Abstract: The trends of water flow and sediment changes at thre e hydrographic stations (Pingshan, Beibei and Yichang) in recent 50 years are an alysed. The analytic results show as follows: The variation of average annual runoff of the upstream of the Yangtze River is not distinct, while the sediment delivery rate has been reduced gradually. The sediment discharge at Pinshan Hydr ological Station was rather high from 1980 to 2000, but presented a decreasing t rend from 2001 to 2005. The change trend of water flow and sediment at Beibei Hy drological Station was completely consistent, while the sediment delivery rate w as reduced very obvious. The sediment outflow at Yichang Hydrological Station ha s presented the downward trend since 1980s, specially was reduced severely sinc e 1990s.
