我国水资源时空分布不均，重点经济区存在超采地下水，城市和工业发展挤占农业或生态环境用水等问题。跨流域引调水工程通过区域间水资源优化配置，以改善缺水地区的生活、生产条件和生态环境，是保障经济社会可持续性发展的重要举措。本文结合滇中引水工程规划，从调水必要性、受水区范围确定、工程规模和工程总体布局等方面，对引调水工程规划方案的优选过程进行了探讨研究。

In China, the water resources problems in key economic regions, such as the overexploitation of groundwater and the occupation of the ecological water and the agricultural water from the urban and industrial development, are induced by the uneven spatial-temporal distribution of water resources. By the optimized allocation of the water resources, the inter-basin water transfer projects have improved the living conditions and ecological environment of the water shortage region, and ensured the sustainable development of economy and society. In this paper, with the practical case of the water diversion for central area of Yunnan, the optimum process of planning scheme on water transfer project are discussed from the aspects of the necessity of water transfer, the range of intake area, the project scale and the project layout.
