摘　　要：在分析高寒山区河流水文气象特点、河道特性的基础上,探索了黑龙江冰坝的成因,计算了河槽水(冰)量、融雪径流量、融冻期降水径流量、临界冰盖强度,建立了冰坝最高水位预报模型,使以往预报方法得到了改进,并具有了物理成因理论基础,可提高预报的准确率。On the basis of analyzing the river conditions, and hydrological and meteorological characteristics in cold mountain areas, this paper discussed the cause of ice dam forming, and calculated the channel flow, snowmelt runoff and rainfall runoff. And then a model was set up a model to forecast the highest level of ice dam, so as to improve the traditional forecasting methods and increase the forecasting accuracy.

关 键 词：冰坝凌汛 河道特征 冰坝成因 预报方法 融雪径流
