摘要： 博尔塔拉河、精河下游河岸带不同植被覆盖下的土壤为研究对象，测定土壤中总盐与8大离子含量。结果表明: 两河下游河岸带土壤表层 、20 cm土层的总盐以及各盐分离子含量均高于中下土层，土壤盐分垂直分布呈现出较强的表聚性；博尔塔拉河下游河岸带土壤总盐与K+、Na+、Cl－、HCO-3 离子具有显著相关性，精河下游河岸带土壤总盐与K+、Na+、Cl－、Mg 2+离子具有显著相关性；经盐渍化类型判定，两河下游河岸带土壤以氯化物型为主。

Abstract: Soil samples were collected and analyzed from the riparian zone in the lower reaches of the Bortala and Jinghe rivers, the main feeding rivers of the Ebinur Lake. The pH values and the contents of total salt and 8 ions in soil under the different conditions of vegetation coverage were measured. The correlation analysis and statistical analysis were used in the study. The results showed that, under the different conditions of vegetation coverage, the total salt and ion contents in topsoil and soil at 20 cm depth were higher than those at other soil layers in riparian zone in the lower reaches of the two rivers, and salt accumulation in topsoil was significant. The results showed that there was a significant correlation between total salt and K+、Na+、Cl－、HCO-3 contents in different soil layers in the riparian zone in lower reaches of the Bortala River, and also between total salt content and K+、Na+、Cl－、Mg 2+ in soil in the riparian zone in lower reaches of the Jinghe River. Soil salinization in the riparian zone in lower reaches of the two rivers was mainly caused by accumulation of chlorides.
