| 摘要: |
| 浅海岩礁环境系高生产力区,在中、高纬度海域中,由大型海藻和大叶藻(Zosteramarina)所构成的初级生产力常为浮游植物初级生产力的数倍(Miller et al.,1971)。同时,此种环境又是以大型藻类或有机碎屑为食物的珍贵海产品鲍鱼(Haliotis)、刺参(Stichopus)、海胆(Strongylocentrotus)等的栖息场所和采捕作业区;还是一些优质鱼类星鳗( Astroconger myriaster)、鲈(Lateolobrax japonicus)等的藏匿场所和游钓渔业的渔场;重要经济藻类石花菜(Gelidium)等也在此环境中定着、生长。所以,浅海岩礁的资源开发前景很好。为了促进上述珍贵海产品的增、养殖生产和发展游钓渔业,有必要对浅海岩礁底栖生物群落的结构、功能进行系统研究,以便为岩礁区的资源开发和海岸带环境保护提供科学依据。为此,中科院海洋研究所在1987年初步调查的基础上,1992年以灵山岛为点,对水下岩礁环境和生物群落进行了系统的调查。本文主要分析浅海岩礁底栖生物的群落特点。 |

| Abstract: |
| This paper presents the results of the 1987 and 1992 ecological studies on the macrobenthic community in the rocky coastal waters off Ling Shan Island.In the two surveys 49 species of macrobenthos were collected with scuba.They included seaweeds (9), seagrasses (1), molluscans (18), echinodermates (7),crustaceans (10) and other invertebrates (4). Zostera marina, Asterina pectinifera and Chlorostoma rustica were dominant species in these two surveys. Hemicentrotus pulcherrimus was abundant in 1987, but its number decreased in 1992. The number of Stichopus japonicus and Haliotis discus hannai decreased more remarkably in 1992 than 1987, because of. increased. over-fishing. The biomass of macrobenthos was high, being X=740 g/㎡. The biomass of seaweeds, echinodermates and molluscans were 538.1 g/㎡, 181.5 g/㎡ and 19.3 g/㎡ respectively and constituted 72.7%, 24.5% and 2.6% of the total biomass respectively.The biomass of other group was lower. |
