中文摘要：
大气氮沉降已经并将继续对全球生态系统产生重大影响。大气氮沉降是陆源氮进入水体的重要途径,会使水体氮含量增加,富营养化加重,严重影响生态系统的稳定性。因此,大气氮沉降通量及其对水生生态系统的影响等问题值得深入探讨。介绍了国内外大气氮沉降监测网络、空间分异等方面的研究进展,总结了大气氮干湿沉降的研究方法及大气氮沉降对水体氮负荷的影响,并探讨了该领域目前存在的问题及发展趋势。
英文摘要：
Elevated atmospheric nitrogen deposition has been and will continue to impact the global terrestrial and aquatic ecosystems.The atmospheric nitrogen deposition is an important route of terrestrial nitrogen delivers into aquatic,it will increase the nitrogen content in water,aggravate the eutrophication and seriously affecting the stability of aquatic ecosystem.Therefore,it has become one of the hot issues in the atmospheric and oceanic environmental sciences.The paper introduced the concept and study approaches of atmospheric nitrogen deposition and summarized the major progress on the monitoring network and spatial distribution of nitrogen deposition as well as its impact on aquatic system.The short-comings and outlook of the research area were also discussed in the paper.
