【摘要】 生物炭在农业土壤改良、环境修复和绿色可持续发展等方面应用广泛。生物炭通过多种作用过程来改善土壤环境以保证土壤生态系统稳定。系统地梳理了生物炭对土壤典型酶活、土壤微生物、土壤养分、土壤碳库和土壤生态修复的影响及研究进展，在此基础上提出了生物炭对土壤改良作用机制，为土壤固碳培肥和健康培育提供了理论参考。更多还原

【Abstract】 Biochar is widely used in agricultural soil improvement,environmental remediation,and green sustainable development.Biochar improves soil environment through various processes to ensure soil ecosystem stability.This research systematically reviewed the effects and research progress of biochar on typical soil enzyme activity,soil microorganisms,soil nutrients,soil carbon pool,and soil ecological remediation.Based on this,the mechanism of biochar’s effects on soil improvement was proposed,providing theoretical reference for soil carbon fixation,fertilization,and healthy cultivation.更多还原
