摘要
根据2003年7￣9月在浙江沿岸休闲生态型人工鱼礁拟投海域开展的本底调查所获的大型底栖生物等资料,对各人工鱼礁拟投海域大型底栖生物的种类组成、数量分布和群落结构特征进行了详细的比较研究。调查共鉴定176种大型底栖生物,主要为沿岸广温广布种,其中多毛类、软体动物和甲壳动物占总种数的90%以上,构成了浙江沿岸人工鱼礁拟投海域底栖生物的主要类群。各拟投海域底栖生物的生物量和栖息密度分布不均匀,最高生物量和栖息密度分别为57.23g/㎡和872.5个/㎡,最低仅0.23g/㎡和35个/㎡。大部分拟投海域底栖生物的多样性指数和均匀度都较高,表明其群落结构比较稳定。
Based on the findings data of macrobenthos in coastal waters of Zhejiang where the artificial reef would be put into from Jul to Sep in 2003,detailed analysis and researeh have been earried out in detail on the macrobenthos varieties, quantitative distribution, eommunity strueture features in these areas. 176 speeies have been identified, most of which are eurythermal and dispersed species. According to the investigation, the number of filose, molusk and crustaeean aeeounted for 90 % of the total speeies and they eonsisted of the main speeies of benthon in the investigated areas, although the biomass and density of benthon were unevenly distributed. The highest of biomass and density were 57.23 g·m^-2 and 872.5 ind ·m^-2m-2 respectively, and the lowest were only 0.23 g·m^-2 and 32 ind ·m^-2.However, the eommunity strueture of benthon were relatively stable because of the high diversity index and even level.
