中文摘要	为分析半干旱区毛乌素沙地樟子松固沙林土壤水分对降雨的动态响应特征,采用AV-3665R雨量计、ECH_2O-5土壤水分传感器、深层渗漏水量测试仪自动监测樟子松固沙林2013-2014年降雨、0-200 cm土壤含水量、200 cm以下渗漏量。结果表明:樟子松固沙林5-10月累积降雨均显著(p<0.01)影响0-200 cm层土壤水分变化,其中5-6月降雨对150 cm以下土层影响较小、9月后降雨对土壤水分补给作用显著;小于45.2 mm降雨对150 cm以下土层无直接补给作用;大于53.8 mm降雨对200 cm层土壤水分有补给作用,且表层初始含水量较高时,降雨入渗快、历时时间短、补给作用大。降雨量、土壤表层初始含水量对降雨后樟子松固沙林土壤水分入渗过程及特征有显著影响。
英文摘要	To investigate dynamic response of soil water content to rainfall in the Pinus sylvestris var.mongolicasand fixation forest of Mu Us sandy land in the semi-arid area.AV-3665R-type rain sensor,ECH_2O-5 soil moisture sensor and logger of deep soil water leakage were used to monitor rainfall,soil water in 0-200 cm layer and leakage below 200 cm depth from May to October in 2013,2014.The results showed that cumulative rainfall significantly(p<0.01)affected soil moisture in 0-200 cm layer,the rainfall in May and June had little effect on the soil layer below 150 cm depth and the effect of rainfall after September on soil water supply was significant;less than 45.2 mm rainfall had no direct recharge to the soil layer below 150 cm depth,more than 53.8 mm rainfall had a recharge effect on the soil moisture of the 200 cm layer,and when the initial surface water content was high,the rainfall infiltration was fast,the duration time was short,and the recharge effect was significant.Soil water infiltration process and characteristics of Pinus sylvestris var.mongolicasand fixation forest were significantly affected by rainfall and initial surface soil water content.
