广西红海榄群落的生物量和生产力

Biomass and Productivity of Rhinophora stylosa Community in Yingluo Bay of Guangxi, China

讨论了广西合浦县山口英罗湾70年生的红海榄群落的生物量和生产力,测定结果表明,红海榄群落的生物量为29158.0g/m^2,其中地上部为19621.2g/m^2,地下部为9536.8g/m^2,支柱根的生物量占群落总生物量的25.28％,是红海榄极为重要的组成部分,也是红海榄不同于其他植物的特点,该群落1989年的净初级生产量为1537.1g/m^2,其中年凋落物量为631.3g/m^2。
