Concentration ranges and characteristics of soil elements in soil(ST),soil 1B1extraction (SE) and soil solution(SS),and their relation with the element concentration in groundwater in Quzhou salt-affected area are studied in this paper.Differences between concentrations of element in SS and that in SE are influenced by water content in the soil.SE/ST ratio of each element and its average and variation coefficient in soil layers can illustrate its solubility and movement ability in a certain extent.The averages of SE in 1 m or 2 m soil profile of most of the elements are correlated significantly with mineralization and concentration of the same element in groundwater.There is no correlation ship between the concentrations in SE and in groundwater of those elements with low migration coefficient.In addition,the characteristics of vertical distribution of concentrations of elements in SE and its relations with the concentrations of elements in groundwater are described by some examples under different levels of salinity condition.
