英文摘要	Jiangsu-Zhejiang-Shanghai (JZH) is an important industrial area and foreign trade base in China. In recent years, due to economic development and urban expansion, the emissions of volatile organic compound (VOC) have been increasing, which exacerbated the problem of formaldehyde (HCHO) pollution. The Ozone Monitoring Instrument (OMI) remote sensing has the characteristics of high spatial coverage and strong time continuity, which can enable long-term serial and large-scale dynamic monitoring of atmospheric pollutants. Based on the inversion data of OMI, the paper analyses the temporal-spatial distribution and change trend of the HCHO in JZH from 2008 to 2019, and discusses the transmission path of HCHO in combination with the backward trajectory. In addition, the degree of contribution of anthropogenic sources and natural sources to HCHO are analysed, which is the local HCHO pollution providing reference opinions on governance and atmospheric energy saving and emission reduction. The results showed that the spatial distribution of HCHO in JZH was uneven and will continue to increase in the future. Different types of artificial sources have different degrees of contribution to the study area. In addition, vegetation, temperature, and precipitation have obvious high correlations with HCHO, indicating that natural factors have an important influence on HCHO.
