中文摘要	以野外调查和实地测点为基础,对新疆典型盐渍化区渭干河-库车河三角洲绿洲土壤盐分特征进行研究.分析结果表明:土壤含盐量和八大离子平均含量在三层均呈T型分布0-10cm＞10-30cm＞30-50cm,盐分表聚强烈;在不同取样深度,土壤含盐量、Cl-和Mg2+均具有较强的空间变异性,而CO23-和HCO3-在三层则均表现为中度变异性.同时Ca2+、SO24-以及K++Na+在表层表现为强变异性,在10-30cm和30-50cm土展则表现为中度变异性;通过相关性分析,发现在土壤表层,含盐量与Cl-以及K++Na+正相关关系极显著(P≥0.99),而与Ca2+和SO24-有一定的正相关性(P≥0.95);通过主成分分析,认为在该绿洲土壤系统中,土壤表层特征可用四个主要成分来体现:第一主成分代表了土壤盐化状况,第二主成分和第三主成分反映了土壤的结构状况,而第四主成分则代表了土壤的碱化特征.
英文摘要	Through a large number of field investigations and measuring sample points in the Delta Oasis of Weigan and Kuqa Rivers of Tarim Basin northern margin in Xinjiang, the characteristics of soil salinization were studied. The results indicated: the soil salt content and eight ions assume "T" in three distribution, which is 0 - 10cm ＞ 10 -30cm ＞30 -50cm. the salty chronometer gather intensely; In the different sample depth, the soil salt content, Cl- and Mg2+ have the strong spatial changeability, but CO23- and HCO3- in three performance are the moderate changeability; Simultaneously, Ca2 + , SO24- as well as K + + Na+ are the strong changeability in the surface layer performance, and the moderate changeability in 10-30cm and the 30 -50cm soil layer; the relevant analysis discovered that in the soil mantle, the total salty content and Cl- as well as K + + Na + correlation dependence is extremely remarkable (P≥0.99), has certain relevance with Ca2+ and SO24-( P≥0. 95 ); the principal components analysis showed that in this oasis soil system, the soil mantle characteristic is available by four principal constituents manifests: the first principal component represents the soil salt chemicals condition,the second principal component and the third principal component reflect the soil structure condition, but the fourth principal component represents the soil alkalize characteristic.
