摘　　要：黄河下游河道滩区防洪形势的严峻性使下游滩区的治理受到广泛关注.针对这种现状,作者搜集整理黄河下游各大断面历年汛期实测资料以及断面资料,用Visual FoxPro程序建立数据库;采用断面法计算汛期特征断面冲淤量;通过分析各断面历年汛期冲淤面积和平均冲淤深度变化,分析了近50 a不同来水来沙条件下河道冲淤演变特点,得到不同来水来沙对河道冲淤影响的几点认识.Because the flood control situation of the lower Yellow River is pregnant with grim possibilities, the fathering of the flood-plain is attracted widespread attention. In view of this situation, the authors collect many measured data of the characteristic sections of the Lower Yellow River in the flood season; and then set up the database by using Visual FoxPro. The erosion and the deposition values of the characteristic sections are calculated by using the cross-section method. Through analyzing the change of the cross-section area of erosion and deposition and the average depth of erosion and deposition in the flood season, some views about the erosion and deposition change of the channel under different conditions of the water and sediment, are obtained.
