Based on the sediment discharge data of recent 60 years from the representative hydrological stations along Taohe River, both the changing law of the sediment discharge from Taohe River and the impacts from the climate change and the human activities on the sediment change are analyzed herein. The result shows that: (1) the yearly mean sediement discharge of Taohe River is 22.95 million t,while the sediement discharge starts an obvious degression along with a trend of continuous decrease from 1990; (2) significnt abrupt changes of sediment discharges occur at all the representative hydrological stations along Taohe River,while the years of the abrupt change occurred at the end of the end of the 80s and the early-medium term of 90s in the last century,for which the sediement discharge after the abrupt change is obviously decreased than that befroe the abrupt change; (3) the sediement discharge from Taohe River shows a trend of decrease under the common impact from both the climate change and the human activities. Generally,the impact from the climate change on the sediment discharge is much less than that from the human activities; i. e. the dominant role was played by the impact from the climate change on the sediment discharge before the 90s of the last century and after that is played by the human activities.
