摘　　要：大气降水是土壤包气带水分补给的主要来源,然而煤炭资源的开发极易造成潜水含水层储量和土壤水含量的变化。为深入探究矿区大气降水在包气带的入渗补给过程,在位于鄂尔多斯高原中南部的新街台格庙矿区进行原位监测试验,并结合土壤物性特征测试和数值模拟等方法,开展了不同深度土壤对大气降水的响应情况以及不同大气降水强度情景下的水分入渗过程研究。结果表明,研究区包气带土壤性质决定了大气降水的运移补给过程,1 h内10 mm降水量的最大入渗深度80 cm,且在55 cm以下深度形成稳定流带,形成有效补给。Precipitation is the main source of water recharge in the soil aerated zone,but the development of coal resources causes the change of aquifer reserves and soil water content.In order to further explore the infiltration and recharge process of precipitation in the vadose aerated zone of the mining area,an in-situ monitoring test in Xinjie Taigemiao mining area in the central and southern part of the Ordos Plateau was conducted,and combined with soil physical property characteristics test and numerical simulation methods,the research on the response of soil to precipitation at different depths and the water infiltration process under different precipitation intensity scenarios was carried out.The results indicated that the soil characteristics of the aerated zone in the study area determined the transport and rechage process of precipitation,the maximum infiltration depth of 10 mm precipitation within 1 hour was 80 cm,and a stable flow zone was formed below 55 cm depth,forming effective recharge.
