中文摘要	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4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.结果表明:土壤平均pH值为9.1,属于碱土,盐分含量表聚强烈,土壤可溶性盐及pH的变化趋势为9月＞5月＞7月＞3月.土壤阳离子主要以Na~+,K~+,Ca~(2+)和Mg~(2+)为主.3月、5月、7月中各阴离子在土体中的含量依次为Cl~-＞CO~(2-)_3＞SO~(2-)_4＞HCO~-_3,在易溶性盐类上行过程中.以氯化盐最为活跃,硫酸盐次之,碳酸盐较稳定.而9月各阴离子在土体中的含量依次为 HCO~-_3＞CO~(2-)_3＞Cl~-＞SO~(2-)_4.0-20 cm土层中盐离子相关性分析表明,3月、5月、7月、9月各离子之间及各离子与总可溶性盐之间的相关性不同.
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.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~+,Ca~(2+) and Mg~(2+).In March,May,July anion content in soil were Cl~->CO~(2-)_3>SO~(2-)_4>HCO~-_3,and chloride is most active anion,then followed by sulfate,carbonate is quite stable anion.In September,anion content in soil were HCO~-_3 >CO~(2-)_3>Cl~->SO~(2-)_4.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.).
