摘要

生物源挥发性有机化合物(BVOCs)是陆地生态系统与大气环境物质交换和信息传递的重要组分,在生物地球化学循环、气候变化及生态系统功能中扮演着重要角色.土壤生态系统既是大气BVOCs的重要来源,也是其不可忽视的潜在的汇.系统梳理了土壤BVOCs的研究进展,重点阐述了土壤中BVOCs的主要来源(土壤有机质、凋落物分解、植物根系和微生物代谢)和土壤汇途径(大气干湿沉降、物理吸附溶解和微生物降解).总结了土壤BVOCs通量的季节性变化和不同生态系统间的差异,并探讨了在全球气候变化背景下(增温、干旱、氮沉降),土壤BVOCs源汇平衡的潜在响应机制.最后,梳理了当前研究的不足,并提出了未来重点研究方向,旨在为全面理解BVOCs在土壤生物地球化学循环过程中的作用提供新视角.

Abstract

Biogenic volatile organic compounds (BVOCs) are critical components linking terrestrial ecosystems with the atmospheric environment for gas exchange and information transfer, and they have played essential roles in biogeochemical cycles, climate change, and ecosystem functioning. Soil ecosystems serve as both significant sources and indispensable potential sinks for atmospheric BVOCs. In this review, the progress in soil BVOCs research was systematically synthesized. Their main sources in soil (soil organic matter, litter decomposition, plant roots, and microbial metabolism) and soil sink pathways (atmospheric dry and wet deposition, physical adsorption and dissolution, and microbial degradation) were highlighted. Furthermore, the seasonal variations and ecosystem-specific differences in soil BVOCs flux were summarized, and the potential mechanisms of soil BVOCs source-sink dynamics in the context of global climate change (warming, drought, and nitrogen deposition) were explored. Finally, current research gaps were elucidated, and future key research directions were proposed, aiming to provide new insights for a comprehensive understanding of the role of BVOCs in soil biogeochemical cycling processes.
