本文选取祁连山内陆流域， 采用多元线性回归月径流模型， 对回归系数进行了适当处理，分别得到标准化系数矩阵和径流因子矩阵， 通过矩阵元素的方向和大小来判断各参变量对径流的影响程度。结果显示， 用径流因子方法可以判断出山区流域冰川、积雪、冻土等特殊水文要素以及降水和气温在各月对径流影响的主次程度， 从而确定出影响径流的主要因子。在山区流域资料有限的情况下， 用这种方法可获得较好结果。
In this paper, we select the inland river basin of Qilian Mountains and use the multiple linear regressive monthly runoff model to properly deal with the regression coefficients, and get the normalized coefficient matrix and runoff factor matrix respectively. The influence of each parameter on the runoff can be judged by the direction and size of the matrix elements . The results show that the runoff factor method can be used to determine the major hydrological factors such as glaciers, snowpacks and permafrost in mountainous areas, and the degree of primary and secondary effects of precipitation and temperature on runoff in each month, so as to determine the main factors affecting runoff. In the case of limited data in the mountain basin, better results can be obtained with this method.
