摘　　要：根据近年来我国大气污染情况较为严重,以及冬季北方长时间没有绿色植物的的现状,本文介绍了一种可以放置在城市道路绿化带上的木质过滤板,以实现在冬季代替绿色植物对大气污染物进行吸附,降低空气污染的目的。参照国家标准,通过对木质过滤板进行实地道路试验,结果显示,经过过滤板的PM2.5平均值比之前的数值低15%左右,说明木质过滤板对PM2.5具有一定的吸附能力。试验板能谱分析中检测出C、N、Pb、F等元素,说明木质过滤板不仅可以过滤道路交通导致的污染物,还能够吸附大气中的其他污染物,起到一定的隔绝污染物、净化空气的作用。According to the serious situation of air pollution in our country in recent years and the absence of green plants in win-ter in the northern part of China, this paper introduced a wooden filter plate that can be placed on urban road green belt, in order to achieve the air pollutants adsorption in winter instead of green plants, to reduce air pollution. Referring to the national standards, the wooden filter plate was tested on the road. The results showed that the average PM2. 5 of the filter plate was about 15% lower than that of the previous value, indicating that the wood filter board had a certain adsorption capacity for PM2. 5. The G, N, Pb and F ele-ments could be detected in the spectrum analysis. It showed that the wooden filter plate can not only filter pollutants caused by road traffic, but also adsorb other pollutants in the atmosphere, and play a role of isolating pollutants and purifying air.
