Abstract To explore the spatiotemporal variation in N₂O in typical coastal zone and its main controlling factors under weak hydrodynamic conditions, water samples were collected from coastal rivers and wetlands (Daqing River-Duliujian River-Beidagang wetland) in July and August (Summer) and November (the beginning of Winter) in 2019. The results show that the concentration of N₂O varied between 0.4~184.5nmol/L. The saturation of N₂O ranged from 7.2%~2740%, and 90% of the samples were oversaturated, indicating that the study area was a potential source of N₂O. The N₂O release flux at the water-gas interface ranged from -0.3~6.7μmol/(m²·h), while the N₂O exchange flux in summer was higher than that in winter. The study also found that the N₂O concentration fluctuated significantly before and after rainfall, and the variation in N₂O ranged from -15.2~63.9nmol/L at same sites before and after rainfall. The average increase in N₂O concentration was significantly higher in the upper reaches (22.1nmol/L) than in the downstream (1.3nmol/L), indicating that rainfall drove the transportation of nitrogen species and accelerated N₂O release. The salinity and NO₃^--N concentration had significant effect on N₂O concentration. The N₂O emission factor of the tributaties under the weak hydrodynamic conditions in coastal zone was estimated to be 0.0073, higher than the default value of 0.0026 defined by IPCC. Therefore, the N₂O budget in the coastal zone may underestimate the indirect N₂O emissions by using the IPCC threshold value.

Key words： N₂O coastal zone weak hydrodynamic river Bohai Bay emission factor
