【摘要】 为了解人工鱼礁的生物附着状况,于2008年6月和7月,对大亚湾杨梅坑人工鱼礁区中已投放1年的混凝土礁体和铁制礁体上的附着生物进行了调查。2次调查共采集和鉴定出附着生物94种。其中,混凝土礁体附着生物种类达到73种,总生物量为27903.50 g/m~2,多样性指数为4.68,均匀度指数为0.76。铁制礁体种类达到80种,总生物量为23023.00 g/m~2,多样性指数为4.53,均匀度指数为0.72。人工鱼礁投放1年后,礁体表面100%被生物所覆盖,三角藤壶(Balanus trigonus)是人工鱼礁区占据绝对优势的种类,其优势度达到0.1464。更多还原

【Abstract】 To understand the type and extent of fouling organisms on artificial reef,the investigation was conducted within the period in May and June 2008.The fouling organisms of two materials which concluded concrete and steel reefs casting one year on artificial reef located in Shen Zhen was surveyed.The results showed that a total of 94 species were collected and identified through two investigation.Among them,the species of fouling organisms on concrete reef reached 73,the biomas,diversity index and evenness values of the communities were 27903.50 g/m~2,4.68 and 0.76,respectively.The species of fouling organisms on steel reefs reached 80,the biomas,diversity index and evenness values of the communities were 23023.00 g/m~2,4.53 and 0.72,respectively.One year after the reefs were cast,they were 100%covered by the organisms,Balanus trigonus which dominance reaching 0.1464 were the absolute advantage species.更多还原
