黄河三角洲湿地是我国最完整、最广阔、最年轻的湿地生态系统。由于人类活动的影响，湿地面临退化的风险，迫切需要进行生态恢复。湿地因其独特的水热效应和温室气体代谢过程，是全球变化的影响区和响应区。本研究选取了5种典型盐沼植物群落，研究了盐沼植物群落的温室气体排放特征。结果表明，该地区温室气体排放，尤其是CO2和CH 4的排放具有明显的空间变异性。HW 4采样点的CH 4和CO2排放浓度最高，在静态不透明室中分别达到691.6和1.32 mg/m3。5个植物群落的CH 4和CO2年排放总量分别约为1.20 × 104 t a-1和18.4 × 104 t a-1。土壤水分与CH 4排放量呈正相关，与CO2排放量呈负相关。土壤中Fe和Mn含量之间呈线性相关（y= 0.0196x +0.0252，R2 = 0.9872）。
The Yellow River Delta wetland is the most integrated, broadest, youngest wetland ecological system in China. Due to the affection by human activities, the wetland is under a degraded risk and urgently require for ecological restoration. Moreover, the wetland is an influenced and responsive region of global change because of its unique water-heat effect and greenhouse gas metabolic process. In this study, five typical salt marsh plant communities were selected to study the characteristics of greenhouse gas emission of the wetland. The results indicated that the greenhouse gas emission, especially for the CO2and CH4, showed a distinctly spatial variation. The sample site (HW4) discharged the maximum emissions concentration of CH4and CO2, reaching 691.6 and 1.32 mg/m3in the static opaque chamber, respectively. The total annual emissions of CH4and CO2were approximately 1.20 × 104t a−1and 18.4 × 104t a−1in the five plant communities. It was also found that the relationship of the soil moisture to CH4emissions was positive correlation, but that to CO2emissions was negative correlation. In addition, there was a linear correlation (y= 0.0196x + 0.0252,R2= 0.9872) between the content of Fe and Mn in the soil.
