中文摘要	以黑河流域上游作为典型干旱区流域，探讨了SRM（Snowmelt Runoff Model）融雪径流模型的可操作性．在论述模型结构、参数意义的基础上，重点研究以MODIS雪产品为基础的积雪面积衰减曲线的获取方法，细化了退水系数的获取，并分析了其中存在的问题．通过利用WinSRM1．10版本对黑河上游2004年融雪期进行径流量模拟，结果表明：SRM模型在以融雪水为主要补给的黑河流域上游有着较好的径流量模拟精度，拟合优度确定系数R~2为0．020，体积差Dv为7．124％．在实际应用中应最大限度利用已有的气象水文资料，以更为准确地描述融雪径流过程．针对数据稀缺的问题，需要加强小流域的观测，改进SRM模型以更适用于以融雪为主的我国西北山区流域．
英文摘要	A fitting model is necessary to simulate the snowmelt runoff process for the special regions where the water resources are supplied mostly by snowmelt and the hydro-meteorological data are sparse The maneuverability of the SRM （snowmelt runoff model） was discussed and analyzed in the upper Heihe River basin, which is regarded as the representative arid catchment in this article. The study concentrated on how to get the curves of snow coverage shrinking derived from the MODIS snow products, to calculate the recession coefficients in detail, and the existing problems were analyzed too based on the discussion about the model framework and its parameter meaning. The WinSRM version 1. 10 was utilized to simulate the runoff in the upper Heihe River basin during the snowmelt season in 2004, and the results indicated that the accuracy of the SRM is good in simulating the runoff process in the upper Heihe River basin, where the runoff is supplied mostly by snowmelt; the coefficient of determination R~2 is 0. 020, and the volume difference Dv is 7. 124%. The research indicates that the hydrometeorological data should be utilized fully and effectively in practical simulation for a more accurate description of the snowmelt runoff process; an intensive observation is necessary to solve the problems in a small basin, where the observation is sparse, so as to improve the SRM and make it better suited for the mountainous basin, where runoff is supplied mostly by snowmelt, in Northwest China.
