氮沉降驱动非线性生态系统响应，但控制功能临界点的潜在地下机制仍然知之甚少。在青藏高原某高寒草地上，利用no3 -和nh4 +进行了6个N添加水平（0-32 g N m−2年−1年，指定为N0-N32）的原位15n标记试验。总生物量随着氮素添加量的增加而增加，直到中等氮素水平（N8），然后达到平稳期，而植株总氮素吸收在3086 mg N m - 2时达到峰值，此后下降，揭示了结构生长与功能氮素获取之间的解耦合。值得注意的是，在低氮添加（N2）条件下，植物表现出从nh4 +到no3−的氮形态偏好的短暂转变，同时微生物对氮的吸收（484 mg N m−2）下降，并且它们的偏好也发生了类似的转变。这些模式加剧了植物与微生物在N2水平下对NO 3−的竞争，但随后在较高N水平下减弱。合成。我们的研究结果表明，在生物量饱和之前，氮获取策略的阈值发生了变化。我们提出植物-微生物竞争中N形态偏好模式和相关变化可以作为生态系统N饱和度的预警指标，为改善基于阈值的高寒草原养分管理提供机制见解。
