尽管近二十年来水库清淤问题已越来越引起国内外泥沙工作者的关注.但平原水库的清淤问题尚少研究和试验.新疆已建成的50余座水库大部分是平原水库,有些水库已淤库容50％以上,有的已淤满失效,全省总淤积量已达11亿m~3,泥沙淤积水库的问题在全疆十分严重,但解决平原水库淤积问题的难度又比较大.由石河子农学院水利系张开泉教授等倡议并经石河子市科委组织专家论证立题的“平原水库排沙清淤问题的研 Although the problem of dredging of reservoirs has drawn more and more attention from sediment workers at home and abroad in recent two decades, there are still few studies and experiments on dredging of reservoirs in the plains. Most of the over 50 reservoirs built in Xinjiang are plain reservoirs, Some reservoirs have more than 50% sediment storage capacity, and some have gone sluggish. The total siltation volume in the province has reached 1.1 billion m3. The problem of sediment storage reservoirs in Xinjiang is very serious. However, it is difficult to solve the problem of siltation in the plain reservoirs Relatively large by the Shihezi College of Agriculture Professor Zhang Kaiquan Department of Water Resources and other initiatives proposed by Shihezi City Science and Technology Commission experts to demonstrate the subject of the "plains reservoirs Sediment Dredging Research
