Abstract: Biochar is a carbon-rich solid substance through high-temperature pyrolysis under anaerobic conditions,which has the characteristics of high carbon content,rich pore structure,large specific surface area and stable physical and chemical properties. It is a kind of high quality soil improvement material. In this paper,the research progress of Biochar in influencing the physicochemical properties,soil nutrients and soil microorganisms of farmland soil in recent years were summarized,and the few application research of biochar in grassland system was also overviewed. Finally,the research focus and development of biochar in the grassland ecosystem were prospected in order to provide the theoretical basis and practical reference for the scientific application of biochar in grassland restoration.

Key words: Biochar, Soil properties, Grassland restoration

摘要: 生物炭是生物质材料在无氧条件下经高温热解而成的富碳固态物质,具有含碳率高、孔隙结构丰富、比表面积大、理化性质稳定等特点,是一种优质的土壤改良材料。本文总结归纳了近年来生物炭在影响农田土壤理化性质、土壤养分和土壤微生物方面的研究进展,同时也对生物碳在草地系统中的零星应用研究进行了概述,最后对生物碳在草地生态系统中有待深入的研究重点和发展进行了展望,以期为生物炭在草地修复中科学应用提供可借鉴的理论依据与实践参考。
