摘　　要：生物炭是由生物质材料(如木材、禽畜粪便、作物残留物等)热解生成的富碳产物,其具有多孔结构、高比表面积、高吸附能力等特性,其特性赋予了生物炭在土壤改良、污染物治理、促进微生物群落结构变化及提升农业生产的环境效益等方面的巨大潜力。此外,生物炭可有效应对作物生产中遇到的挑战,如铝毒性较高、土壤pH值偏低等问题。文章综述生物炭对农田土壤微环境的影响和生物炭在土壤环境污染治理中的作用及其效应,以期为生物炭在土壤改良中的应用提供参考。Biochar,a carbon-rich product obtained from the pyrolysis of biomass materials such as wood,animal manure,and crop residues,exhibits distinctive properties including a porous structure,large specific surface area,and high adsorption capac⁃ity.These characteristics enable biochar to play a significant role in soil amelioration,pollutant mitigation,regulation of microbial communities,and enhancement of agricultural productivity.Furthermore,biochar shows a promising potential in addressing critical issues regarding agricultural soils,such as aluminum toxicity and low pH levels.This paper provides a comprehensive review of the effects of biochar on the microenvironment of farmland soils,with a particular focus on its efficacy in soil pollution remedia⁃tion.The findings aim to offer valuable insights for advancing the application of biochar in sustainable soil management practices.
