The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.
