Abstract

The Dongting Lake is the second largest freshwater lake in China. In this paper, the author gives an overview on the importance of the Lake, changes in the dynamics between the Lake and the Yangtze River, new requirements of the development of the Yangtze River Economic Belt and the Dongting Lake Ecological and Economic Development Zone on the governance of the Lake. Considering the major problems in the development and protection of the Dongting Lake, the author proposes some basic ideas to protect water safety and to promote coordinated economic, social, ecological and environmental development by achieving sustainable utilization of water resources. Then he discusses why it is necessary to develop "the Great Dongting Lake Water System" and how to achieve the target. According to the principle of "Harmony between the Lake and the River, and Ecological Progress", it is important to improve the carrying capacity of water resources and water environment, and to build a golden waterway in the Lake area. The author develops a plan to build “the Great Dongting Lake Water System” of one loop, three vertical and three horizontal waterways and analyzes its important role in flood control, irrigation, water supply, navigation and ecological development.
