The Present Situation and Hot Issues in the Salt-affected Soil Research

With the global warming,soil salinization has become a global concern in the world,and about 7% of the global land is threatened by salinity.In addition,this figure is rising.Soil salinization in China is critical,and the area of salt-affected soil is vast,which poses a great threat to agricultural development.This study summarizes the framework of the soil salinization research in China over tha past 70 years,and make comments on the inadequencies in previous studies at home and abroad.This study summarizes the present situation and future tendency of soil salinization research across the world in the last 30 years by using the literature database and data-sharing network,and identifies five research priorities and orientations for providing new ideas to carry out the saline soil research in the future.
