessment the regional water resources carrying capacity for water resources long-term plan and projects. In this paper, the water supply and water utilization of Heze City in the past 10 years are analyzed firstly, and then figured out the current situation and existing problems of water resources in this study area. Thirdly, on the basis of constructing the comprehensive evaluation index system of water resources carrying capacity of Heze City, we introduced a fuzzy comprehensive evaluation model of water resources carrying capacity of Heze City. The purpose is tantamount to dynamically evaluate and analyze the water resources carrying capacity of the current level year and the planning level year of Heze City. The result showed that the water resources carrying capacity level of Heze City are changing to a positive direction, but the trend is weak and the prospect is not optimistic. At the same time, the validity and feasibility of the model and method are verified.
