摘要

利用窟野河温家川站1961—2010年的流量资料,采用滑动平均法、距平累积法分析了近50 a来径流序列的变化特征,采用Mann-Kendall检验法和滑动t检验法确定了径流序列的突变点,并将各种方法得出的径流变化特征及突变时间进行分析和对比,初步讨论造成径流变化的主要原因。结果表明,窟野河近50 a来流量明显减少,径流时间序列可以大致划分为1961—1979、1980—1998和1999—2010年3个时期,人类活动特别是21世纪以来煤炭资源的大规模开采对窟野河流量减少有重要影响。
        Based on the 1961- 2010 data of the flow in the Kuye River monitored by and stored in the Wenjiachuan Hydrologic Station,changes in runoff flow in the past 5 decades were characterized with moving average method and cumulative anomaly method and abrupt junctions in the runoff sequence identified with Mann-Kendall test method and sliding t test method. Then runoff characteristics and times of abrupt junctions worked out with various methods were analyzed and compared,and main causes triggering changes in runoff discussed preliminarily. Results show that the past 5 decades witnessed the Kuye River declining in runoff. The runoff time sequence could roughly be divided into three periods: 1961-1979,1980-1998 and 1999-2010. Human activities,especially the large-scale exploitation of coal mines early this century,has rendered a great impact on runoff in the Kuye River Valley.
