摘要: 亚热带滨海湿地的甲烷(CH4)排放受湿地类型、季节和地区的显著影响。本研究通过对福建、浙江、上海和江苏等省(直辖市)典型亚热带滨海湿地的CH4通量比较分析，揭示了不同环境因素包括土壤有机碳含量、总氮、月均温、纬度等对CH4排放的调控机制。本地盐沼、入侵盐沼和光滩的排放通量存在显著差异，其中入侵盐沼的排放量最高。季节变化呈现出夏秋季节排放量较高的特征，主要受温度和植物生长的调节作用。研究结果为湿地CH4排放机制的理解提供了重要实验数据和理论依据，对生态学和气候变化研究具有重要意义。
Abstract: Methane (CH4) emissions from subtropical coastal wetlands are significantly influenced by wetland type, region, and season. This study, through a comparative analysis of CH4 fluxes in typical wetlands of Fujian, Zhejiang, Shanghai, and Jiangsu provinces (municipalities), reveals the regulatory mechanisms of different environmental factors—such as soil organic carbon content, total nitrogen, and temperature—on CH4 emissions. Significant differences in emission fluxes were observed among native salt marshes, Spartina alterniflora wetlands, and bare mudflats, with the highest emissions recorded in wetlands invaded by Spartina alterniflora. Seasonal variations showed higher emissions in summer and autumn, primarily regulated by temperature and plant growth. The findings provide important experimental data and a theoretical basis for understanding CH4 emission mechanisms in wetlands, which holds significant implications for ecological and climate change research.
