【摘要】近几年来,随着巴西亚马逊流域考古发现黑土(black earths,或terra preta de indio(葡萄牙语))及研究的深入,认为将生物质炭化还田不仅能藏碳于土,减缓全球气候变化,而且能提高全球粮食安全保障.生物质在无氧或低氧条件下高温裂解炭化而成的产物被称为生物炭(biochar).本文将从生物炭特性;生物炭对作物产量和养分吸收的影响;生物炭分解和对土壤碳周转的影响以及对污染物降解和生物有效性影响方面进行综述,以期为国内生物炭研究提供参考.%In recent years, with deeper investigation on black earths found by archeologists in Amazon region, Brazil, it is considered that amendment of biochar pyrolyzed from biomass under little oxygen can not only alleviate global warming speed as a result of storing carbon in soil, but also may improve soil quality which would secure food safety. In this paper, biochars' properties, influences on crop yield and nutrients uptake, decomposition and effects on soil carbon turnover, and degradation and bioavailability of organic pollutants were compiled. Furthermore the key perspectives were highlighted for future research.【总页数】5页(857-861)
