Abstract: As a principal index of water resources security,the measurement of water resources carrying Capacity is an important guidance to the sustainable regional development.Taking Tongzhou District as an example,this paper establishes the evaluation index system of water resources carrying capacity based on qualitative analysis,and confirms the marginal values of each index in the critical situations.In addition,grid anatomy method of GIS was applied to construct a dataset about the index system to get objective and correct appraisal of water resources carrying capacity.Water resources carrying capacity dynamic tendency within the region was also studied by overload function of GIS and fuzzy comprehensive evaluation model.The results show the water resources carrying capacity decreases rapidly with the increase of distance from the downtown to the rural areas.Moreover,it can be predicted that the water resources carrying capacity will be high on the whole in 2020.

Key words: water resource carrying capacity, comprehensive evaluation model, geographic in-formation system (GIS), fuzzy comprehensive evaluation, Tongzhou District
