| 摘 要： | 研究了广西英罗港红树林区向海林带不同树龄的桐花树茎上白条地藤壶的分布特征。结果表明，白条地藤壶在茎上的附着高度（h)随树龄和树高增大而增大。在最大树龄17龄植株上平均达到182cm，此高度为潮高约512cm海水才能浸及，在一年中约有将近90％的时间暴露在空气中。附着高度（h)与树高（H）比值h/H以5龄树最大，达91．9％。树层最大密度达46600Ind/m^2，最小为172Ind/m^2。在同一树龄的不同树层，密度表现为先随树高增大逐渐增大，达到最大密度后又下降。在不同树龄的同一树层，密度高低变化，分布一般出现多个峰。白条地藤壶最适宜附着和生长在桐花树茎上100－120cm树层（浸及此树层的海水潮高约为430－450cm)。树层最大生物量为1719．05g/m^2，最小为5．39g/m^2。生物量分布与密度的相似。

| Abstract: | This paper deals with the distribution characte ristic of Euraphia withersi attached to the stems of different-aged Aegiceras corniculaum trees on the seaward forest zone of Yingluo Bay mangrove area in Guangxi. The results show that the attaching heights ( h ) go up with the tree ages and the wee height ( H ). The attaching height of 17-year-old trees ( the oldest ones ) reaches 182 em, which can be immersed in the seawater of about 512 cm tidal height and is exposed in the air over about 90 % of the time of a year. The ratio h/H of a 5-year-old tree reaches the highest value of 91.9 %. The highest density of tree layers is 46 600 Ind/m2, and the lowest only 172 Ind./ m2. As to the different tree layers of the same tree ages, the densities go up with the tree heights firstly and then descend after the highest density. As to the same tree layers of different tree ages,the densities usually have several peaks. The tree layer of 100-to-120-cm, which can be immersed in the seawater of about 430-to-450-cm tidal height, is the most suitable for the attachment and growth of E. withersi. The highest biomass of the tree layers is 1 719.05 g/m2, and the lowest only 5.39 g/m2. The distribution of biomass is similar to that of density. |
