摘要
根据黄河干流兰州、三门峡和花园口近80年天然径流量序列资料，分析了黄河流域天然径流量突变特征及其影响因子，并应用Yamamoto法检测黄河流域1919-1998年径流序列在年际间的突变。结果表明：黄河流域年径流量突变主要发生在1933-1935年、1969-1972年、1980-1983年、1986-1989年，气候突变是导致黄河流域天然径流量突变的直接原因。
The paper analyzes the characteristics of natural run-off mutation of the Yellow River basin and its affecting factors based on the data of about 80-year natural run-off serial of Lanzhou,Sanmenxia and Huayuankou suited on the main Yellow River and tests the interannual mutation of 1919~1998 run-off serial of the Yellow River basin by using Yamamote method.The outcomes show that the annual run-off mutation of the river basin mainly happens in the periods of 1933~1935,1969~1972,1980~1983 and 1986~1989 and climate accident is the direct reason for the natural run-off mutation of the river basin.
