由于城市化和经济增长，中国的氮沉降可能会增加。目前的研究考虑的是在N沉降增加的假设下的生态意义。中国大气氮沉降有趋于稳定或下降的趋势。这种高氮负荷生态系统在大气氮沉降减少情景下的潜在恢复和响应尚未得到充分的研究。本工作回顾了现有文献，考虑了生态系统中碳(C)固存、生物多样性和物种组成、土壤酸化和温室气体排放对近期氮沉降模式的可能响应。通过最新的N添加实验和模型开发，可以进一步探索N组成和内部比的潜在影响。
Nitrogen (N) deposition in China may increase due to urbanization and economic growth. Current research has considered the ecological significance under the assumption of increasing N deposition. Atmospheric N deposition tending toward levelling or declining has been observed in China. Such potential recovery and responses of high N loads ecosystems under decreasing atmospheric N deposition scenarios have yet to be adequately investigated. This work reviews existing literature to consider possible responses of carbon (C) sequestration, biodiversity and species composition, soil acidification, and greenhouse emissions in ecosystems responding to recent patterns of N deposition. Potential effects of N composition and internal ratios may be further explored through state-of-the-art N addition experiments and model development.
