Abstract: At present, the systems of comprehensive utilization of water resources and comprehensive disaster prevention and reduction have been basically formed in the Yangtze River Basin, and the framework of water environment improvement and water ecological protection and governance has been preliminarily established. Nevertheless, the Great Protection of Yangtze River and the high-quality development of the Yangtze River Economic Belt in the new era pose new requirements while shortcomings still exist. In the present paper, we probed into current existing problems, including extensive water usage, severe waste water discharge, declining aquatic biodiversity, and frequent local floods and droughts. According to the integrity, systematicness and inherent law of the Yangtze River water system, we put forward strategies and coordinated governance approaches for four water problems: water environment deterioration, water ecology damage, water resources shortage, and flood and drought disasters.
