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 data of macrobenthos obtained from the background investigation of the recreational eco-artificial reefs along the coast of Zhejiang in July-September 2003, the species composition of macrobenthos in the artificial reefs to be transplanted, Quantitative distribution and community structure characteristics of a detailed comparative study. A total of 176 species of macrobenthos were identified in the survey, mainly broad-leaved species with wide temperature along the coast, of which, polychaetes, molluscs and crustaceans accounted for more than 90% of the total species, constituting marine reef benthos Of the main groups. The biomass and habitat density of benthos in the proposed waters were unevenly distributed with the highest biomass and habitat density of 57.23g / m2 and 872.5 / m2, the lowest of only 0.23g / m2 and 35 / m2. Most of the benthos inferred for marine benthic diversity index and evenness are higher, indicating that the community structure is relatively stable.
