    摘要
  • 摘要: 利用移动监测方法采集2016年7月14—16日上海市不同功能街区及道路环境的PM2.5、PM10、水膜高度等数据,研究城市不同街区及道路环境PM2.5和PM10浓度分布规律及影响因素。结果表明:降水对PM2.5具有明显的去除效果,水膜高度与颗粒物浓度的变化存在负相关关系。生活区和虹桥商务区内的颗粒污染物以细颗粒为主,虹桥商务区和工业区的部分微环境分别由于工地和路面扬尘的影响会出现PM2.5~10浓度严重升高的现象。小陆家嘴商务区的污染物扩散较好,不易堆积,该街区内没有污染十分严重的区域。实测证明,并不是所有的高架桥都会加重街道峡谷内的空气污染,合理的街道峡谷构造条件下,高架桥对街道峡谷内污染物扩散影响不大。

     

    Abstract: In order to understand the distribution and influencing factors of PM2.5 and PM10 concentration in different neighbourhoods and road environments, the data of PM2.5 and PM10 concentration and water film height collected from different functional blocks during July 14 th to July 16 th, 2016 were analyzed. The result showed that the rainfall helped decrease the concentration of PM2.5 in the ambient environment, and there was a negative correlation between the water film height and particulate matter concentration. Fine particle pollutants predominated in the particulates of residential areas and Hongqiao business district. In addition, due to the impact of the construction sites and road dust, there were serious coarse particle pollutants somewhere in Hongqiao business district and industrial areas. The pollution in Lujiazui business district was slight because the diffusion condition was fine and there were no serious polluting blocks. According to the measurement results, not all the viaducts will deteriorate the air quality in the street canyons, and the viaducts will have little effect on the diffusion of pollutants in the street canyon if the structure of the street canyon is reasonable.
