Abstract

The taxonomic position of dry-steppe (chestnut) soils mentioned in the books Classification and Diagnostics of Soils of the USSR (1977), Classification and Diagnostics of Soils of Russia (2004), and World Reference Base for Soil Resources (2014) is discussed. Based on the example of the soils of Mongolia, it is shown that the soils of dry steppes that formed on light nonsaline parent rocks are normally nonsaline and nonsolonetzic. The soils of Mongolian dry steppes that formed on saline rocks are saline and solonetzic. The soils with profiles that include loamy layers (even those with a predominantly light granulometric composition and formed on nonsaline rocks) normally feature signs of solonetzicity in the loamy horizons.

蒙古干草原地带土壤盐分和盐碱度的表现

摘要

讨论了《苏联土壤分类和诊断》（1977），《俄罗斯土壤分类和诊断》（2004）和《世界土壤资源参考库》（2014）一书中提到的干草原（栗子）土壤的分类位置。。以蒙古国土壤为例，研究表明，在轻质非盐质母岩上形成的干草原土壤通常是非盐质和非硅酸盐岩。在盐岩上形成的蒙古干草原的土壤是盐碱化的。具有包括壤土层的剖面的土壤（即使是主要具有轻粒组成且形成在非盐岩上的土壤）通常在壤土层中也具有孤硬性的迹象。
