长安街路面尘土残存量监测与尘土特性研究

Dust Remaining Mount Monitoring and Dust Characteristics Study of Chang'an Street

介绍了长安街道路清扫保洁作业质量即道路路面尘土残存量的监测结果,长安街道路清扫保洁作业质量处于北京市最优水平,年均值均低于10 g/m^2;根据数据统计分析长安街路面尘土残存量2015-2017年呈现逐年下降的趋势,年均值分别为9.1、8.2、6.8 g/m^2;对监测采样取得的长安街路面尘土开展了尘土的微观特性分析和尘土的粒径特性研究。

The monitoring results of the residual dust on the road in Chang＇an street was introduced. The quality of sweeping and cleaning of the road in Chang＇an street was at the optimal level in Beijing,with annual means less than 10 g/m^2. Statistically,the residual dust on the road in Chang＇an street had been declined from 2015 to 2017 ,with annual average of 9.1 g/m^2, 8.2 g/m^2 and 6.8 g/m^2 respectively. Finally, microscopic analysis and particle size characteristic study of dust sampled on the road in Chang＇ an street was carried out.
