Climate warming and increasing nitrogen (N) deposition have influenced plant nutrient status and thus plant carbon (C) fixation and vegetation composition in boreal peatlands. Phenols, which are secondary metabolites in plants for defense and adaptation, also play important roles in regulating peatland C dynamics due to their anti-decomposition properties. However, how the phenolic levels of different functional types of plants vary depending on nutrient availability remain unclear in boreal peatlands.

东北泥炭地植物酚含量及其随氮素利用的变化

气候变暖和氮（N）沉积增加已经影响了植物的养分状况，从而影响了北方泥炭地植物的碳（C）固着和植被组成。酚类是植物防御和适应的次要代谢产物，由于其抗分解特性，在调节泥炭地C的动态中也起着重要的作用。然而，在北方的泥炭地上，不同功能类型的植物的酚类水平如何根据养分的可获得性而变化尚不清楚。
