【 摘 要 】

Atmospheric nitrogen deposition is one of the most important elements in nitrogen biogeochemical cycles. It is not only one of the major processes for removing nitrogenous pollutants in the air, but also an important way for the ecosystem to obtain nitrogen from the atmosphere. In recent years, due to the combustion of minerals, the use of chemical fertilizers and the rapid development of livestock husbandry, human activities have led to the continuous increase of atmospheric active nitrogen concentration, which has aroused widespread concern of all parties. This paper introduces the types and sources of atmospheric nitrogen deposition and focuses on the response of atmospheric nitrogen deposition to different ecosystems.
