中文摘要	以野外调查和实地测点为基础,对新疆塔里木盆地北缘渭干河-库车河三角洲绿洲土壤特征进行研究.分析结果表明:土壤含盐量、电导率和溶解性固体在三层呈T型分布0-10 cm>10-30 cm>30-50 cm,同时,三者在各个土层均有较强的空间变异性;pH值和含水量在三层变化并不显著,pH值在各个土层为弱变异性,而含水量则表现为中等变异性;通过相关分析和主成分分析,认为以Cl~-、Na~+和Ca~(2+)为主的第一主成分代表了土壤的盐化状况,以Mg~(2+)和K~+为主的第二主成分则反映了土壤的结构状况,而以HCO_3~-为主的第三主成分代表了土壤的碱化状况.
英文摘要	Through a large number of field investigation and measuring sample points in the Delta Oasis of Weigan and Kuqa Rivers of Tarim Basin northern margin in Xinjiang, the soil salinization characteristics are studied in different spatial changes. The results show that; the soil salt content, the conductivity and the soluble solid assume T in three distribution, which is 0 -10 cm>10 - 30 cm>30- 50 cm. Simultaneously, three characteristics have the strong spatial variability in each soil layer; pH and the water content are not remarkable in three layers, pH is the weak variability, while the water content is the medium variability. The correlation analysis and the principal components analysis indicated that the first principal component which is composed of Cl~- ,Na~+ and Ca~(2+) has primarily represented the soil salinization characteristic, the second principal component which is composed of Mg~(2+) and K~+ has reflected soil structure condition, and the third principal components has represented the soil alkalize condition.
