摘要
[目的]研究分层土壤水分运移规律,进行水分运移的数值模拟.[方法]利用Hydrus-1D软件,通过设定不同上下边界条件,进行分层土壤的水分运移模拟.[结果]利用Hydrus-1D软件可以模拟到水分运移中观测点的水头、含水量及土壤上表层流量的随时间的变化规律.[结论]水分运移中的地面边界流量、水头和含水量与降雨量的变化直接相关,科学可靠的气象数据对水分运移的模拟非常重要.
Abstract
[Objective] The aim was to study the law of soil moisture movement and conduct numerical simulation.[Method] Using Hydrus-1D software,by setting different upper and lower boundary conditions,soil movement in a layered soil was simulated.[Result] The variation law of water head,moisture content and soil upper surface flow with time was simulated by using Hydrus-lD software.[Conclusion] Surface boundary flux,water head and water content are directly related to the change of rainfall.Scientific and reliable meteorological data is very important for the simulation of water movement.
