北京计划在今年用具有强滞尘能力的植物升级城市绿化带以对抗PM2.5提升空气质量。18种植物已被挑选用于此试验项目。
 
After two years of spot monitoring on different areas of the city and statistical2 analyses, the Beijing Institute of Landscape Architecture found that proper plantation3 for green belts could reduce the PM2.5 density4 by 10 to 20 percent. Based on the research findings, Beijing decided5 to plant more woody plants, shrubs6 and swards that have a strong capability7 to detain dust. 
 
The 18 types of plants, selected out of more than 60, include acer truncatum, persimmon tree, Chinese scholar tree, ginkgo, heaven tree, catalpa bungei, juniper, gutta percha tree, Chinese white poplar, Koelreuteria, Robinia pseudoacacia, Prunus-cistena, clove8 tree ,Lespedeza, hibiscus, flowering plum, peony and Malus "Sparkler." 
 
The Beijing Institute of Landscape Architecture will first work with landscape design companies to set up experimental areas in Tongzhou, east suburb of Beijing, and later to promote these plants to a wider range of areas in the city.
