中文摘要	为探讨半干旱区柠条锦鸡儿林沙丘土壤水分对降雨的响应,采用WatchDog土壤水分传感器、HOBO U30小型自动气象站同步监测毛乌素沙地人工柠条锦鸡儿林0110 cm层土壤含水量与2019年降水量,分析了沙丘土壤含水量动态变化与降雨入渗特征。结果表明:2019年5月1日9月15日期间,柠条锦鸡儿林沙丘不同土层水分含量变化受降雨量、累计降雨以及降雨入渗效应等综合因素的影响。其中050 cm层土壤含水量对降雨的响应较敏感,累计降雨46 mm可对110 cm层土壤水分进行补给;降雨量<5 mm时,湿润深度<5 cm,降雨量10 mm左右时,湿润深度<30 cm,降雨量20 mm左右时湿润深度3050 cm,降雨量30 mm时,湿润深度>50 cm,降雨量50 mm时湿润深度可达110 cm土层,说明降雨对柠条锦鸡儿林沙丘水分状况有补给作用,但是对90 cm以下土层水分状况的补给能力有限;当降雨量基本相等时,降雨强度与土壤初始含水量对入渗深度及进程有明显影响,即降雨强度越大,土壤初始含水量越高,降雨入渗深度越深,入渗历时越短。
英文摘要	In order to explore the response of soil moisture in sand dunes of Caragana korshinskii forest to rainfall in semi-arid area,the monitoring of soil moisture in 0110 cm layer and rainfall in 2019 in Artificial Caragana korshinskii forest in Mu Us sandy land was carried out simultaneously by using watchdog soil moisture sensor and HOBO small automatic weather station,and the dynamic change of soil moisture and rainfall infiltration characteristics of sand dunes were analyzed.The results show that from May 1 to September 15,2019,the change of water content in different layers of sand dunes in Caragana forest was affected by rainfall,cumulative rainfall and rainfall infiltration effect;The soil moisture content in 050 cm layer was more sensitive to rainfall;the accumulated rainfall of 46 mm could supply the soil moisture of 110 cm layer;when the rainfall is less than 5 mm,the wetting depth is less than 5 cm;when the rainfall is about 10 mm,the wetting depth is less than 30 cm;when the rainfall is about 20 mm,the wetting depth is 3050 cm;when the rainfall is 30 mm,the wetting depth is more than 50 cm;when the rainfall is 46 mm,the wetting depth can reach 110 cm soil layer,which indicates that rainfall is related to lime;the water status of sand dunes in tiaojianerlin has a supply function,but the supply ability to the soil moisture status below 90 cm is limited;when the rainfall is basically the same,the rainfall intensity and the initial soil moisture content have a significant impact on the infiltration depth and process,that is,the greater the rainfall intensity is,the higher the initial soil moisture content is,the deeper the rainfall infiltration depth is,and the shorter the infiltration duration is.
