Abstract:In order to have a good command of the situation of air pollution in Jingzhou Economic/Technological Devel-opment Zone,the activity levels were acquired by means of data collection and field surveys,and the emission factors were selected through literature retrieval.Thereby the 1 km×1 km-gridded emission inventory of nine air pollutants from 10 kinds of sources in the Development Zone in 2019 were set up basing on the ArcGIS technology.As a result,the findings of the study showed that the total emission of SO2,NOx,CO,VOCs,NH3,PM10,PM2.5,BC,and OC in the Development Zone was 850.4,2 407.1,4 584.0,4 848.3,107.7,8 602.1,4 485.3,57.8,and 159.6 tons,respectively;and the vehicle sources(43.8%)were the major contributors to NOx emissions,while the stationary combustion sources were the main CO discharge source,accounting for 81.5%of the total CO emissions.In addition,the technological process sources were the major contributor of SO2,VOCs,PM10,PM2.5 and OC,accounting for 50.9%,69.0%,85.6%,85.5%,and 83.8%respectively,and agricultural sources were one of the important sources of NH3(32.8%of the total).On the other hand,dust sources merely accounted for 11.5%of PM10 and 10.1%of PM2.5 emissions.
