The influences of mineralization degree on infiltration characteristics of coastal saline soil and brown soil were investigated by an indoor experiment of one-dimensional water ponding infiltration,using infiltration duration,infiltration rate,accumulative infiltration and average water content increment as indexes.Results show that compared with fresh water,saline water increased soil infiltration ability significantly.The abilities for the two soils reached the highest value as the mineralization were 12and 3g/L,respectively.As wetting front reached 25cm,infiltration duration for saline water was less than that for fresh water by 32.5% and 38.2%.Under the same mineralization degree,the infiltration ability for saline soil was usually stronger than that for the brown soil.Under the different mineralization,however,the infiltration ability for the saline soil did not show a big difference.Philip model could accurately simulate the infiltration process for the short-duration salty water and the deviation was within the range of±0.19%.With different mineralization degree levels water,the mean water content increment for the saline soil varied between 36.64% and 37.82%,while that for the brown soil ranged from 36.64%to 37.82%.
