[目的]为艾比湖地区防风治沙提供科学依据。[方法]以艾比湖流域的精河河下游河岸带土壤为研究对象,对不同植被类型覆盖条件下土壤总盐含量、八大离子等指标进行测定。[结果]研究区土壤次生盐渍化较重,总盐含量偏高,其中总盐与HCO3-、Ca2+、Mg2+、Cl-、K+、Na+含量存在较为明显的正相关关系;盐分离子按质量分数在土壤剖面基本上呈现出自上而下的垂直分异特点,盐分表聚性规律显著。在盐分组成中,阳离子以K+、Na+为主,阴离子以Cl-为主。[结论]研究区内土壤盐渍化严重,经盐渍化分级为盐土。
[Objective] The research aimed to provide a scientific basis for windbreak and sand control in the Aibi Lake. [Method] Taking the soil in the riparian zone of the lower reaches of Jinghe River in the Aibi Lake basin as the research object, the total salt content and eight ions in soils under different types of vegetation cover were measured. [Result] The secondary salinization of soil in the study area was heavy and the total salt content was high. The content of total salt had obvious positive correlation with the content of HCO3-, Ca2 +, Mg2 +, Cl-, K +, Na + In the soil profile, the fraction basically showed the top-down vertical differentiation, and the salinity table had a significant rule of polygamy. In the composition of salt, the cation is mainly K +, Na +, and the anion is mainly Cl-. [Conclusion] The soil salinization in the study area was serious, and salinization classified as saline soil.
