新疆焉耆盆地博斯腾湖东岸几种不同地貌单元中,盐渍土发育强烈。在研究区内自北至南50 km的地段呈线性分布。以刻槽法分5层连续采取0~1.00 m深度土壤样品,分析易溶盐含量,判断盐渍土的含盐类型。平面上,从冲洪积扇前缘的细土平原到冲积-湖积平原,盐渍化程度呈增高趋势。盐渍土的含盐类型,沙垅段主要为硫酸盐,东南岸冲积-洪积平原主要发育亚硫酸盐和硫酸盐,其余地段盐渍土类型以氯盐和亚氯盐为主。剖面上,除沙垅段外,各个地貌单元土壤盐渍化表聚性特征明显。
Saline soil is strongly developed in several different landform units on the east coast of Bosten Lake in Yanqi Basin, Xinjiang. In the study area, a linear distribution was found 50 km from north to south. The depth of 0 ~ 1.00 m soil samples were continuously sampled in 5 layers by the groove method. The soluble salt content was analyzed to determine the salt type of saline soil. In the plane, the degree of salinization increased from the fine soil plain at the front of the alluvial fan to the alluvial-lacustrine plain. The salt type of saline soil is mainly sulphate in Shalian section, sulfite and sulfate are mainly developed in alluvial-alluvial plain in the southeast bank, and the other types of saline soil are mainly chloride and chloride. In the section, in addition to sand 垅 segment, the features of soil salinization on each geomorphic unit are obvious.
