摘要/Abstract

摘要： 利用EOS/MODIS卫星资料和气象水文台站观测资料,对2002-2008年库玛拉克河流域融雪期的洪水成因、积雪变化与气象因子的相互关系以及混合型和融雪型洪水的天气特性等进行了分析。结果表明:① 库玛拉克河7月中旬至8月中旬洪水的主要成因是高温融雪;② 夏季0 ℃层高度的变化可作为融雪型洪水预测的较好指标;③ 盛夏库玛拉克河流域以融雪型洪水为主。

Abstract: Base on the information of satellite observation (EOS/MODIS) and the meteorological and hydrological data observed by the meteorological and hydrological stations in the Kumalak River Basin, this paper analyzes the formation causes of snowmelt flood and the relations between the change of snow cover depth and the meteorological factors in the Kumalak River Basin during the period of 2002-2008, and studies the weather system and the meteorological factors resulting in the mixed and snowmelt flood in the drainage basin. The results show that snowmelt caused by high temperature is the cause of flood during the period from mid-July to mid-August. The change of 0 ℃-level height over the drainage basin in summer can be regarded as a good index of predicting flood. Snowmelt flood in midsummer is dominant in the Kumalak River Basin.
