Based on the collected activity data and emission factors,the emission inventory for the period 2007—2014 was developed by using an appropriate estimation methods. Spatial distribution of emission inventory at 1 km resolution was estimated for the base year 2014 using and GIS techniques. Results showed that the total annual emissions of CO,HC,NO_x,PM_(2.5),PM_(10) and SO_2for Nanchang during 2007—2014 were 18.26×10~4,5.07×10~4,18.46×10~4,0.99×10~4,1.08×10~4,and 3.31×10~4t,respectively,while those from mobile source in 2014 was 2.14×10~4,0.76×10~4,1.97×10~4,0.08×10~4,0.09×10~4,and 0.55×10~4t,respectively. For on-road mobile source,gasoline passenger cars were the largest contributors for CO,HC and SO_2,accounting for 55.1%,78.5% and 56.1%,respectively,while diesel heavy duty trucks were the largest contributors for NO_x,PM_(2.5)and PM_(10),accounting for 43.2%,40% and 40%,respectively. For non-road mobile source,small tractors were the biggest contributors for CO,HC,NO_x,PM_(2.5)and PM_(10),accounting for 29.9%,26.9%,23.4%,29.5% and 29.8%,respectively. SO_2 was mainly emitted from ships with contribution of 45.1%. The areas with high pollution emissions were mainly located in Qingshanhu District,Xihu District and Donghu District.
