| 摘 要： | １８５５年黄河自徐淮故道在铜瓦厢决口改行清济泛道以来，在近代三角洲上历经１０次较大流路变迁。各次流路在其演变过程中均有诸多共性。文中分析了流路演变中交替产生的溯源堆积及溯源冲刷对黄河下游影响的范围，幅度和作用历时，溯源堆积与沿程堆积叠加起来对山东黄河下段的水位产生稳定性抬高。

| Abstract: | Since the Huanghe River breached its dykes at Tongwaxiang in 1855 and cha nged its cource from the Xuhuai old cource to the Qingji Flooded Cource. 10 larger avulsions have been recorded for the Delta. All these avulsions had common feat ures. This paper analyses the scope, amplitude and duration of their influence on the lower reaches of the Huanghe River produced by the retrogressive aggradation and degradation which occured alternately in the fluvial process. The retrogress ive aggradation superimposed with the aggradation down stream steadily raised the stage at the Lower Shandong Reach of the Huanghe River. |
