结合野外积水入渗试验，利用时域反射仪和中子仪进行了积水入渗条件下土壤水分动态变化的观测，并把时域反射仪和中子仪测定的土壤含水率与烘干法进行了对比；分析了入渗过程中土壤水分动态变化规律及入渗后土壤水分再分布规律
Combined with field water infiltration test, the use of time domain reflectometer and neutron meter water infiltration under the conditions of soil moisture dynamic changes observed, and the time domain reflectometer and neutron meter measured soil moisture and drying Method were compared. The dynamic changes of soil moisture during infiltration and the law of redistribution of soil moisture after infiltration
