摘　　要：黄河下游窄河段挖河固堤启动工程于 1 997年 1 1月 2 3日在朱家屋子～清 2河段开始 ,这无疑是对黄河下游减淤途径的一种尝试。1 998年汛期对研究河段进行了水文、泥沙原型观测 ,本文主要从原型观测资料 ,分析挖河对水位、比降和河相关系等诸方面的影响。The initiative project of channel dredging and dykes strengthenning in the lower Yellow River started in the reach of Zhujiawuzi～Qing No.2 on the November 23, 1997.Without doubt, it is an attempt to reduce river deposition in lower Yellow River. The affect of river channel dredging on water level, slope, and the cross sectional shape, etc. was analyzed based on the field observation of hydrology and sedimentation in 1998 flood season.
