中文摘要：
以新疆天山北坡军塘湖河流域作为研究区，基于物理机制构建双层分布式融雪径流模型，利用研究区数字高程模型（DEM）提取流域信息，运用GIS技术与遥感技术获取积雪、植被、土壤等与融雪径流模型有关的地表信息，并结合WRF中尺度数值预报模式作为该模型气象驱动数据，对研究区融雪期进行模拟，结果显示：2009、2010年峰值模拟期间，实测与模拟径流过程线拟合度高，QR合格率分别达87％、90．85％。该模型适用性较好，对融雪洪水预警具有一定的参考价值。
英文摘要：
The Juntanghu River Basin in the north Tianshan Mountain was chosen as the study area. A double-layer distributed snowmelt runoff model based on the principle of energy balance and mass balance was developed through digital elevation model （DEM） of the study area watershed information extraction and the world soil database and the national land-use data sets for wa- tershed soil and land cover types of data. The analysis show that the measured and simulated runoff hydrograph in 2009 and 2010 fit the high QR passing rate of 87% and 90.85%. In addition, the combination of snow water equivalent changes in the value of MODIS data is verified to demonstrate the reliability of the model. The model is very useful and will provide a good ex- ample for snowmelt flood warning.
