摘要：【目的】研究华南地区城市公园中常见园林植物挥发性有机物质(BVOCs)组分差异及时间动态规律,为城市公园植物选择和搭配提供参考。【方法】以广州天河公园9种园林植物为研究对象,通过顶空固相微萃取–气相色谱–质谱联用法(HS-SPME-GC-MS)对样品在不同物候期下的BVOCs成分进行鉴定,并利用峰面积归一化法确定各组分的相对含量。【结果】不同植物释放的BVOCs组成及相对含量存在一定差异,植物花朵释放的BVOCs成分在不同物候期下较植物叶片差异明显。9种园林植物共检测到萜烯类、醇类、醛类、酯类等11类挥发物。不同植物释放的BVOCs组成类别及释放特性同样存在差异,但优势化合物类别基本稳定。其中白兰以醇类、酯类、萜烯类为主;四季桂、女贞、阴香花以醇类、醛类、酯类和萜烯类为主;杧果、羊蹄甲、樟、枫香、落羽杉以萜烯类为主;柠檬桉以醇类、酯类和萜烯类为主;阴香叶片以醇类、醛类、萜烯类为主。植物释放有益BVOCs相对含量与物候变化有一定关联。白兰、杧果、阴香的花在初花期释放的有益BVOCs相对含量最高(84.7%、97.6%、70.1%);四季桂、女贞、羊蹄甲、樟的花则在末花期释放的有益BVOCs相对含量最高(78.8%、79.1%、94.1%)。枫香和柠檬桉的叶片释放的有益BVOCs在秋冬季相对含量达到峰值(98.2%、67.0%),而落羽杉和阴香的叶片则在夏季达到峰值(99.7%、88.1%)。【结论】BVOCs成分和相对含量与植物种类和物候存在相关性,在营造城市公园时应考虑植物配置,以达到“四时花香”的嗅觉景观,助推实现人与自然和谐共生的健康与福祉等可持续发展目标。
[Objective] This paper investigates the component differences and temporal dynamics of volatile organic matter(BVOCs) released by common ornamental plants in urban parks of southern China,so as to provide references for plant selection and collocation in urban regions.[Method] Nine ornamental plant species from Tianhe urban park in Guangzhou City were identified by headspace solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS),and the relative contents of each component were determined by peak area normalization method.[Result] The composition and relative content of BVOCs released by different ornamental plants were different to some extent,and the composition of BVOCs released by plant flowers was significantly different from that of plant leaves at different phenological stages.A total of 11 volatiles(e.g.terpenes,alcohols,aldehydes and esters) were detected in nine ornamental plant species.The composition and release characteristics of BVOCs released by different plants varied,but the types of dominant compounds generally remained stable.The components of BVOCs in different plant species were different and the release characteristics were different under varied phenological periods,but the dominant compounds were relatively stable.Michelia × alba was mainly composed of alcohols,esters and terpenes.Osmanthus fragrans,Ligustrum lucidum and Cinnamomum burmanni flowers were mainly composed of alcohols,aldehydes,esters and terpenes.Mangifera indica,Bauhinia purpurea,Cinnamomum camphora,Liquidambar formosana and Taxodium distichum were mainly composed of terpenes.Eucalyptus citriodora leaves were mainly composed of alcohols,esters and terpenes.Leaves of Cinnamomum burmanni were mainly composed of alcohols,aldehydes and terpenes.The relative content of beneficial BVOCs released by plants was related to phenological changes.The contents of beneficial BVOCs in Michelia × alba,Mangifera indica and Cinnamomum burmanni were the highest(84.7%,97.6%,70.1%) in the early opening stage.In addition,the contents of beneficial BVOCs were the highest(78.8%,79.1%,94.1%) in the last opening stage.The relative content of beneficial BVOCs released by the leaves of Liquidambar formosana and Eucalyptus citriodora reached the peak value(98.2%,67.0%)in autumn and winter,while the content of beneficial BVOCs released by Liquidambar formosana and Cinnamomum burmanni reached the peak value(99.7%,88.1%) in summer.[Conclusion] The composition and relative content of BVOCs are correlated with plant species and phenology.Plant configuration should be considered in the construction of urban parks to achieve the smellscape of diverse seasons,and help realize the sustainable development goal of good health and well-being of harmonious coexistence between human beings and the nature.
