摘　　要：为了探明煤炭开采与窟野河河川径流减少甚至断流之间的关系,利用窟野河控制性水文站——温家川站1953—2010年逐日流量资料及相关水文气象资料,在对其径流变化特性进行分析的基础上,通过黄河月水量平衡模型模拟定量评价煤矿开采对地表径流的影响。结果表明:1953年以来,窟野河流域实测径流量以1979年和1999年为转折点总体上呈现阶段性减少趋势;人类活动对径流减少影响的比例由1979—1998年的39.44%快速上升到1999—2010年的56.50%,其中,煤矿开采对径流的影响量年均值在1999—2010年间达到29.69 mm,约2.58亿m3/a,成为影响窟野河地表径流减少的主导因素。In order to make clear the relationship between coal mining and runoff reduction or even drying-up of the Kuye River, China, we analyzed the variation characteristics of runoff with the daily runoff data and related hydrometeorology data from 1953 to 2010 of the Wenjiachuan station, a control hydrological station at the Kuye River. Then, the impacts of coal mining on surface runoff are quantitative simulated by using monthly water balance model of the Yellow River. The results indicate that the measured runoff data generally present a phase-decreasing trend over the last 60 years with turning points in 1979 and 1999. The runoff reduction ratio due to human activities was 39.44% during the period from 1979 to 1998, and it quickly increased to 56.50% during the period from 1999 to 2010, in which the annual average runoff value affected by coal mining reached 29.69 mm, which is equivalent to approximately 2.58×10^8 m^3/year. That is, human activities have become the dominant factor causing reduction of surface runoff in the Kuye River.
