摘　　要： 为了对惠东人工鱼礁的投放进行评估以及观察对渔业资源的生物聚集效果,分别于2008年5月和2011年6月对惠东大星山人工鱼礁区进行了拖网和刺网的本底调查和跟踪调查。采用生物资源密度指数(D)、Margalef种类丰度指数(R)、Shannon-Winener多样性指数(H')、Pileou均匀度指数(J')来研究水域生物种群的多样性和资源密度。拖网调查结果表明,投礁后礁区游泳生物种类数、总资源密度、种类丰度指数、多样性指数均有明显的增加,分别为投礁前的1.321倍、2.070倍、1.012倍、1.084倍。刺网调查结果表明,投礁后礁区游泳生物种类数、总资源密度、种类丰度指数、多样性指数,分别为投礁前的2.571倍、7.976倍、2.399倍、2.667倍。投礁后礁区鱼蟹类成为主要的优势类群。这表明鱼礁投放后,对鱼类等的诱集效果显著,群落结构明显优化,礁区水域环境,明显改善。惠东大星山礁区的人工鱼礁增殖体系已基本形成。 The background and treasure effects of artificial reef area in Huidong were carried out in May, 2008 and June, 2011 respectively, for the purpose of ascertain the fish-aggregation effects of artificial reef of Huidong Daxing Mountain. Several indexes were chosen for better ex- planation on multiformity of biological population and resources density by biomass density index（ D）, Margalef species richness index（ R）, Shannon-Winener diversity index （ H＇ ） and pileou Uniformity index（ J＇ ）, The results of trawl net survey indicated that after deployment of arti- ficial reefs, total number of species, biomass density index, Margalef species richness index, Shannon-Winener diversity index and pileou uni- formity index of artificial reef area increased by 1. 321 times, 2. 070 times, 1. 012 times, 1. 084 times respectively. The results of gill net sur- vey indicated that after deployment of artificial reefs, total number of species, biomass density index, Margalef species richness index and Shannon-Winener diversity index of artificial reef area increased by 2. 571 times, 7. 976 times, 2.399 times, 2. 667 times respectively. These indexes were increased obviously. The fish became dominant species in tracking survey which were not abundant in background survey. It was concluded that the fish-aggregation effects are extraordinary, the resources level, community structure have improved a lot. The proliferation system of Huidong Daxing Mountain artificial reef has been engendered.
