城市中的花粉致敏植物及其影响因素

Allergenic pollen plants and their influencing factors in urban area

大量致敏花粉飘散于空气中会引发花粉症,严重危害人体健康。由于不当的城市绿地建设使得花粉致敏植物在城市中大量聚集,加之城市热岛效应和交通污染等多方面的因素,使得城市中花粉症患者数量激增。综述了花粉致敏植物的种类、物候特征和影响因素提出了控制花粉致敏植物的建议;总结了目前花粉致敏植物研究中应进一步关注的问题,旨在为改善城市空气质量,建设合理绿化环境提供科学依据。

Due to unsuitable green space construction, abundant allergenic pollen plants are centralized in urban area, producing allergenic pollens. A mass of airborne allergenic pollens could cause pollinosis badly influencing people＇s robustness. To provide scientific base for reasonable virescence construction, the research advances of allergenic pollen plants were reviewed. Firstly, species composition, phonological characteristics and influencing factors, which include unsuitable green land construction, urban heat island effect, traffic pollution, etc, were summarized. Secondly, the strategies controlling allergenic pollen plants were given out. Thirdly, some problems on allergenic plants worthy of more research, including allergenic mechanism and methodology, were also put forward.
