中文摘要	迪那河-阳霞河绿洲土壤盐渍化日益严重,直接影响当地农业发展和生态环境建设.在野外考察,GPS定点和土壤采样分析的基础上,运用统计特征值和趋势分析等方法,探讨了研究区土壤含盐量,盐分化学组成,空间分布以及电导率与各离子含量间的关系,各盐离子间的相关性等现状特征.分析结果表明:(1)研究区土壤pH值的平均值为7.46,属于中性土壤.050 cm土层盐分含量呈T型分布,010 cm土层的含盐量最大,平均值为2.10%.土体中各阳离子含量为Na++K+>Ca2+>Mg2+,阴离子含量为SO42->Cl->HCO3-,而CO32-未检出.(2)不同土地类型的盐渍化空间变异显著,果园地的盐渍化最轻,含盐量为1.04%,盐生草地的最高,为5.28%.耕地和果园地的离子含量以Na++K+和SO42-为主,其它土地类型的以Cl-,SO42-和Na++K+为主.(3)土壤含盐量与电导率有较好的相关性.总溶解固体和各离子含量之间也存在很密切的关系
英文摘要	Soil salinization has been increasing in the delta oasis of Dina and Yangxia Rivers, and it impacts directly on local agricultural development and ecological environmental construction. In this paper,by applying statistical eigenvalue and trend analysis, soil salinization of the study area, chemical composition of salt, spatial distribution features as well as the conductivity, relationship between ions and correlations between salt ions are investigated based on field work,GPS positioning and soil sampling analysis. The results show that the study area’s soil pH value is 7.46, which belongs to neutral soil. T-Distribution is shown by 0~50 cm soil salt content,0~10 cm soil salinity is the largest, while the average value is 2.10%. Each cation in soil content is Na++K+>Ca2+>Mg2+, Anion content is SO42->Cl->HCO3-, while CO32-is failed to be analyzed. Different types of land salinization have significant spatial variability, salinization of the orchard with salinity of 1.04% is the lowest, while salinization of halophytic grass land with salinity of 5.28% is the highest. The contents of Na++K+ and SO42-ions are mainly in arable land and orchard, while the contents of Cl-,SO42-and Na++K+ ions are mainly in other soil types. There is a significant correlation between total salt content and conductivity, and between total dissolve solid and soil salinity ions’ quantity
