摘要
根据祖厉河干流代表水文站会宁、郭城驿、靖远1955—2012年的降水、输沙量资料,分析了祖厉河输沙量变化规律,以及气候变化和人类活动对祖厉河输沙量变化的影响。结果表明,1955—2012年祖厉河输沙量显著减少并仍呈减少趋势,气候变化对输沙量减少的影响很小,人类活动起主导作用,2000年以来人类活动对输沙量减少的影响呈减弱趋势。
The paper analyzed the variation law of sediment discharge and the influence of climate change and human activities to the sediment discharge of Zuli River based on rainfall and sediment discharge of representative hydrological station of Huining,Guochengyi,Jingyuan of main stream of Zuli River. The outcomes show that the sediment discharge is obviously decreased and still show declining trend from 1955 to 2012.The influence of climate change to the decrease of sediment discharge is very small. The human activities play a leading role in sediment discharge and since 2000,the influence of human activities to the decrease of sediment discharge shows declining trend.
