摘  要：
随着我国经济快速发展,近年来大气活性氮排放量呈持续增长的趋势,研究表明,我国多地大气活性氮沉降量已经超过临界值。活性氮来源于化石燃料燃烧、畜牧家禽排放以及农业氮肥挥发、交通废气的排放等。沉降到生态系统的氮一部分可作为营养源提供给农作物,而过量的氮沉降会对生态系统及空气环境产生诸多消极作用。我国对地区大气活性氮监测的研究越来越多,主要是对农田、城市、水体及森林生态系统氮沉降情况的监测。重点阐述活性氮干湿沉降的研究方法及我国不同地理分区大气活性氮干湿沉降的时空特征。

摘  要：
With the rapid development of China's economy, recently, considerable active nitrogen was emitted into atmosphere due to fossil fuel combustion, livestock and poultry emissions, agricultural nitrogen volatilization and traffic exhaust emissions. Some studies showed that the amount of active N deposition from the atmosphere had exceeded the critical value in China. The part of N deposited into ecosystem could be a nutrient source to crops, and high N deposition has caused a series of environment risk. More and more studies were carried out on the monitoring of atmospheric active nitrogen in China, mainly on the nitrogen deposition in farmland, city, water body and forest ecosystem. This paper focused on the research methods of dry and wet deposition of active nitrogen and the spatial and temporal characteristics of atmospheric N deposition in different geographical regions of China.
