Abstract：Soil preparation with cave padded plastic film was implemented to ameliorate saline soil in Nanpu economic development area in Tangshan, Hebei province. In order to provide a theoretical basis for afforestation tree species selection in the coastal saline soil, the objective seedlings including Fraxinus chinensis (Fraxinus velutina Torr), Sophora japonica (Sophora japonica Linn), sabina chinensis (Sabina chinensis) and willow (Salix babylonica) were transplanted and the soil water and salt dynamic changes were continuously monitored for two years to study the effects of seedling transplantation with earth boring auger on the water and salt dynamics of coastal saline soil. It was shown that compared with the control group without transplantation, the soil moisture and electrical conductivity were reduced after seedling transplantation while the range of variation increased and the effect on the trend of soil moisture content and conductivity was not significant; the growing season and crown structure and water uptake by plant roots were the main reasons for changes of water and salt dynamics after seedling transportation, specifically, the effect of the growing season manifested that the differences of soil moisture contents of the seedlings were significant, the crown structure of seedling mainly influenced the soil moisture content of topsoil, and the water uptake by plant roots transformed the vertical distribution of the soil moisture and salic horizon. Among the four seedling species, there was no significant difference in terms of dynamics of soil moisture content, while the soil conductivities varied remarkably. The impact on soil electrical dynamics and salt rejection of sabina chinensis was the largest in the four species.
