摘要： 为渭-库河绿洲植棉土壤盐渍化的治理、改良及合理利用提供一定的理论基础和科学依据，笔者通过筛选渭-库河绿洲植棉土壤上典型的野外考察路线、GPS定点、取样测定，并对植棉土壤不同土层总盐、盐离子含量以及盐离子间进行相关性分析。研究结果表明：植棉土壤不同土层盐分含量分别：0~ 10 cm 1.555%，10~30 cm 0.454%，30~50 cm 1.082%；pH：0~10 cm pH 8.09，10~30、30~50 cm pH 8.59左右；平均含盐量分别为15.549、4.548、10.821 g/kg。不同深度土层的盐分含量从大到少顺序依次为0~ 10 cm＞30~50 cm＞10~30 cm，属于盐化土壤。相关性分析结果表明：在研究区植棉土壤不同土层的全盐量、pH、HCO3-、Cl-、Ga2+、SO42-、K++Na+、Mg2+之间的相关性基本上呈显著到极显著正相关，尤其是表层土壤中SO42-与K++Na+的相关系数达到了0.98，硫酸物在表层土壤积聚强烈，盐分以向上运行为主。

Abstract: In order to provide certain theoretical and scientific basis for the governance, improvement and rational utilization of salinization soil in Wei-Ku River oases, through the screening of typical field survey routes, GPS location, sampling and measure of cotton soil in Wei-Ku River oases, the total salt and the saline ion content were measured and the correlation of different saline ions was analyzed. The results showed that the salt content was 1.555% of 0-10 cm soil layer, 0.454% of 10-30 cm soil layer and 1.082% of 30-50 cm soil layer. The pH value was 8.09 of 0-10 cm soil layer, and around 8.59 of 10-30 and 30-50 cm soil layer. The average salt content of the three layers was 15.549, 4.548 and 10.821 g/kg, respectively. The salt content in different soil layers followed the order of 0-10 cm＞30-50 cm＞10-30 cm, and the soil belonged to saline soil. The correlation analysis showed that the correlations of the total salt content, pH, HCO3-, Cl-, Ga2 , SO42-, K Na , Mg2 in different soil layers were significantly positive or extremely and significantly positive. Particularly, the correlation coefficient of SO42- and K Na in topsoil reached 0.98. Sulfuric acid accumulated intensely in the topsoil and salt was mainly transported to topsoil.
