摘　　要：文中简述了大气沉降中氮的形态和来源,以及大气氮沉降的形式及其监测方法,阐明其沉降机制。从水生态系统,森林生态系统和草地农田生态系统三个方面系统阐述大气氮沉降的生态影响,在此基础上展望了该领域的研究趋势,为后续关于大气氮沉降的研究提供参考。This paper briefly introduced the forms and sources of nitrogen in atmospheric deposition as well as the form of atmospheric nitrogen deposition and its monitoring methods and clarified its deposition mechanism.The ecological impacts of atmospheric nitrogen deposition were systematically described from three aspects:water ecosystem,forest ecosystem and grassland/farmland ecosystem.On this basis,the research trends in this field were prospected,which would provide reference for the subsequent research on atmospheric nitrogen deposition.
