利用天山北坡军塘湖流域2009、2010年春季融雪期季节性冻土湿度、雪深及流量数据,对春季融雪洪水与季节冻土的湿度变化进行分析,结果发现:(1)融雪期融雪洪水的流量与雪深、季节性冻土的湿度具有密切的关系,雪深及季节性冻土的湿度决定着融雪洪水峰值变化;(2)季节性冻土表层10 cm范围内湿度的变化会导致融雪洪水的产生,而10 cm以下季节性冻土的湿度剧烈变化引起融雪水的下渗而削弱了洪峰、降低了峰值。季节性冻土湿度的变化改变了下垫面的产流方式,研究季节性冻土湿度变化对融雪洪水的影响,对春节融雪洪水的预报具有重要意义。

Spring snow-melting flood and seasonal froze humidity change were analyzed based on the seasonal froze soil moisture, snow depth and runoff data from 2009 to 2012 in the Juntang River Basin in the north slope of Tianshan Mountain. The results indicate: (1) snowmelt flood flow has a close relationship with snow depth and seasonal froze soil moisture, and snowmelt flood peak depends on snow depth and seasonal froze soil moisture; (2) 10 cm range of seasonal frozen soil surface moisture will result in the generation of snowmelt flood, while seasonal froze soil below 10 cm moisture dramatic change caused snowmelt water infiltration and weaken the flood peak, lower peak. Seasonal frozen soil moisture change transforms the way of underling surface runoff, the study on effect of seasonal soil humidity change to snowmelt flood has an important significance to spring snowmelt flood forecast.
