Biogenic volatile organic compounds (BVOCs) emitted by plants contribute to secondary air pollution through photochemical reactions in sunlight. Due to the influence of multiple factors, accurately characterizing and quantifying the emission of BVOCs from plant sources is challenging, which poses significant obstacles to the effective management and control of BVOCs. Therefore, this paper summarizes the emission mechanisms of BVOCs from plants, explores the primary factors influencing variations in the emission rates of these compounds, and evaluates the advantages and limitations of contemporary "measurement-modeling" methods for characterizing BVOC emissions. It is concluded that current measurement techniques still need to be further developed to meet the criteria of simplicity, affordability, and high precision simultaneously, and in terms of modeling and prediction studies, there is a lack of in-depth research on the atmospheric chemistry of BVOCs and the synergistic effects of multiple factors. Finally, it is suggested to leverage interdisciplinary strengths to develop advanced measurement technologies and high-resolution models for monitoring volatile compounds. Additionally, strategically selecting low-BVOC tree species in pollution-vulnerable urban areas-contingent on rigorous ecological assessments-combined with stringent controls on anthropogenic precursors (e.g., anthropogenic volatile organic compounds (AVOCs)) could serve as a complementary measure to mitigate secondary pollution.
植物排放的生物源挥发性有机化合物（BVOCs）通过阳光中的光化学反应导致二次空气污染。由于多种因素的影响，准确表征和量化植物源BVOCs的排放具有挑战性，这给BVOCs的有效管理和控制带来了重大障碍。因此，本文总结了植物BVOCs的排放机制，探讨了影响这些化合物排放速率变化的主要因素，并评估了当代用于表征BVOC排放的“测量-建模”方法的优缺点。得出的结论是，当前的测量技术仍需进一步发展，以同时满足简单性、可承受性和高精度的标准，并且在建模和预测研究方面，对BVOCs的大气化学和多因素协同效应缺乏深入研究。最后，建议利用跨学科优势开发先进的测量技术和高分辨率模型来监测挥发性化合物。此外，在经过严格生态评估的污染易受害城市地区，有策略地选择低BVOCs的树种，并结合对人为前体（如人为挥发性有机化合物（AVOCs））的严格控制，可以作为减轻二次污染的补充措施。
