大气污染的植物修复研究进展

大气污染是人类面临的严重环境问题之一,植物除了可以监测大气的污染外,在近地表大气污染物的清除中起着重要作用。利用植物净化大气污染物是1种低碳、有效、非破坏型的环境污染修复方式,植物净化污染大气的思想及其技术对城市园林绿化、环境规划和生态环境建设等具有直接的指导意义和应用价值。笔者介绍了大气污染的种类、植物净化大气污染的机理、植物净化大气污染的主要过程,提出了筛选高效净化植物、开发联合修复技术、培育转基因净化植物及合理植物配置等是未来研究的主要方向。

Research on the Phytoremediation of Atmosphere Pollution

The atmosphere pollution is one of the serious environment problems.Plant plays an important role in the cleanup of pollutants in atmosphere near the earth＇s surface.Phytode contamination is a cost-effective,noninvasive alternative and complementary technology for engineering-based remediation methods.The idea and technology of phytodecontamination of atmosphericollution have direct guideline and application values for city landscaping,environment planning and ecological construction.The variety of atmosphere pollution was discussed by authors.The mechanisms of phytodecontamination of atmospheric pollution.The main process of phytodecontamination atmosphere hemical pollution.The main developing directions are to screen-out high efficient decontamination plants,investigate the decontamination mechanism of pollutants in the plants and the factors influencing decontamination effects,develop combined remediation technology,cultivate transgenic decontamination plants and plants disposition.
