%X The construction of Danjiangkou reservoir has changed the natural water and sediment conditions. After years of operation, the riverbed in the reservoir was reformed. Previous researches only dealt with the period up to 2003. To understand the recent sedimentation in the reservoir, we calculated the sedimentation using method of section based on section data of Danjiangkou reservoir in 2003, 2009 and 2011. According to the calculation result, the sediment distribution in longitudinal, transverse and vertical directions are compared and analyzed. Results reveal that sediment deposits more at wide sections than at   narrow valleys, with the entire sedimentation rate attenuating.
