| 摘 要： | 碳(C)、氮(N)、磷(P)生态化学计量比是生态系统过程及其功能的重要特征.以闽江河口的芦苇(Phragmites australis)和短叶茳芏(Cyperus malaccensis var.brevifolius)湿地为对象,开展植物活体-枯落物-土壤系统的C、N、P季节动态研究.结果表明:芦苇和短叶茳芏植物活体、枯落物和土壤年均C、N、P含量为C＞N＞P,两种湿地系统C、N含量均为植物活体和枯落物高于土壤,但与土壤P含量大小关系因植物构件差异而不同；芦苇和短叶茳芏植物活体、枯落物和土壤的C、N、P生态化学计量比表现为C∶P＞C∶N＞N∶P；芦苇湿地C∶N为枯落物＞植物活体＞土壤,短叶茳芏为植物活体＞枯落物＞土壤,而C∶P和N∶P均为枯落物＞植物活体＞土壤；C、N、P化学计量比可以反映湿地C、N、P交换过程和植物群落的生态功能.
