Abstract: Global temperature has being experienced a significant change characterized as warming up. It is very important to assess the impacts of temperature changes on the Yangtze River Basin. Based on the historical data from 1900 to 2000 in the Yangtze River Basin, the impact of temperature and precipitation on droughts and floods were studied. The evidences showed that the average temperature in the Yangtze River Basin increased in the last 100 years, especially in the last ten years, as the global temperature increased. The warming up mostly happened in the middle and lower of Yangtze River. The precipitation in the Yangtze River Basin increased as temperature increased and it decreased as the temperature decreased. The increase of the precipitation during the warm period increased the probability of flood, while the decrease of the temperature during the cold period increased the risk of drought in the Yangtze River Basin.

Key words: Global temperature change, Global temperature change, Yangtze River Basin, Drought, Flood, Impact
