摘　　要：以郑州市新107国道为例,对绿化林带两侧空气中颗粒物的浓度进行了观测.主要测定了TSP,PM10,PM2.5,PM14种粒径的颗粒物浓度.结果表现为:4种粒径的空气颗粒物浓度从8:00—18:00的日变化趋势呈倾斜的"L"形,呈上午高,下午低的走势;绿化林带能净化空气中的颗粒物,对TSP和PM10的净化效果比PM2.5,PM1的效果好;颗粒物浓度跟车流量呈正相关,跟风速呈负相关.This study takes the new National Trunk Highway No.107 in Zhengzhou city as the research object. Atmospheric particles concentration along green belts was tested. Particles concentration of four kinds of particle sizes of TSP, PM10, PM25, PMI was mainly analyzed. The results showed that the variation of particles concentration of four kinds of particle sizes from 8：00 to 18：00 show on ＂L＂. Particles concentration is high in the morning, low in the afternoon. Green belts can reduce atmospheric particles. The removal effect of TSP and PM10 is better than PM25 and PM1. There was positive relation between particles concentration and traffic flow. And there was negative relation between particles concentration and wind speed.
