Abstract
This thesis has provided a detailed survey of the basic situation of air pollution sources (point sources, non-point sources and line sources) in Chengdu urban agglomeration and calculated the pollutant emissions for each type of pollution sources by using the pollution source monitoring data (on-line monitoring and routine monitoring) or emission factor method. A temporal allocation has been carried out for the emissions of each type of sources (point sources, non-point sources and line sources) according to the production characteristics of the industrial enterprises which discharge air pollutants, the working and living law of human being and driving rules of vehicles. As for the spatial allocation of pollution sources, enterprises with confirmed location have been located by their latitude and longitude. For pollution sources whose location is unknown, their spatial allocation has been carried out and a detailed emission inventory of the pollution sources has been compiled on the basis of the population ratio of each grid and GDP output ratio, which provides basis data for the air quality stimulation and policy-making for prevention and control of air pollution of urban agglomeration.
