生态城市要求运用生态学原理来指导道路绿地的布局设计。机动车尾气污染是当前城市空气污染的主要污染源。通过对不同车流量、不同水平距离、不同垂直距离、不同季节的情况下,空气中的铅、PM^10（空气动力学直径≤10微米的颗粒物）、PM^2.5（空气动力学直径≤2.5微米的颗粒物）和土壤中的铅四种污染物的浓度变化规律的研究,为道路绿地设计提供生态学参考,从而减轻尾气污染对城市环境和人体健康的危害。

Eco-city requests to design the road greenland by the ecological theory.The vehicle exhaust pollution is the main source of the current pollution to city air.This paper studies the changing rules of four contaminations concentration about Pb,PM^10 and PM^2.5 in the air and Pb in soil,in different traffic flow,different horizontal distance,different vertical distance and different season,so as to lay the ecological foundation for the design of road Greenland and reduce the harm of exhaust pollution to people＇s health.
