土壤地球化学是研究成土风化壳和土壤的化学组成、元素迁移、分异及形成的过程。通过对表层岩石、土壤、天然水、有机体中元素的富集和分散的自然规律的分析,能更深刻地揭露植被、土壤及潜水元素之间的内在联系,对了解古地理土壤形成环境,土壤肥力发展方向,确立环境本底值有十分重要的意义。本文主要阐述乌兰布和沙漠土壤地球化学的特征及类型,为制定分区利用规划提供科学依据。
Soil geochemistry is the study of the weathering crust and soil chemical composition, element migration, differentiation and formation process. By analyzing the natural laws of enrichment and dispersion of surface rocks, soils, natural water and organic matter, we can reveal the intrinsic relationship between vegetation, soil and submerged elements more deeply, understand the formation of paleogeographical soil environment, soil Fertility development direction, the establishment of environmental background has a very important significance. This paper mainly expounds the characteristics and types of soil geochemistry in the Ulan Buh Desert and provides a scientific basis for the development of zoning utilization planning.
