In order to realize sustainable development of the arid area of Northwest China, rational water resources exploitation and optimization are primary prerequisites. Based on the essential principle of sustainable development, this paper puts forward a general idea on 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 & Produce Function Model, some standard plans of water resources optimization come into being. According to the Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environmental protection and sustainable development in Qaidam Basin is finally decided.

西北干旱区水资源的合理开发利用与优化配置是实现干旱区可持续发展目标的首要前提。论文依据可持续发展的基本原理，以柴达木盆地为例，设计了水资源优化配置的总体思路，对水资源优化配置的多目标进行竞争辨识，采用以投入产出模型、AHP法等定性为主的决策方法和以系统动力学模型、生产函数模型等定量为主的决策方法生成水资源优化配置基准方案，进而采用多目标决策方案优选的密切值模型求出了柴达木盆地宏观经济发展与水资源优化配置的最佳方案。

关键词：水资源优化配置多目标决策密切值模型区域可持续发展柴达木盆地 water resources optimization multiple targets decision by the closest value model sustainable development Qaidam Basin
