Based on analysis of the relationship between sustainable development and bearing capacity of regional water resources, this paper presents a fuzzy pattern recognition model and a method for qualitative assessment of sustainable development of regional water resources, which are applied to assess the sustainable development of water resources of Hanzhong Basin. The case study proves that the model and method are reliable and that results are reasonable and practicable. They can also be applied to the assessment of the sustainable development of social economies.
