生物炭对土壤团聚体及结合态碳库影响研究进展

摘要

生物炭是生物有机材料在缺氧环境中经热裂解后的芳香化难溶的固体产物，大多为粉状颗粒，属于黑炭的一种。生物炭不仅调节土壤活性，增强土壤吸附能力，还增加了土壤的贮碳功能。本文综述了生物炭的理化特性及其对土壤团聚体、结合态碳库影响的研究进展。%Biochar is an aromatized refractory solid product from bio-organic materials by thermal crack-ing in hypoxia environment.It is a kind of black char with and mostly powder particles.Biochar can not only act as active soil conditioners to enhance soil adsorption properties,but also promote the soil carbon storage function.The physical and chemical properties of biochar were summerized in this paper,and also the re-search progresses of its influences on soil aggregate and combined state of carbon sinks.
