中文摘要	土壤含盐量对作物的生长有较大影响，分析土壤盐分动态变化对防止土壤次生盐渍化和提高农作物产量有较大意义。对塔里木盆地南缘克里雅河流域于田地区典型盐渍化地进行两次野外调研，在GPS定点，土壤采样及室内分析的基础上，借助Excel、SPSS等统计软件对研究区不同时期土壤含量盐及pH进行比较。分析结果表明：土壤平均pH为9．18，属于碱土，盐分含量表聚强烈，同3月比较，5月土壤剖面盐分含量及pH呈上升趋势。土壤阳离子主要以Na~＋、K~＋、Ca~(2＋)、和Mg~(2＋)为主，各阴离子在土体中的含量依次为C1~-〉CO_3~-〉SO_3~(2-)〉HCO_3~-，以氯化盐最为活跃，硫酸盐次之，碳酸盐较稳定。以0-20cm为例对盐离子进行相关性分析可知，3月和5月各离子之间及各离子与总可溶性盐之间的相关性水平不同。
英文摘要	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. Field survey was conducted for two times on typical salinized land in Yutian area, southern part of Tarim Basin. 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 9.18, belongs to alkali soil, large amounts of salt concentrated on topsoil; in May, salt content and pH value in soil profile were higher and appeared increasing trend compared with that in March at the same site; Salt cation mainly consists of Na~＋ .K~＋ .Ca~(2＋) .and 1VIg~(2＋) ,and chloride is most active anion, then followed by sulfate, carbonate is quite stable one. The correlation analysis results of salt ion in soil 0 - 20 cm depth indicated that there were different levels of correlations between total salt content and each salt ion in different research period（in May and March） .
