摘　　要：大气氮沉降的增加作为全球变化的重要内容,反映了人类活动加剧导致的大气活性氮污染,已经并将继续对全球生态系统产生重大影响。本文简要介绍了大气氮素干湿沉降的研究方法,回顾了国内外大气氮沉降形态、数量等方面的研究进展及大气氮沉降对水体、森林、农田生态系统的影响,并探讨了该领域目前存在的问题及未来的研究重点和方向。Elevated atmospheric nitrogen （N） deposition, as important part of global change, reflects atmospheric reactive N pollution induced by accelerated human activities and has significantly impacted global terrestrial and aquatic ecosystems. In this mini-review, we introduced the concept and study approaches of atmospheric N deposition and summarized the major progress on the forms and amounts of N deposition as well as its impact on aquatic, forest and agricultural ecosystems. Finally, the shortcomings and outlook of the research area （ in particular ecological impacts of N deposition） were also discussed in the paper.
