本文通过人工模拟对黔中喀斯特白云岩地区土壤的水分入渗进行研究,分析土壤中5种不同的碎石含量(0%,20%,40% ,60%,80%)及3种不同直径(2～3mm,5mm,10 mm)的碎石对土壤渗透性的影响,研究结论认为：随着石砾含量的增加,不同容重、不同石砾含量的入渗过程,均表现为随着石砾含量的增加,先升高降低并趋于平缓,即随着时间的增加,土壤的入渗量增多然后再减少并趋于平缓.土壤入渗量在不同容重情况下,随着石砾的粒径增大,土壤的水分入渗过程是趋势大致相同.但是土壤水分的入渗过程整体上大致是先增多,然后趋于平缓,最后下降并趋于稳定.当土壤中石砾含量为 0 时,容重小的土壤渗透系数明显高于容重大的土壤,表现出容重小的土壤疏松多孔,水分容易快速入渗的特征.石砾含量为 80%时,容重对土壤水分渗透性的影响不大,土壤水分渗透系数在各砾径条件下均为最高,且下渗曲线远远高于其他石砾含量的相应曲线.石砾含量的增加会增大土壤的累积入渗量但是石砾含量非常高时累积入渗量又会降低.

Through artificial simulated to study soil in Karst dolomite area water infiltration,5 different gravel content analysis in soil (0%,20%,40%,60%,80%) and 3 kinds of different diameter (2 3mm,3 5mm,5 10 mm) of gravel on soil permeability influence,the study concluded that:with the increase of gravel content,infiltration process in different density,different gravel content,showed with the increase of gravel content,increased at first and decreased and tend to be gentle,as time increases,increase soil infiltration and then decrease and tend to be gentle.Soil infiltration under different density conditions,with the gravel particle size increased,soil water infiltration process is the same trend.But the infiltration process of soil moisture on the whole is generally increased at first,and then slowly,and finally tends to be stable and decline.When the soil gravel content is 0,the density of small soil permeability coefficient was significantly higher than that of major capacity of soil,showed a small bulk density of the soil is loose and porous,water is easy to rapid infiltration characteristics.Gravel content is 80%,the bulk density of osmotic little effect on soil moisture,soil moisture permeability coefficient in the gravel diameter conditions were the highest,the corresponding curves and infiltration curve is much higher than other gravel content.Increase of gravel content accumulation will increase soil infiltration but gravel content is very high cumulative infiltration and reduce.
