| Abstract: | Through measuring the groundwater buried depth,groundwater mineralization degree and total salt content in field soil during growing season of crops,the groundwater dynamic changes and the spatial distribution characteristics of soil salt content in Spring and Autumn were analyzed.The linear correlation between soil salt content and groundwater mineralization degree and the Logarithm relationship between soil salt content and groundwater buried depth were determined,and the dependent equation was established. |
