Abstract:

In order to study the emission and temporal and spatial distribution characteristics of volatile organic compounds (BVOCs) from natural sources in Beijing, Tianjin and Hebei regions in recent 20 years, based on five periods of China's land use data obtained from satellite remote sensing interpretation in 2000, 2005, 2010, 2015 and 2020, this paper calculates and obtains the emission and emission composition of BVOCs from cities and counties in Beijing, Tianjin and Hebei, At the same time, the temporal and spatial distribution of BVOCs emission in Beijing Tianjin Hebei region in recent 20 years is analyzed The results show that the average total emission of BVOCs in Beijing Tianjin Hebei region in recent 20 years is 764000 T/A, of which the average total emission of Hebei Province, Beijing and Tianjin are 591100T/A, 152900T/A and 20000t/a respectively; According to the analysis of emission composition, the average total emission of ISOP is 168000T/A, accounting for 21.99% of the total emission, the average total emission of TMT is 296200T/A, accounting for 38.77% of the total emission, and the average total emission of OVOCs is 299700T/ A, accounting for 39.23% of the total emission According to the analysis of emission time characteristics, the BVOCs emission in Beijing Tianjin Hebei region is the lowest in winter and the highest in summer The spatial distribution of BVOCs emissions is closely related to land use types and vegetation distribution. There are significant differences in the contribution of BVOCs emissions from different land use types. The average BVOCs emissions from forest land, cultivated land and grassland in Beijing Tianjin Hebei region in recent 20 years are 603300T/A, 127800T/A and 23100T/a respectively, accounting for 78.90%, 16.79% and 3.04% of the total emissions respectively The spatial emission distribution of BVOCs in Beijing Tianjin Hebei region is obviously different, and the overall emission in the north and northeast is significantly higher than that in the South and Southeast This study can provide research ideas for the calculation of BVOCs, and provide relevant basic data for air pollution control in Beijing, Tianjin and Hebei. © 2022, Editorial Board of China Environmental Science.
