中文摘要 随着城市化和工业化进程不断加快,春夏季臭氧(O₃)污染和秋冬季颗粒物(PMs)污染等复合大气污染问题成为困扰我国各大城市的环境难题,严重威胁城市森林的碳汇潜力和净化空气等生态系统服务功能。筛选既具有较强吸收O₃和PMs能力且具有较低植源性挥发性有机化合物(BVOCs)释放量的抗性树种,是当今维持城市森林生态功能和人类福祉的重要保障。文章通过整合已发表的文献数据,运用权重赋值法和综合因子分析,解析我国常见386种绿化树种的O₃吸收能力、PMs吸附能力、BVOCs释放速率以及复合效应。结果表明:侧柏、圆柏和毛白杨表现出较强的O₃和PMs吸收、吸附能力和较低的BVOCs释放量,可作为综合抗性能力较强的城市绿化树种进行推广;悬铃木、鹅掌楸和枫香表现出较弱的O₃抗性和PMs吸附能力且BVOCs释放速率较高,不适宜作为城市绿化树种栽植。因此,在适地适树的基础上,城市绿化需要综合考虑树种景观布局和下垫面大气污染的组分和严重程度,选择适宜的绿化树种进行绿化布局,最大限度地发挥绿化树种在城市建设中的生态效益。

英文摘要 With the accelerating process of industrialization and urbanization, the combined air pollution, such as volatile organic compounds (VOCs), ozone (O3) and particulate matter (PMs), has become the main environmental problem haunting major cities in China, which seriously threatens the services and functions of urban forest ecosystem including carbon sink and air purification. Screening the species with a strong absorption of O₃ and PMs and a low release of BVOCs will be the guarantee for maintaining urban forest ecosystem function and human well-being. Based on the published literature, this paper comprehensively analyzes the absorption capacity of O₃ and PMs, the release rate of BVOCs and combined effects of 386 common greening tree species using weight assignment and comprehensive factor analysis. The results show that the tree species of Platycladus orientalis, Sabina chinensis and Populus tomentosa have a strong absorption capacity of O₃ and PMs and low release rate of BVOCs, which could be promoted in urban greening with strongest tolerance; Juglans regia, Ginkgo biloba and Paulownia fortunei are the tree species with medium absorption capacity of O₃ and PMs and high release rate of BVOCs, which are not suitable for use in urban greening. In consideration of the principle of suitable trees for suitable places, more attention would be paid to the landscape layout with urban tree species and the composition and severity of air pollution at the underlying surface in urban greening. Thus, suitable greening species should be selected to maximize the ecological benefits of these species in urban construction.
