Abstract: | There are serious pollution of enterprises in the BTH and its surrounding area,especially in the rural-urban continuum areas.Non-point source pollution is difficult to control.Rapid and accurate determination of targets for air pollution monitoring and informationization of on-site environmental law enforcement are the keys to the monitoring of atmospheric environment.This paper retrieves haze,PM2.5,NO2 and SO2 from the MODIS and OMI data.based on the comprehensive analysis of the satellite data of twelve typical heavy pollution episodes since September 2016,we have calculated the Heavy Pollution High Incidence Index(HPHII),and then combined with the high resolution images to find out the suspected gathering area of the polluting enterprise as the key areas of environmental supervision.This work will provide technical support for environmental law enforcement and improve the accuracy of law enforcement and law enforcement efficiency effectively,so as to solve the problem of human shortage in environmental monitoring. |
