摘要
随着工业化进程的加快,人类活动对自然环境的影响越来越大,大气中PM2.5对人类健康的威胁逐步加剧,如何减轻PM2.5对人类的危害已经成为一个迫切需要解决的问题。通过分析国内外学者对PM2.5的研究成果,总结PM2.5的时空分布特征、组成特性、来源分类,以及世界主要国家、地区对PM2.5的监测标准,并基于森林植被对PM2.5的调控作用,指出通过合理建设森林植被达到有效调控PM2.5、降低PM2.5对人类的危害的目的。
The harm of PM2.5 on human is increasing with the quick development of industry and human activities.How to reduce the harm of PM2.5 is an urgent problem.By summarizing domestic and foreign researches on PM2.5,the paper analyzed its characteristics of temporal and spatial distribution,composition and sources.Also it introduced the monitoring standards of main countries or areas in the world.Finally,the relationship of PM2.5 and vegetation was emphasized.Suitable structure vegetation could help human to prevent PM2.5 effectively,so as to reduce its harm.
