摘    要:由于自然和人为因素作用,土壤常常呈现层状结构,这种层状结构影响土壤水分和溶质的运移特性。通过室内模拟试验,分析了层状土溶质运移特性,研究了层状土溶质运移参数变化特征。结果表明C l-在层状土及均质土中弥散度具有明显差异,并且这种差异与夹层土壤的弥散度存在密切相关。

关 键 词:层状土  土壤溶质  土壤溶质穿透曲线

Abstract:Because of the nature and human's activity,soil often takes on layered phenomena.The layered structure influence the feature of water and solute transport.According to lab simulation experiment,the feature of layered soil solute transport was analyzed,and the changes of solute transport parameter were studied.These results mentioned above shows that there are distinct differences between layered and uniform soil in dispersivity of chlorate transport and the differences result from the dispersivity of layered soil.
Keywords:layered soil  soil solute  soil solute breakthrough curve
