路侧植被对道路交通颗粒物垂直分布的影响研究
Investigating the Influence of Roadside Vegetation on the Vertical Distribution of Road Traffic Particulate Matter
摘要
Abstract
Taking the northern segment of the West Third Ring Expressway in Fuzhou City as an experimental section,this research used unmanned aerial vehicle platform equipped with miniature environmental sensors to collect high spatiotemporal resolution concentration samples of PM1.0,PM2.5,and black carbon(BC)within a height range of 100 meters after the roadside green belts.The vertical distribution characteristics of these particles under different vegetation densities were statistically analyzed.The results indicate that:(1)when the traffic source is not raised,the concentration of particulate matter on the roadside of the road without vegetation fluctuates distributes in a fluctuating pattern with the increase of altitude and the change range is not large,(2)When the traffic source is elevated by an elevated road,dense vegetation next to the viaduct can effectively reduce the concentrations of PM1.0 and PM2.5 below the bridge deck,but significantly increase BC concentration.(3)High-density vegetation can inhibit the rise of particulate matter,thereby exacerbating low-altitude traffic pollution.关键词
