【摘要】 植物作为城市生态系统的重要组分,有着重要的生态功能。但由于不当的城市绿地建设使得花粉致敏植物在城市中广泛引种栽培,加之气候变化和大气污染等多方面的因素,使得城市中花粉症患者数量激增。文章综述了花粉致敏植物的种类、物候特征和影响因素(不当的绿地建设、城市热岛效应和交通污染);以北京市为例,研究了北京城区花粉致敏植物的种类、分布和物候特征;提出了控制花粉致敏植物的建议,旨在为改善城市空气质量,建设合理城市绿地提供科学依据。更多还原

【Abstract】 Due to unsuitable green space construction,there are abundant allergenic pollen plants in urban area,producing allergenic pollens.It is a common and serious disease that a mass of airborne allergenic pollens could cause pollinosis badly influencing people’s robustness.The author reviews the research advances of allergenic plants,aiming to provide scientific base for reasonable green space construction.Firstly,species composition,phonological characteristics and influential factors,which include unsuitable green land construction,urban heat island effect,traffic pollution,etc,are summarized.Secondly,author takes Beijing as an example and studies species composition,distribution pattern and phonological characteristics in Beijing urban area.Thirdly,since the prevalence of pollinosis is rapidly increased in urban area,strategies,in order to allergenic pollen plants,are given out.Finally,there are still many problems worthy of more research,although great progress has been gained on the studies of allergenic pollen plants.For example,the mechanism of increased pollinosis influenced by allergenic pollen plants is needed to be further investigated,as well as the methodology.更多还原
