土壤中铁锰结核的研究进展

通过对国内外近几十年关于土壤铁锰结核研究的文献进行系统梳理,总结了土壤中铁锰结核的成因、物质组成、形态构造及其与环境变化的关系等方面研究成果。发育于土壤中的铁锰结核形成过程受到环境条件的严格限制,因此各种理化性质都是环境的产物,是反映环境变化信息的良好载体。然而,目前对土壤铁锰结核的研究尚存在如空间分异的规律及机理不清、年代学薄弱等不足。

Research Advance of Ferromanganese Nodules in Soil

Through the combing of domestic and international literatures on soil ferromanganese nodules research,the causes of soil ferromanganese nodules,material composition,morphological structure and its relationship with environmental changes were summarized.Development of ferromanganese nodules in the soil formation was strictly limited by the environmental conditions.The nodules＇ variations of physical and chemical properties are the products of the environment.The ferromanganese nodules were believed to good information carrier for the study of climate change.Currently there were still weaknesses of the ferromanganese nodules research in soil,such as the mechanism of spatial variation,chronology and so on.
