气象因子对城市植物叶面颗粒物的影响研究

Research on the Effect of Meteorological Factors on Urban Plant Foliar Particulate Matter

城市植物可以有效阻滞颗粒物,改善空气质量。目前,国内外已经积累大量有关不同植物类型累积颗粒物差异性的研究,但是植物叶面滞留颗粒物的含量受到多种气象因子的影响。该研究分别从降雨、风速、行星边界层等角度,阐述了不同气象因子对植物叶面滞留颗粒物含量产生的影响。今后需要加强气候因子对叶面细颗粒物的去除机理研究,有利于了解颗粒物沉积于叶面的动态以及机制;在降雨因素方面应进行长期监测,充分掌握城市植物叶面颗粒物在降雨作用下的年变化量,有助于建立全面的城市植物滞留颗粒物含量数据库,为今后合理有效利用城市植物提供理论指导,同时为大气污染物与城市植物相互关系的深入研究提供新的思路。

Urban plant can block particles effectively and improve air quality. At present domestic and overseas has accumulated a large number of studies of different plant type differences between accumulated particulate matter,but plant foliar stop particles content under the influence of various meteorological factors. This paper respectively from the aspects such as rainfall,wind speed,planetary boundary layer,expounds the effects of meteorological factors on different plant foliar stop the effects of particulate matter content. Need to strengthen in the future climate factor on leaf fine particle removal mechanism research,is helpful to understand particles deposit on the leaf of the dynamic and mechanism; In rainfall factors should carry on the long-term monitoring,fully grasp the city plant leaf particles under the influence of rainfall amount of annual change,help build a comprehensive urban plant stranded particles content database,rational and effective use of urban plants provide theoretical guidance for the future,at the same time for the further study of the relationship between air pollution and urban plant to provide new ideas.
