中文摘要	融雪水土壤入渗量是干旱区沙漠重要的水平衡收入项.20122013、20132014年两个冬季对古尔班通古特沙漠南缘沙丘西坡、东坡和丘间地降雪前和融雪后的土壤含水率进行监测,根据水量平衡原理计算了沙丘西坡、东坡、丘间地和景观尺度上的融雪水土壤入渗量,并与采用筒测法的实测结果进行比较.结果表明:降雪前土壤含水率较低,未冻层非饱和土壤水对地表冻结层土壤水分的补给可忽略不计;融雪入渗水是表层土壤获得补给的主要水源;冻结期潜水既没有蒸发,积雪融化后潜水也没有获得补给;研究区西坡、东坡、丘间地和景观尺度上的融雪水土壤入渗量分别为20~43、27~43、32~45和26~45 mm.
英文摘要	Soil infiltration of snow-melt water is an important income item of water balance in arid desert. The soil water content in west slope,east slope and interdune of sand dune in the southern Gurbantunggut Desert was monitored before snowfall and after snow melting during the winters of 2012 - 2013 and 2013 - 2014. According to the principle of water balance,soil infiltration of snowmelt in the west slope,east slope,interdune and landscape scale was calculated,and compared with the results measured by cylinder method. The results showed that the soil moisture recharge from unfrozen layer of unsaturated soil to surface frozen soil was negligible because the soil moisture content before snowfall was lower,soil infiltration of snow-melt water was the main source of soil water of shallow soil,phreatic water did not evaporate during freezing period,and did not get recharge after the snow melting. Snowmelt water in the west slope,east slope,interdune and landscape scale were 20 - 43,27 - 43,32 - 45,26 - 45 mm,respectively.
