The water vapor transport plays an important role in the climate system. The research on water vapor transportation over Yangtze River in recent years has been reviewed in this paper. It mainly includes the basic status of water vapor transportation over Yangtze River ,the anomaly status of water vapor transportation in dry or flood years, the effects of Tibetan Plateau on water vapor transportation over Yangtze River, the correlation between water vapor transport over Tibetan Plateau and drought or flood in Yangtze River.
