依据黄家河水文站实测资料,对其降水量、径流量、输沙量进行了统计分析,得出了1981~1985年、2001~2005年降水量较丰,1991~1995、1996~2000年径流量较丰,输沙量亦大;2006~2010年降水量减少趋势显著,径流量、输沙量减少很大。
Based on the measured data of Huangjiahe Hydrometric Station, the precipitation, runoff and sediment load were statistically analyzed. From 1981 to 1985, the precipitation from 2001 to 2005 was quite abundant, and the runoff from 1991 to 1995 and from 1996 to 2000 The abundance of sediment and the amount of sediment were also large. The precipitation decreased significantly from 2006 to 2010, and the runoff and sediment discharge decreased greatly.
