对深圳地区的主要园林树种、地带性植被的代表种共计158种植物释放的生物源的挥发性有机物(biogenic volatileorganic compounds,BVOCs)采用流动式、封闭式采样法采样,运至美国进行GC-MS分析测量.结果表明,短穗鱼尾葵(Caryotamitis)、海红豆(Adenanthera pavonina var.microsperma)、杧果(Mangifera indica)、海漆(Excoecoria agalloch)等31种植物具有释放异戊二烯的能力;另有鸡蛋果(Passiflora edulis)、小琴丝竹(Bambusa glaucescens cv.silverstripe)、山苍子(Litsea cubeba)、大型双子铁(Dioon spinulosum)等52种植物具有释放单萜烯类化合物的能力.对红树植物的测量表明,该类植物普遍具有释放单萜烯的能力.上述结果为建立深圳及周边地区的环境质量模型提供了重要数据,同时也可为我国热带亚热带城市大面积绿化以及经济林、生态林和防护林等的树种选择提供参考.
A total of 158 plant-derived biogenic volatile organic compounds (BVOCs), representative of major plantation species and zonal vegetation in Shenzhen, were collected by flow-type and closed-sampling methods and transported to the United States for GC-MS The results showed that 31 species of plants, Caryotamitis, Adenanthera pavonina var. Microsrosperma, Mangifera indica and Excoecoria agalloch were able to release isoprene 52 species such as Passiflora edulis, Bambusa glaucescens cv.silverstripe, Litsea cubeba and Dioon spinulosum were also found to release monoterpenes. The measurement of mangrove plants shows that these plants generally have the ability to release monoterpenes.The above results provide important data for establishing the environmental quality model in Shenzhen and the surrounding areas, and can also provide important data for large-area afforestation and economic forest in the tropical and subtropical cities in China, , Ecological forest and shelterbelts and other tree species to provide a reference.
