Abstract: In order to understand the characteristics of atmospheric nutrient deposition, measurements of dry and wet depositions of nitrogen and phosphorus were made at Daya Bay in Huizhou during spring and summer. Results showed that the average atmospheric fluxes were 257.45 and 1.79 kg·km-2·month-1 for TN and TP, respectively. Wet deposition had a larger contribution to the total flux than dry deposition for both N and P species. N species showed different variation regularity during the study period; dry deposition fluxes were higher in summer and lower in spring, while wet deposition fluxes showed the opposite trend. For P species, both dry and wet depositions showed no significant difference. With the effect of rainfall and atmospheric transmission caused by monsoon climate and regional pollution, the nutrients in the atmosphere existed mainly in the form of NO3--N. N species were the main controlled target of air pollutions at Daya Bay.
