Abstract: Volatile organic compounds (VOCs) are the key precursors that affect the formation of air compound pollution, with many sources and large differences in chemical composition. In order to meet the demand for precise control of urban scale VOCs, this study is based on the "bottom-up" anthropogenic activity level data and vegetation remote sensing data, coupled with literature research and measured VOCs source profiles, and adopts the emission factor method to develop the compilation method of urban scale high spatial resolution speciated VOCs emission inventory, which is applied in Zhumadian City, Henan Province as the research area. The results show that: (1) The inventory preparation method constructed by the Institute can obtain urban scale speciated VOCs emission inventory with high spatial resolution. According to the activity level resolution available at this stage, the inventory resolution can reach 1km × 1km and above. (2) In terms of component emissions, olefin emissions are the highest, followed by alkanes and OVOCs(oxygenated volatile organic compounds). The top 10 components of emissions are isoprene, styrene, ethyl acetate, ethylene, monoterpene, benzene, acetaldehyde, n-hexane, toluene and formaldehyde, respectively; The total amount of OFP is 366111.0 t, olefins and OVOCs are the main contributors, and the top 10 components of OFP are isoprene, ethylene, acetaldehyde, formaldehyde, propylene, monoterpene, m-xylene, toluene, styrene and 1-butene respectively; In terms of spatial distribution, the spatial distribution of VOCs emissions in the study area is significantly different. The VOCs emissions in areas with dense forests, dense industrial enterprises, and large population and road network density are higher. (3) Comparing the emission inventory results with the receptor model analysis results, it is found that the two are basically consistent in the identification of major source classes, which confirms the reliability of the list constructed by the Institute.
