黄河上游水沙调控的关键科学问题与研究重点

Key Scientific Themes and Research Points on Water-Sediment Regulation in the Upper Yellow River

为了促进黄河上游水沙问题的系统解决,从流域系统的角度,结合水沙灾害防治和水资源管理的实际需求,认为黄河上游水沙关键过程与调控是保障黄河上游防洪安全、用水安全和黄河长治久安的重要基础科学问题,具体包括:1风-水-重力侵蚀产沙的耦合过程;2沙漠宽谷河道冲淤过程及河床演变机理;3水库群联动调控水沙的理论与方法。研究重点包括:1沙源解析方法与黄河上游泥沙来源;2风-水-重力侵蚀产沙机理与输移过程;3沙漠宽谷河道洪-床-岸作用机理与冲淤效应;4黄河上游水库群调节与河道水沙过程的响应;5黄河上游水沙关键过程调控理论与方法。

The study of water- sediment processes and regulation approaches in the upper Yellow River are scientific needs for preventing the flood,combating water- sediment disasters,and water resources management in this area. The key scientific themes are coupling process among wind- water- gravity erosions,scouring and silting process and evolution mechanism in wide river corridor in deserts,theory and approach for regulating simultaneously reservoir group. Recent research interests are as follows： a） Approaches to retrieve sediment sources in the upper reaches of the Yellow River; b） Wind- water- gravity erosions and sediment transport; c） Interaction among flood,river bed and bank of wide river corridor in deserts,and the effects on scouring and silting; d） Regulation of reservoir group and response of water- sediment process in the river corridor for it; and e） Theory and approach for regulating key water- sediment processes in the upper Yellow River
