中文摘要	概述了2007年黄河第6次调水调沙的运行情况.从水文泥沙过程、调水调沙前后悬移质粒径变化、河道冲淤量及主槽过流能力等方面,分析研究了2007年汛前调水调沙对花园口至夹河滩段河道的影响.分析结果认为,花园口水文站来水量41.01亿m3,花园口至夹河滩河段冲沙0.041亿t,2水文站所在断面主槽过流能力增加幅度为300~500 m3/s,在流量3 000 m3/s时相应水位下降0.03~0.14 m,河段的行洪能力得到明显改善.; The course of the 2007 integrated water regulation of the Yellow River is described,then the impact of the integrated water regulation to the reach from Huayuankou station to Jiahetan station before the flood season is focused on,in terms of analyzing the hydrological process of sediment,the changed size of suspended load before and after the regulation,the scour of river flow and the ability to change the main channel,and soon.The results show that there is about 4.101�9 m3 water going through the Huayuankou hydrometric station,and about 4.1�6 tons of sediment is sent to the downstream of Jiahetan hydrometric station.The increased flow capacity of two hydrometric stations range 300 m3/s to 500 m3/s,and the corresponding stages drop 0.03~0.14 m with 3 000 m3/h flow capacity.It is obvious that the rate of sediment discharge is improved.
