| 摘 要： | 利用已有的水文资料,分析了流沙河流域42年来降水与径流的变化,以及他们之间的相互关系。结果表明:从1959~2000年,降水量没有发生明显的变化,尤其是在干季;径流量从60年代开始减小,但在90年代后期又有所增加;径流系数有增大的趋势;降水量和径流量的年际变化幅度都有减小的趋势,径流的这种趋势更明显。各种迹象表明,除降水量的增减和季节变化外,径流量还受到其他因素(如人类活动)的影响,而且这种影响越来越大。

| Abstract: | Based on survey data during 1959-2000,the interannual variations and their trends of the Liushahe watershed mean precipitation and runoff and the relationship between the two were analyzed. The results show that there is no marked trend for precipitation from 1959 to 2000, especially in dry season. While runoff diminished from 1960s and increased from middle 1990s. And runoff coefficient has grown markedly since 1959. The amplitude of interannual variations of precipitation and runoff is on the decrease,especially runoff. Precipitation impacts runoff greatly, but the effect has lessened. So Liushahe watershed runoff has been impacted by other factors, which has been greater with time. |
