摘要： 黄河下游河川年径流量有逐年减少的趋势,花园口站90年代实测年径流量为80年代的65.1%,这与上中游年降水量减少、用水量增加有关。河川年最大流量逐年减少,花园口站90年代平均最大流量为80年代的68.6%,并出现了“小流量、高水位、大漫滩”的发展态势。河川小流量或断流日趋严重,利津站90年代累计断流天数为80年代的8.2倍,文中分析了缓解其影响的可行对策。

关键词: 黄河下游, 径流, 趋势, 对策

Abstract: The annual runoff at the lower reaches of the Huanghe River appears a decline tendency year by year, which is related to annual drop of precipitation and rise of water consumption at the upper middle reaches of the river. The ratio of the measured annual runoff between the 1990s and the 1980s was 65.1% at Huayuankou Station. The annual maximum discharge in the river also shows an annual reducing tendency and the situation of higher water level accompanied with smaller discharge but bigger flood threat has occurred. The ratio of the average maximum discharge between the 1990s and the 1980s was 68.6% at Huayuankou Station. The small discharge or absence of flow in the river shows an annual increasing tendency, in which the ratio of the cumulative days with absence of flow in the 1990s to that in the 1980s was 8.2 to 1 at Lijin Station. The feasible countermeasures for reducing the effects of absence of flow in the river were analyzed in this paper.

Key words: lower reaches of the Huanghe River, runoff, tendency, countermeasures
