| 摘 要： | 人为干扰下的大气氮素沉降已成为全球氮素生物化学循环的一个重要组成部分。作为营养源和酸源, 大气氮沉降数量的急剧增加将严重影响陆地及水生生态系统的生产力和稳定性。本文从大气氮沉降对土壤和水体环境、农业和森林生态系统以及生物多样性等方面综述了近年来国内外大气氮素沉降的研究现状及其对生态系统的影响, 并总结探讨了前人采用的大气沉降氮测定方法, 展望了我国大气氮沉降的研究前景。 |
| 关 键 词： | 大气氮沉降 人类活动 生态效应 测定方法 活性氮 生态系统 |

| Abstract: | Atmospheric N deposition under human influence is an important part of global biogeochemical N cycle. As an important source of plant nutrient and soil acidification, increased N deposition from the atmosphere would greatly impact production and stability of global terrestrial and aquatic ecosystems. This paper reviews recent literatures on atmospheric N deposition and the related ecological effects on soil and water environment, agriculture and forest ecosystems and biodiversity. It summarizes documented measurement methods of atmospheric N deposition. Finally, the prospected and trend of atmospheric N deposition research development in China is advanced. |
| Keywords: | Atmospheric N deposition Human activity Ecological effect Measurement method Reactive N Ecosystem |
