The reservoirs’sedimentation,whcih should not be neglected in the course of reservoirs’operation,influences safety and benefit of dams.Through general investigation of sedimentation condition about a lot of reservoirs in Jiangxi province,the current condition of reservoirs sedimentation of Jiangxi province is known and grasped.In a word,the proportion of sedimentation of most reservoirs isn’t high and these reservoirs have lower deposition degree.But a few reservoirs have serious sedimentation and the quantity slowly grows.Their pollution is also serious.In order to solve the sedimentation problems,this paper put forword the measures such as forest planning,reducing construction,reservoir desilting,strengthening the management and maintenance of reservoirs.
