Abstract: In order to do a good job in the restoration and protection of the ecological environment of the Changjiang River, 4 rivers and lakes with typical characteristics, namely, the Rhine in Europe, the Thames in Britain, the Cheonggyecheon Stream in South Korea and the Lake Okeechobee in the United States, were selected as cases.The process of pollution control and the corresponding political, economic, financial and legal control measures were sorted out and summarized.In view of the similar problems existing in the ecological governance of the Changjiang River Basin, the experiences of these four rivers and lakes in cross-regional collaborative governance, cross-sectoral overall-planning management, improving legal system, strengthening public participation and commercial operations were summarized.The suggestions were put forward for China's river and lake governance and ecological environment protection in the Changjiang River Basin to establish a cross-regional joint consultation system for water pollution management in river basins, strengthen the overall management mechanism among different departments, improve the unified environmental protection legal system in river basins, public participation and other measures.This paper is conducive to the coordinated protection and development of the Changjiang River and can further improve the water ecological environment quality of the Changjiang River Basin.
