In order to research the water-salt dynamic of platform fields by different isolation measures in coastal argillaceous saline land of Tangshan City
the salt content and water content of platform field by different isolation measures in 2009 are analyzed.Results showed that
water-salt dynamic of platform can be divided into three stages which were salt accumulated
desalinization and resalinization.There was a negative linear correlation between the water content and salt content
from April to October
the soil salt content showed a trend of "up-down"
but the water content showed the opposite trend.The fact that the soil conductivity and water content of platform field which used isolation layer were lower than comparison platform field indicates that the isolation layer has obvious effect of salt resisting and draining.The best salt resisting isolation layer is that paved in the pattern of "double-section and a bar"
