| 摘 要： | 由于化石燃料的燃烧、含氮化肥的使用以及畜牧业等人类活动的影响，向大气中排放的含氮化合物数量不断上升，从而引起大气氮沉降的增加，使得某些陆地生态系统出现氮饱和现象。丈章综述了全球氮沉降与陆地生态系统氮饱和现状，探讨了氮饱和对植物光合作用、养分平衡和抗逆性的影响机制。

| Abstract: | Human activities such as combustion of fossil fuels, production and application of nitrogen fertilizer, and intensive agriculture and stockbreeding, have significantly elevated the reactive nitrogen concentration in the atmosphere, leading to nitrogen accumulation, and even nitrogen saturation in some terrestrial ecosystems. The status of global nitrogen deposition and the concept of nitrogen saturation are reviewed, and the research progress concerning ecophysiological response of the plants to nitrogen saturation, including photosynthesis, nutrient absorption and stress resistance, are described and discussed in details. |

| Keywords: | nitrogen deposition nitrogen saturation plant ecophysiology photosynthesis nutrient balance stress resistance |
