Wetlands provide a habitat for the symbiosis of multiple plants and play a significant role in global N₂O emissions. The metabolic traits and effects on microorganisms, which regulate the conversion of nitrogen to N₂O, varies with plant species. The frequent occurrences of cyanobacterial blooms in wetlands can also have a positive or negative effect on denitrification, entangling N₂O emissions. In situ observations of the Dongting Lake reveal that the fluxes in N₂O emissions vary with the vegetation. Maximum emissions occurred in the mud flat, while the zone with the minimum emissions was populated with carex. In 210-day batch cultures, the addition of cyanobacteria synergistically enhanced N₂O production during the degredation of phalaris and reed. The abundance of the nirS and nirK genes decreased over time except in the phalaris-algae group. To mitigate the N₂O emissions from wetlands, the macrophyte communities need to be protected, and the cyanobacterial blooms need to be avoided by reducing the nitrogen pollution.

湿地为多种植物的共生提供了栖息地，在全球 N ₂ O 排放中发挥着重要作用。调节氮向 N ₂ O 转化的微生物代谢特征和影响因植物种类而异。湿地蓝藻水华的频繁发生也可能对反硝化产生积极或消极的影响，使 N ₂ O 排放纠缠不清。洞庭湖的实地观测表明，N ₂ O 排放通量随植被的变化而变化。最大排放量出现在泥滩中，而排放量最低的区域则充满了苔藓。在 210 天的分批培养中，蓝藻的添加协同增强了 N ₂法拉里斯和芦苇降解过程中的O产生。nirS 和 nirK 基因的丰度随着时间的推移而下降，但在雉藻组中除外。为了减轻湿地的 N ₂ O 排放，需要保护大型植物群落，并通过减少氮污染来避免蓝藻大量繁殖。
