Effects of Vegetation Harvest on CO2 and N2O Emissions from Sediments in a Typical Coastal Wetland

  • 摘要: 为了揭示冬季滨海湿地植被收割对其沉积物中温室气体释放的影响,以长江入海口典型滨海湿地——崇明东滩为研究对象,观测季节性(冬季)植被收割(分别于收割后第0天、第10天、第30天、第60天采样)与不收割条件下芦苇(Phragmites australis)、米草(Spartina alterniflora)、芦苇-米草交互带和光滩沉积物中CO2与N2O的释放特征. 结果表明:①米草和芦苇-米草交互带植被收割并未增加沉积物中CO2的释放(P<0.05),但芦苇收割可能会增加N2O的释放(P<0.05),说明植被收割对湿地沉积物中CO2和N2O释放的影响与植被类型密切相关. ②与芦苇带相比,米草和芦苇-米草交互带沉积物中CO2累积释放量分别高出12%~57%和17%~43%,但芦苇植被覆盖下沉积物中N2O累积释放量分别比二者高出11%~81%和8%~95%. 可见,米草和芦苇-米草交互带沉积物碳的呼吸损失明显高于芦苇带,但芦苇植被覆盖下沉积物中N2O逸失量相对较高. ③4种植被类型下,沉积物中N2O累积释放量为0.1~0.4 mg/kg,CO2累积释放量则高达1 024~2 645 mg/kg. 因此,冬季滨海湿地植被收割不会显著增加N2O的温室效应,但选择性收割米草有望减少沉积物碳的呼吸损失.
