绿化植物防治空气颗粒物污染研究进展

空气颗粒物污染日益加剧导致空气质量不断恶化, 严重威胁到人类健康和生存环境, 已引起世界各国的高度重视。为了减轻空气颗粒物污染危害, 利用绿化植物防治空气颗粒物污染作为一种有前景的、安全可靠的绿色治理技术应运而生。立足于国内外在绿化植物防治空气颗粒物污染方面的研究成果, 文中系统总结了绿化植物防治空气颗粒物污染的5个作用途径, 即减尘作用、滞尘作用、吸尘作用、降尘作用和阻尘作用, 并指出利用植物防治空气颗粒物污染存在的问题与研究需求, 建议今后应进一步加强植被防治空气颗粒物污染的形成机制、植物防治技术体系与治理模式等研究。

Overview of Studies on Greening Plants Effects on Particulate Air Pollution Control

The fast increasing particulate air pollution is leading to increasing deterioration of air quality throughout the world, which seriously threatens the human health and the living environment and has aroused high attention around the world. In order to reduce the hazards of the particulate air pollution, the phytoremediation technology of particulate air pollution has emerged as a promising, safe and reliable green treatment. Based on the current achievements of global studies on the particulate air pollution control using greening plants, the paper summarized five possible controlling approaches to the particulate air pollution with greening plants, i.e., preventing, detaining, absorbing, depositing and blocking dusts. In addition, the paper pointed out the existing limitations and future research needs on the phytoremediation of particulate air pollution. It was suggested that more studies would be adopted for know the the formation mechanism, technical system and management model concerning the phytoremediation technology of particulate air pollution in the future.
