| 摘 要： | 以天山北坡军塘湖流域为研究区，测量2009年和2010年该地区不同深度土壤湿度的变化，并对2 a融雪期各土壤湿度进行比较。结果表明：2 a间 0 cm和10 cm土壤湿度变化趋势一致，20 cm和30 cm土壤湿度变化差异较大。运用相关分析方法，分析2009年各层土壤湿度与2 m气温、土壤温度及雪深的关系，得出各层土壤湿度变化是气温、雪深和土壤温度综合作用的结果，但在不同时期不同深度土壤湿度所受的影响因子不同。同时分析了2009年和2010年不同土壤湿度特征与融雪洪水洪峰的关系，得出在融雪期，若下层（20 cm以下）土壤湿度变化小则出现洪水，反之则无洪水。其结果为进一步研究融雪径流模型和洪水径流预报提供基础资料。

| Abstract: | In this paper,soil humidity values were measured in the Juntang River Basin in northern slope of the Tianshan Mountains in 2009 and 2010 to study the change trend of soil humidity and compare soil humidity in snow melting season.The results show that the change trend of soil humidity was similar at soil depth from 0 cm to 40 cm in the study area,but its difference at soil depths of 20 cm and 30 cm was quite different.Correlation analysis was used to analyze the relationships between the soil humidity and the soil temperature at depth of 0-40 cm,air temperature at 2 m height and snow cover depth.The results reveal that soil humidity at different depths is jointly affected by air temperature,snow cover depth and soil temperature,but the main factor affecting soil humidity is difference from different soil layers.Moreover,the relationship between soil humidity and snow-melting flood peak in 2009 and 2010 was also analyzed,and the results revel that a flood may occur if the change of soil humidity below 20 cm was low,on the contrary,there was no flood if the change of soil humidity was high.The study results can be referred in the further study on developing snow melting runoff models and predicting snow-melting flood. |
