中文摘要：

在总结暴雨融雪混合洪水形成规律的基础上，讨论了雨雪混合产流模型结构，利用临界温度来判断降水的形式和融雪因子，同时考虑降雨引起的融雪量，结合LI-Ⅰ分布式水文模型建立一个雨雪混合洪水预报模型．利用新疆塔城地区喀浪古尔河流域暴雨融雪洪水资料进行模拟和验证．模拟和验证结果表明，预报模型具有较高的精度，其确定性系数超过0．80．

英文摘要：

Based on summarizing the rule of rainstorm and snowmelt mixed flood, the structure of rainon-snow runoff-generation is discussed; and critical temperature is used to determine the form of precipitation and snowmelt factor, taking into account rainfall volume of snowmelt. A rain-on-snow flood forecast model is developed by combining LL- I distributed hydrology model. Taking the Kalangguer River, an internal river in Xinjiang Autonomous Region, rises in the cold mountains, for example, through this case study, it is indicated that the model has a higher precision of forecasting; its determinacy coefficient is greater than 0.80.
