以博尔塔拉河、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-、HCO3-离子具有显著相关性,精河下游河岸带土壤总盐与K+、Na+、Cl-、Mg2+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。
The contents of total salt and eight ions in soils were determined by using soils under different vegetations covered by Bortala River and Jinghe River. The results showed that the contents of total salt and salt ions in 20 cm soil layer were higher than those in the middle and lower soil layers in the surface layer of the two rivers, and the vertical distribution of soil salinity showed a strong surface aggregation. In the downstream of Bortala River There was a significant correlation between the total salts in the riparian zone and K +, Na +, Cl- and HCO3- ions. There was a significant correlation between total salts and K +, Na +, Cl- and Mg2 + ions in the riparian zone. , The lower reaches of the two rivers with chloride-based soil-based.
