摘　　要：生物质炭对全球碳的生物地球化学循环和缓解全球气候变化具有重要的影响,已被认为是大气CO2的重要储库。现有研究表明,施用生物质炭在进行碳固持的同时,还可以通过改善土壤理化性质、提高土壤肥力、修复土壤污染等形式对区域及全球土壤生态系统功能产生影响。本文在文献资料调研的基础上,系统论述了生物质炭的主要性质以及生物质炭用于改良土壤的研究现状,评价了生物质炭化还田技术所具有的突出优势,并提出了今后研究中需要解决的关键问题。Biochar has great influence on global carbon biogeochemical cycle as well as climate change.It is believed that biochar should be an important pool of atmospheric CO2.Researches have showed that the application of biochar is of great importance in increasing soil carbon storage and have influences on soil ecosystem by improving soil physicochemical properties,improving soil fertility and immobilizing or absorbing soil pollutant.In this paper,the main characteristics of biochar were stated,the current research results on applying biochar to soil was discussed,the advantages of biomass-derived black carbon return to croplands were evaluated,and the key problems in further research were put forward.

关 键 词：生物质炭 土壤改良 土壤生态 固碳减排
