Abstract:: Soil salinity has a significant effect on crop growth.Analyzing the dynamic changes of soil salt content is very important in preventing the soil secondary salinization and increasing the crops outputs.Four times of field survey were conducted on typical salinized land in Yutian area,southern part of Tarim Basin and soil sampled.By means of SPSS statistical software,soil salt content and pH value were analyzed in different period in this region.Results showed that:average soil pH value is amount to 9.1,belongs to alkali soil,and large amounts of salt concentrated on topsoil;salt content and pH value of the changing trend were Sep.>May>July>March;Salt cation is mainly consisted of Na⁺,K⁺,Ca²⁺ and Mg²⁺.In March,May,July anion content in soil were Cl^->CO₃^2->SO₄^2->HCO₃^-,and chloride is most active anion,then followed by sulfate,carbonate is quite stable anion.In September, anion content in soil were HCO₃^->CO₃^2->Cl^->SO₄^2-.The correlation analysis results of salt ion in 0-20 cm soil depth indicated that there were different levels of correlations between total salt content and each salt ion in different research period (in March,May,July and Sep.).
