'Biochar' represents an emerging technology that is increasingly being recognized for its potential role in carbon sequestration, reducing greenhouse gas emissions, waste management, renewable energy, soil improvement, crop productivity enhancement and environmental remediation. Published reviews have so far focused mainly on the above listed agronomic and environmental benefits of applying biochar, yet paid little or no attention to its harmful effects on the ecological system. This review highlights a balanced overview of the advantages and disadvantages of the pyrolysis process of biochar production, end-product quality and the benefits versus drawbacks of biochar on: (a) soil geochemistry and albedo, (b) microflora and fauna, (c) agrochemicals, (d) greenhouse gas efflux, (e) nutrients, (f) crop yield, and (g) contaminants (organic and inorganic). Future research should focus more on the unintended long-term consequences of biochar on biological organisms and their processes in the soil.
“生物炭”代表了一种新兴技术，其在碳固存、减少温室气体排放、废物管理、可再生能源、土壤改良、提高作物生产力和环境修复等方面的潜在作用正日益受到认可。迄今为止，已发表的评论主要集中在生物炭应用的上述农业和环境效益上，而很少或根本没有关注其对生态系统的有害影响。本综述强调了生物炭生产热解过程、最终产品质量以及生物炭在以下方面的优缺点的平衡概述：（a）土壤地球化学和反照率；（b）微生物区系和动物区系；（c）农用化学品；（d）温室气体排放；（e）养分；（f）作物产量；和（g）污染物（有机和无机）。未来的研究应更加关注生物炭对土壤中生物有机体及其过程的意外长期后果。
