Resource is the basis of sustainable development. Water is the source of life. It is essential for survival and development of human beings. It is directly related to the national economy and the people's livelihood, the social development and the prosperity of nations. Disasters brought about by too little or too much water as well as water pollution restrict the sustainable development of the national economy. So it is imperative for us to solve the water problems and to carry out management of sustainable water resources (MSWR). This paper summarizes the researching status quo of MSWR, analyzes and selects the evaluation indices, and then establishes the analytical hierarchy figure. Aiming at the complexity and fuzziness of water resource system, this paper combines fuzzy theory with analytical hierarchy process and puts forward an AHP-based fuzzy evaluation approach which converts quantitative analysis into qualitative analysis. The method mainly consists of three procedures: establishment of hierarchy index-system, single-index evaluation and comprehensive evaluation. The most important procedure is the second one. In this procedure, the weights of each index and the membership degree must be calculated on the basis of AHP and fuzzy sets theory. This approach is very easy to understand and its conclusion is more accurate. Through the conclusion, problems should be found out in the water resources management. So we can take some measures to improve it.
