Study On The Environmental Planning And Management By Airquis

In this paper, which is air part of the SINO-Norwegian co-operation project Environmental Surveillance and Information System. According to the data imported to the model late in 2007 and different model scenarioes, using the dispersion model(EPISODE) the spatial distribution of different pollutants is calculated and shown on the GIS map. Through the map which different colour means different pollution, we can tell which scenario is better for environment. So the abatement was made and the reference scheme is provided for the environmental planning and management.To play a very important role in practical work, the model and GIS part of the system is the key, so this paper make a detail introduction about them, and also, sourecs investigation, model result on the GIS map, daily report&forcast by AirQUIS is introduced.In this paper ,useing air pollution dispersion model called EPISODE, the annual concentration of SO2 is simulated near the west suburb and bearing plant monitoring site. From the resoult we can see that the main reason caused bearing plant site high SO2 concentration is the emission from the low-source and area source, and the reason for west suburb including low-source, area source and the elevated Source. So if we want to decrease the SO2 concentration of west suburb, the low-source and area source must be controlled strictely, and the elevated source also must be controlled though its affection to the air is slight.The results of Nox and PM10 are simulated through the EPISODE model, and shown on the GIS map, through analyzing the results the abatement and the application of NOX and PM10 is discussed.
