The water quality monitoring revealed that the water quality in Poyang Lake is increasely degenerating in the past several years and the deterioration reasons were analyzed. The increasingly serious water pollution indicated that there were inherent drawbacks in current environmental management system of China. Therefore, the typical models of water pollution prevention and control in developed countries and China were researched. The explorations of water pollution prevention and control based on ecosystem management for Poyang Lake were reviewed, especially the practice of Mountain-River-Lake (MRL) Program in Poyang Lake Basin. At last, the challenges of water pollution prevention and control in Poyang Lake Basin was put forword such as law and policy, organization structure, participation mechanism. The researches indicated that the multiplicity and complexity of nature, humanities, society and economy in Poyang Lake determined its importance and necessity to implement ecosystem-based water environment management. In the future construction of water pollution prevention model based on integrated ecosystem management is an inevitable trend for Poyang Lake basin.
