| 摘 要： | 通过对闽江河口湿地主要植物生物量的测定与分析,结果表明,闽江河口主要植物群落的生物量季节动态规律基本一致：4月下旬返青后,5月份植物体进行营养生长,生物量较小;随着生育时期的推进,进入营养生长和生殖生长期,生物量逐渐增加,经过一段时间,而后因植株衰老、枯死体量增加,生物量又开始下降。植物体地上和地下生物量的最大值出现在8月份,互花米草群落、芦苇群落、咸草群落的总生物量的最大值分别为40.96、41.30和31.17 t·hm^-2。从主要植物群落的平均生物量来看,互花米草群落（34.04 t·hm^-2）〉芦苇群落（27.21 ·hm^-2）〉咸草群落（20.21 ·hm^-2）。

| Abstract: | Through the determination of biomass of main plant community of estuarine wetland of Minjiang river,result shows that :biomass seasonal dynamics of main plant community of Minjiang river estuary is basically identical: in late April after turning green,plant grow vegetatively in May and the biomass is smaller;with the promoting of growth stage,keeping with vegetative & reproductive growth phase,biomass increase gradually;biomass begins to decrease because of aging of the plant and increase of dead matter after a period of time.The maximum biomass above & under ground of plant appears in August.Maximum value of total biomass of community of Spartina alterniflora,Phragmites australis,Cyperus malaccensis Lam is 40.96,41.30,31.17 t·hm-2 respectively.Community of Spartina alterniflora(34.04 t·hm-2)>community of Phragmites australis(27.21 t·hm-2)>community of C.malaccensis Lam(20.21 t·hm-2)among biomass of main plant communities. |
