摘　　要：1986年至2000年间,黄河山东段来水来沙量较多年平均明显减少,同时引黄水量不断增加,断流时间加长,断流河段上延,在这种新的水沙条件下,山东河道的冲淤发生了新的变化。本文根据15年的实测资料,分析了连续小水对山东河道冲淤的影响并阐述了相应的治理措施。During the period of 1986-2000, the amount of input water and sediment in Shandong section of the Yellow River obviously reduced comparing the average. At the same time, the water using quantity from Yellow River continually increased, the time of zero flow lengthened and the river section of zero flow extended upwards. Under this new conditions, new change is happened to the scour and sedimentation of the river section in Shandong. According to the observed data of 15 years, this paper analyzed the influence on the scour and sedimentation by the continuous small discharge and explained the relevant improving measures.
