摘 要：
The sources,harms,management methods to the traffic noise and advantages of eliminating the noise by green belts were introduced.Research status of traffic noise attenuation by green belts was reviewed from the views of the plant characteristics and the structure of green belts.Three suggestions were put forward:1) green belts with the width of 30-70 m,which consisted of interlaced planted arbors and shrubs with wider and hairy leaves,more branches,low branching-point near the road could reduce traffic noise more efficiently;2) more attenuation should be paid to the researches of mechanism and factors related to traffic noise by green belts;3) predictive models for traffic noise attenuation by green belts which included plant characteristics and green belt structures should be established.
