英文摘要 | The ecological problems caused by dry and wet deposition of atmospheric nitrogen have been widespread concern in the world. In this study, wet and dry atmospheric depositions were monitored in plant growing season in the coastal zone of the Yellow River Delta (YRD) using automatic sampling equipment. The results showed that SO42- and Na+ were the predominant anion and cation, respectively, in both wet and dry atmospheric depositions. The total atmospheric nitrogen deposition was similar to 2264.24mg m(-2), in which dry atmospheric nitrogen deposition was about 32.02%. The highest values of dry and wet atmospheric nitrogen deposition appeared in May and August, respectively. In the studied area, NO3- -N was the main nitrogen form in dry deposition, while the predominant nitrogen in wet atmospheric deposition was NH4+ -N with similar to 56.51% of total wet atmospheric nitrogen deposition. The average monthly attribution rate of atmospheric deposition of NO3- -N and NH4+ -N was similar to 31.38% and similar to 20.50% for the contents of NO3- -N and NH4+ -N in 0-10 cm soil layer, respectively, suggested that the atmospheric nitrogen was one of main sources for soil nitrogen in coastal zone of the YRD.; The ecological problems caused by dry and wet deposition of atmospheric nitrogen have been widespread concern in the world.
