道路林带对重金属的监测及防护作用研究现状

随着交通运输业的快速发展，车辆尾气、汽车磨损等造成了道路环境的重金属污染。道路林具有生物量大、生命周期长等优点，在重金属监测及污染防护方面的应用越来越广泛。文中在综述国内外相关文献的基础上，从道路林对重金属污染的监测，道路林对重金属的吸收、防护作用以及影响因素等方面阐述了道路林带在防护重金属污染方面的研究现状。

A Review of Roles of Road Tree Belts in Heavy Metal Monitoring and Pollution Prevention

With the rapid development of traffic transportation, vehicle exhaust, tires wear and brake has brought with heavy metal pollution. With the advantages such as large biomass, long life span, etc, road trees have been increasingly widely used in heavy metal monitoring and pollution prevention. Based on the domestic and foreign literatures, the paper reviewed the research status on the role of road tree belts in preventing heavy metal pollution in terms of heavy metal absorption, preventive effects and influence factors.
