中文摘要	运用经典统计学和冗余分析方法, 对玛纳斯河流域绿洲土壤全盐量(TS)、pH、电导率(EC)、钠吸附比(SAR)和盐分离子组成的空间分布特征进行了分析。结果表明:土壤全盐量呈现明显的底聚特征, 各层土壤全盐量均值在5.80~9.02 g·kg~(-1), 表现为轻度至中度盐化;各层土壤中, pH在8.2~8.4、EC在0.70~1.38mS·cm~(-1)、SAR在0.25~0.64, 未出现碱化现象。冗余分析表明:不同层次土壤中, Ca~(2+)与SO_4~(2-)、Na~+与SO_4(2-)保持较好的关联性。TS的空间分布, 在0~70cm全剖面上主要受控于Na~+、SO_4~~(2-)、Ca~(2+)和Mg~(2+);分层与全剖面的情况略有不同, 但Na~+、SO_4(2-)在各个土层仍为最主要的控制离子。EC在全剖面上的空间分布受控于Na~+、SO_4~(2-);50~70cm土层主要受Na~+与Cl~-的控制, 其他土层与全剖面相同。pH受控于CO_3~(2-);除0~10cm土层受HCO_3~-影响外, 其他土层与全剖面相同。SAR在全剖面的空间分布受环境因子的影响较小, 除50~70cm土层受Cl~-因子的制约外, 0~50cm土层未表现出明显的控制因子。
英文摘要	In this paper, the conventional statistics and redundancy analysis were used to investigate the spatial distribution of total salt content (TS), pH value, electrical conductivity (EC), sodium adsorption ratio (SAR)and ion composition of salty soil in the Manas River Basin, Xinjiang, China. Results are as follows: (1)The soil salt content varied in a range from 5. 80 g·kg~(-1)to 9. 02 g·kg~(-1), soil salt accumulation occurred in subsoil, slight or moderate salinization occurred in soil layer, that is the slight soil salinization occurred in topsoil (0-10cm)and moderate one in subsoil (20-70cm); (2)pH value, EC and SAR in whole soil profile varied in ranges of 8. 2-8. 4, 0. 70-1. 38 mS·cm~(-1)and 0. 25-0. 64 respectively, so alkalization did not occur; (3)Ca~(2+)and SO_4~(2-), Na~+ and SO_4~(2-)were good relationships in whole soil layer; (4)SO_4~(2-), Na~+, Ca~(2+)and Mg~(2+)were the main factors affecting the spatial distribution of total soil salt content throughout soil profile. Although there was a slight variation of their contents, SO_4~(2-)and Na~+ were still the main factors; (5)The spatial distribution of EC in the whole soil profile was restricted by SO_4~(2-)and Na~+, except in soil layers where Na~+ and Cl~-were the dominant factors; (6)Except the pH value in soil layer of 0-10cm in depth was affected by HCO_3~-, the pH value in the whole profile was mainly affected by CO_3~(2-); (7)The effect of environmental factors on SAR was slight, except SAR in soil layer of 50-70cm in depth was affected by Cl~-, there were no the dominant factors for soil layer of 0-50cm.
