Abstract: In order to realize sustainable development of arid area of Northwest China, rational water resources exploitation and optimization are primal prerequisites. Based on the essential principle of sustainable development, this paper puts forward the general trajectory of water resources optimization and eco-environmental protection in Qaidam Basin, and identifies the competitive multiple targets of water resources optimization. By some qualitative methods such as Input-output Model, AHP Model and some quantitative methods such as System Dynamics Model and Produce Function Model, some standard plans of water resources optimization come into being. According to Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environment protectional and sustainable development in Qaidam Basin is finally decided.
