Index system of sustainable development of regional lake water resources is put forward from four aspects (demands from mankind,demands from resources and environment, demands from economy and demands from society).

Based on the theory of sustainable development, regarding sustainable development as its aim, the significance, necessity, action, principle and function of building index system of sustainable development of lake water resources environment are discussed and the index system of sustainable development of lake water resources is built.

The characteristics of lake resources and it s development and protection on the Jianghan Lakes region;

On assessment of sustainable development level of regional water resource using artificial neural networks;

Optimal allocation model of regional water resources

Because the regional water resource is influenced by several kinds of factors with great fuzziness and uncertainty,the analytic hierarchy process was adopted to analyze each influence factor on early warning system of regional water resource for sustainable utilization.

Renewable evaluation of regional water resources based on rough set and group eigenvalue method;

Evaluation of sustainable utilization for regional water resources based on AHP and fuzzy synthetic judgment——A Case Study for Jiangmen City in Guangdong Province;

Study on analysis model of regional water resources supply and demand;

The connotations and principles of the sustainable development oriented optimal allocation to region water resources are analyzed systematically.

The connotations of region water resources system(WS )and it s sustainable development are analyzed simply;the valuating sys-tem for sustainable development of region water resources system are established,which is a hierarchy system composed of one objective hierarchy,one criterion hierarchy and two indexes hierarchy.
