对安固里淖干湖区的土壤粒度组成、含盐量、含水量、有机质和p H的空间分布特征进行了研究。结果表明,湖区内土壤主要以粉粒(0.002~0.05 mm)为主,湖区外围土壤主要以粉粒(0.002~0.05 mm)、极细砂(0.05~0.1 mm)和细砂(0.1~0.25 mm)为主,湖区东部土壤比西部土壤质地更细。土壤含水量由湖区内部向外围逐渐减小,但湖岸边缘土壤含水量最高。研究区土壤盐碱化现象明显,含盐量和p H都较高,湖区东部土壤含盐量和p H都高于西部。研究区土壤有机质含量总体偏低,与西部相比,干湖区东部土壤有机质含量较高。研究区土壤含盐量、含水量与p H显著正相关,有机质含量与p H显著负相关。
The grain size distribution, salt content, water content, organic matter and p H of the soil in the dry valley of Anguili were studied. The results showed that the main soils in the lake area were silt (0.002-0.05 mm), and the outer soils in the lake area mainly consisted of silt (0.002-0.05 mm), fine sand (0.05-0.1 mm) and fine sand (0.1-0.25 mm) ), The eastern part of the lake is finer than the western one. Soil moisture decreased gradually from the inner part to the outer part of the lake, but the soil water content at the edge of the lake was the highest. The phenomenon of soil salinization was obvious in the study area, and both salt content and p H were high. Soil salinity and p H in the eastern part of the lake were higher than those in the west. Soil organic matter content in the study area is generally low, compared with the western region, soil organic matter content is relatively high in the eastern part of the dry lake. Soil salinity and water content in the study area have a significant positive correlation with p H, while organic matter content has a significant negative correlation with p H.
