| 摘 要： | 调查了广西珍珠港人工红海榄幼苗叶片上藤壶分布的特征。结果显示,在一年生幼苗叶片上藤壶的空间分布格局总体上为聚集分布。分布型因海水盐度的变化而变化,在高潮盐度Sh<20.21的海水区域内,藤壶趋向于随机分布,反之则表现为聚集分布。大约在分点潮高潮位以下,平均每日潮水浸淹时间超过5.6h的潮滩上藤壶的危害明显加再,影响了红海榄幼苗的正常生长。

| Abstract: | Distributional characters of barnacles on leaves of artificial R. stylosa seedlings in the Pearl Harbor of Guangxi Province were investigated in this paper. The results showed that the distributional pattern of barnacles on the leaves was generally clump and changed from random to clump with the increase of salinity. The distribution pattern of barnacles was random in the areas where high tide salinity was below 20. 21 and was clump in the areas where high tide salinity was above 20. 21. This study revealed that barnacles did great damage to R. styloxa seedlings submerged at high water of equinoctial tide for more than 5. 6 hrs every day. |
