中文摘要	陕北地区水资源严重短缺,定量分析窟野河流域各因素对河道径流的影响程度,对干旱半干旱地区的资源开发具有重要意义.该文首先分析了窟野河径流以及流域内降雨、气温、水保措施、用水量和煤炭开采量等因素的变化趋势;其次按照19611979年、19801998年、19992010年以及19612010年等4个时期,采用逐步回归法分别确定其显著的影响因素,求出各时期的径流相关方程,其中19612010年间的主要影响因素为降雨量、气温、水保措施和煤炭开采量;最后定量计算了19801998年和19992010年相对于基准期19611979年各因素造成的减水量,其中水保措施的减水量由65%减少到了47%,煤炭开采却增加到了19%.结果表明,采用逐步回归分析法计算的窟野河19612010年径流模拟值与实测值很接近,该方法可以在中国北方干旱半干旱地区推广.
英文摘要	There is serious shortage of water resources in northern Shaanxi region. Quantitative identification of the influences of various factors on river runoff therefore has great significance for resources development in arid and semi-arid area of China. This study firstly analyzed the change trends of the factors in the Kuye River basin from 1961 to 2010, including river runoff, rainfall, atmospheric temperature, soil and water conservation measures, water consumption and coal mines, etc. The 50 years were then divided into four sub-periods, 19611979, 19801998, 19992010 and 19612010. Using stepwise regression method, the significant influence factors and weights for each period were identified and confirmed, and the runoff correlation equation was established. Finally, compared with the base period 19611979, the water reduction of the period 19801998 and 19992010 resulted from the factors were quantitatively calculated. The water yield caused by soil and water conservation measures reduced from 65% to 47%, while the water yield caused by coal mining increased to 19%. The result showed that the simulated runoff of the Kuye River from 1961 to 2010 using stepwise regression method was very close to the measured values. This method can be used in arid and semi-arid area of northern China.
