城市植物源挥发性有机化合物排放特征及其大气环境效应研究进展

在外界环境的刺激下，植物会通过释放挥发性有机化合物来维护自身生长。城市是人类活动的主要集聚地，剧烈的人为干扰导致城市环境特征呈现出复杂的变化趋势，从而使城市植物排放挥发性有机化合物的过程与自然界出现较大差异。城市中的植物源挥发性有机化合物(Biogenic Volatile Organic Compounds, BVOCs)会直接与城市中的氧化物质接触，生成二次污染物，并在高温、强光照的条件下发生光化学反应，严重破坏城市大气环境，危害居民健康。总结了城市BVOCs的常见类型、作用机制及现有研究方法，分析了不同时间、空间和人类活动背景下的城市BVOCs排放特征，并进一步梳理了当前研究的不足，提出未来重点研究方向，旨在为大气环境治理、环境空间规划、居民健康保障等方面的城市管理工作提供指导。

Research progress on the emission characteristics of volatile organic compounds from urban plants and their atmospheric effects

Under the stimulation of the external environment, plants will maintain their own growth by releasing volatile organic compounds. Urban areas are the main places of human activities. Intensely anthropogenic disturbances lead to complex changes in urban environmental characteristics, which makes the emission of volatile organic compounds from urban plants greatly different from that of natural plants. The biogenic volatile organic compounds (BVOCs) in urban area can directly contact with the oxidizing substances, generating secondary pollutants, and cause photochemical reactions under high temperature and strong light conditions. BVOCs could seriously deteriorate the urban atmospheric environment and harm the health of residents. This paper summarized the common types, action mechanisms, and existing research methods of urban BVOCs, analyzed the emission characteristics of urban BVOCs in different temporal, spatial, and human activity contexts. We further combed the limitations of current researches, and proposed the future research directions. The objective of this paper is to provide guidance for urban management in atmospheric environment management, environmental spatial planning, and residents'' health protection.
