对吐鲁番市的大河沿河、塔尔朗河、煤窑沟和黑沟上、中、下游灌区进行土样采集,测定吐鲁番市沿四条河流在非灌溉期内(3月、10月)土壤含盐量及主要离子含量,并分析土壤盐渍化类型、程度及土壤盐分与主要离子之间的相关关系。结果表明:研究区土壤有部分出现盐渍化趋势,且土壤次生盐渍化趋势较高;吐鲁番市土壤含盐量高低与各离子(即CL-、CO3-、HCO3-、SO42-、K+、Na+、Ca2+、Mg2+)含量大小有密切的关系;土壤盐分剖面分布具有表聚型;四条河流灌溉区土壤盐渍化类型的主要成分为硫酸盐渍土。 Soil sampling was carried out in the upper, middle, and lower irrigation districts of Taiheyan, Tallang, Meiyugou and Heigou of Turpan City, and the soil salinity was measured during the non-irrigation period (March and October) along four rivers in Turpan. Amount and main ion content, and analyzed the type and degree of soil salinization, and the correlation between soil salinity and main ions. The results showed that some of the soils in the study area showed the trend of salinization and the secondary salinization trend of soils was high. The content of soil salinity and the content of ions (CL-, CO3-, HCO3-, SO42-, K + , Na +, Ca2 + and Mg2 +). The distribution of soil salinity profile was clustered. The main component of soil salinization in the four river irrigation areas was sulphate saline soil.
