Abstract：The factor separation technique was used as a tool to quantify the pure and synergistic contributions from emissions of anthropogenic nitrogen oxides (NOx), anthropogenic and biogenic volatile organic compounds (AVOCs, BVOCs) to the surface ozone concentrations of 2000 based on the regional air quality model (RAQM). photochemistry played an important role in the formation of daily maximum ozone. The emission impacts show significantly seasonal and regional difference. In most areas of Northern China, the largest contribution occurred in summer, while in the south of China (below 30°N) it was influenced by the Asian monsoon system and was smallest in summer. The interaction between AVOCs and NOx, BVOCs and NOx enhanced ozone concentrations. The synergistic contribution between AVOCs and NOx displayed a distinct seasonal cycle and had a summer minimum in most areas of Southern China. The interaction between BVOCs and NOx showed much difference in north and south China. In spring the higher value appeared in the south, while the interaction had a summer maximum in the north. This suggests that difference in locations and seasons should be considered besides emissions of NOx and VOCs in O3 reductions.
