Salt-affected soils are extensively distributed in Northwest,North,Northeast and coastal regions in China,and large areas of arable land are salt affected as well. So they are one of the most important low-yield types of soils. Apparently under influences of human activities,their productivity is closely related to their quality. While reviewing the development of the study on salt affected soils in China,the paper analyzed the status quo of the research and recent advancement in major fields of the study,and discussed prospects of the study by referring to the frontiers and hot spots of relevant researches both at home and abroad. The paper also suggested that emphasis be laid on topics of assessment and forecast of prediction of soil salinization,soil salt-water regime and modeling,mechanism of the interaction between plant and soil salt,optimal regulation of soil salt-water regime,management and remediation of soil salinity,eco-environmental impacts of salinization,etc.
