小竹山岛人工鱼礁区大型底栖动物群落结构的初步研究
Preliminary study on the community structure of macrobenthos in the artificial reef area of Xiaozhushan Island
摘要
Abstract
To investigate the variation of the macrobenthos community structure following the placement of artifi-cial reefs in Xiaozhushan Island,eight voyages of macrobenthos surveys were conducted from 2017 to 2020 in the reef,adjacent,and control areas to Xiaozhushan Island.The species composition,dominant species,abundance,biomass,and biodiversity on Xiaozhushan Island were investigated.The interannual variation in the macrobenthic community structure was compared between the years.The abundance/biomass curves were used to explore the stability of the macrobenthic communities.The results showed that 72 macrobenthic species were identified,in-cluding 45 species of Polychaeta,16 species of Crustacea,8 species of Mollusca,and 3 species of Echinodermata.Simultaneously,the number of species increased by 15 during the fourth year(2020)compared with the first year(2017)after casting the reefs.Additionally,more species were detected in the reef area than in the adjacent and control areas.There were interannual fluctuations in the composition of dominant species,but Polychaeta was the dominant group.The biomass and abundance of macrobenthos increased annually and were significantly different over the four years.However,no significant difference was detected between the areas.The annual average biomass increased from 2.11 g/m2 to 4.38 g/m2,and the annual average abundance increased from 289.31 ind./m2 to 764.14 ind./m2.The Shannon-Wiener diversity index,the Margalef richness index,and the Pielou evenness index of macrobenthos did not differ significantly among the years or the areas.The CLUSTER results showed that the similarity of the macrobenthic community structure was low over the years,and the distribution pattern of the macrobenthic community varied between the years.The two-factor similarity analysis indicated significant differ-ences in the macrobenthic community structure in the surveyed sea area among the years(P＜0.01)but no signifi-cant differences among the areas(P＞0.05).The results of the similarity percentage analysis showed that Sigambra bassi,Lumbrineris longiforlia,Mediomastus californiensis,and Nephtys oligobranchia were the key species that added to the differences in the community during the surveys.The abundance/biomass curves indicated that no dis-turbance to the macrobenthic community occurred during the investigation period,and the macrobenthic communi-ties stabilized with increased reef casting time.关键词
