On the west coast of Bohai Bay, eight soil profiles have been selected in different geomorphologic units and land use, and the samples of salinized soil at 0-20, 20-40, 40-60 and 60-90 cm under the ground were collected. The soil salinized slightly in paleo-river highland, belonged to sulphate type and chloride-sulphate type of soil saline. The soil salinized moderately in influve, and been belonged to sulphate-chloride type of soil saline. The soil of super-intertidal flat is saltierra, and its salinity reach 0.7-1.1 (g/kg), and belonged to chloride type soil saline. Evaporation and eluviation of soil have been closely related with geomorphologic units and sedimentary frame. The soil of far away the sea has higher content of HCO3-, and lower content of Cl- and salinity in the same geomorphologic units.
