Abstract:

碳在不同类型湿地中储藏量约占地球陆地碳总量的15%。由于全球湿地面积迅速减少,湿地生态系统正常的水循环和碳循环过程产生一定的变化,湿地生态系统的演变也可能是全球大气CO2含量升高的一个不可忽视的重要因素。气候条件是湿地碳循环生物地球化学过程的重要驱动因素,湿地特殊的生态水文过程和土壤环境条件,使得湿地碳循环具有区别于其它生态系统碳循环的特征。影响湿地中碳积累与分解过程的重要控制因子是温度、水文条件和植物群落,特别是水文条件对湿地碳循环过程影响较大。湿地土壤呼吸通量与根层土壤温度呈正相关关系,并受地表积水深度和地下潜水水位的影响,另外,洪泛作用会增加湿地CO2的排放率,湿地水文过程决定溶解有机碳的输入与输出过程。
