Taking the Yeerqiang River Valley, Xinjiang as an example, types, degrees, characteristics, and causes of soil salinization were analyzed in relation to groundwater table in this district. Analysis of soil salinization degrees offered a scientific basis for agricultural development in this district; Three soil salinity composition section maps covered all the classic types of soil salinization in Xinjiang, offering reliable foundation for proposing solutions of pertinence to the problem of soil salinizaiton. Causes of soil salinization in relation with groundwater table were analyzed. On such a basis, it was pointed out that keys to controlling soil salinization is rational leaching and drainage, and build-up of an irrigation system combining open drainage ditches and the shaft irrigation wells. The study opens up new approaches to appraising and solving the problem of soil salinization in Xinjiang and other similar areas.
