土壤黑碳的研究进展

Advances on Research of Black Carbon in Soil

本文对土壤黑碳(B lack Carbon)的形成与降解?测定方法?影响因素及其在土壤中的作用等方面的研究进展进行评述,并提出未来应重点加强的几个研究方向:1)黑碳测定的标准物质和标准方法的研究;2)火烧历史和频率对黑碳的影响研究;3)黑碳降解机理方面的研究.

The Black Carbon＇s formation and decomposition, analytical approaches, affecting factors （burning, land use and fertilizations） and their functions in soils are reviewed and summarized. We conclude that the following researches should be strengthened ： the realization of uniform determination of Black Carbon, together with the improvement of measuring precision and range ; reasonable evaluation of Black Carbon＇s reactions to different kinds of burning; deep understanding of the decomposition mechanism of Black Carbon.
