摘　　要：通过对黄河三个冲积性河段近 5 0年河道冲淤、水位、河势等情况的分析研究 ,综合阐述由于黄河流域不同时期水沙及边界条件的变化所引起的冲积性河道的调整特点 ,并指出现状河道普遍存在淤积萎缩、河道过洪能力下降。Based on the analyses on the deposition, erosion, water level, and river regime in the past 50 years in the Yellow River, the characteristics of alluvial river adjustment due to the changing of incoming water and sediment and river boundary in different periods in the river basin is presented in this paper.In addition,authors point out that the Yellow River faces the serious situation that river channel and flood conveyance capacity have been reducing and water level in flood period has been rising.
