In this work, the differences among the vertical distribution of pollutant PM2.5 concentration of three urban land types near the ground were analyzed to get the data on pollutant PM2.5 concentration of urban water, green space and road in Xi’an. The Guang Yuntan waters of Ba River, the green space of Binhe Park in western bank of Ba River, the roadside that is 400 m away from western bank of Ba River was selected as the monitoring points among which four monitoring periods were set and pollutant PM2.5 concentration data were collected with UAV (unmanned aerial vehicle) monitoring platform between 0m to 100 m. The experimental results show that pollutant PM2.5 concentration data is different in the vertical distribution of PM2.5 near the ground. The changes of the vertical distribution of PM2.5 concentration existing in such three types of land as waters area, green space and roads are also different at the same time, especially at 8:00 am. The same monitoring point during different periods differs in a tendency of high value in the morning and low in the afternoon to analyze from the perspective of different monitoring points at the same time, there exists difference between the vertical distribution of pollutant PM2.5 near the ground impacted by different urban land types. |
