Experiments show that for the same dry density, permeability decreases with the saline content; for the same soil, with increase in saline content, permeability of soils with sodium sulphate decreases more significantly than that with sodium chloride.

• 结果表明：在干容重相同的情况下，渗透系数随着含盐量的增加而减小；对同一类型土，随着含盐量的增加，硫酸盐土的渗透系数要比氯盐土渗透系数减小显著；在干容重和盐类相同的情况下，细颗粒含盐土的渗透系数要比粗颗粒含盐土的渗透系数减小显著。
