The Strategy for Air Pollution Decision Services of Six Urban Districts in Tianjin
Journal Title: International Journal of Mathematics and Statistics Invention - Year 2017, Vol 5, Issue 7
Abstract
Tianjin has been undergoing long-time air pollution in recent years. According to the real-time observational data, which is collected through eight monitoring stations of Tianjin Environment Monitoring Center (the center monitoring station has been changed in the middle of the monitoring) in six urban districts in Tianjin, the paper provides statistical analysis of data sequence about Air Quality Index (AQI), PM2.5, PM10, SO2, NO2, O3 and CO, and summarizes air pollution decision services in Tianjin. The analysis indicates that the air pollution in Tianjin is mainly caused by PM2.5 and PM10, and centrally occurred in winter. Two pollution peaks are December and January 18th to February 14th period. December is the main period of time when exists hazardous air pollution, which is featured by long duration and high pollution intensity. Currently, Tianjin is focus on coal-controlling and emission reduction, and Co-prevention and Co-management in BeijingTianjin-Hebei Region to control the air pollution.
