Abstract：The data of this research (national formaldehyde column concentration in 2016) was extracted from OMIHCHO (OMI/Aura Formaldehyde[HCHO] Total Column Daily L2Global Gridded 0.25degree×0.25degree V3). The characteristics of the spatial and temporal distribution of formaldehyde column concentration was analyzed, and then several correlated factors such as temperature, rainfall, vegetation coverage and human activities in various provinces and cities in China were discussed. Results were listed as following:the spatial distribution of formaldehyde column concentration is very unbalance was China. The formaldehyde column concentration was high in the eastern and southeast areas, while the western and northwestern parts of China show relatively low values. The lowest monthly average formaldehyde concentration was 8.31×1015molec/cm2 in October and the highest was 11.87×1015molec/cm2 in June. If the mean of formaldehyde concentration was arranged by the seasons from high to low, it would be summer, spring, winter and autumn. Concerning of correlation between meteorological factors (temperature, rainfall and vegetation) and formaldehyde column concentration, all results showed the spatial difference, but the formaldehyde column concentration was most influenced by the temperature; the rainfall caused a certain degree of formaldehyde elimination; and the vegetation significantly increases the concentration of formaldehyde column in the eastern and southeastern regions. There was also a significant correlation among the concentration of formaldehyde and the regional GDP, industrial value and the increase of motor vehicle ownership of various regions. The industrial added value had the highest correlation with formaldehyde, this conclusion confirms that industrial and automobile emissions was the main sources of formaldehyde.
