福建省南部沿海东山湾和浮头湾潮下带春秋两季大型底栖动物的生态健康评估
Ecological health assessment of benthic macrofauna in the subtidal zone of Dongshan Bay and Futou Bay along the coast of southern Fujian Province in spring and autumn
摘要
Abstract
[Objective]Dongshan Bay and Futou Bay are located on both sides of Gulei Peninsula along the coast of southern Fujian Province.The development of the Gulei Peninsula petrochemical base and the construction of Dongshanwan Zhangzhou nuclear power plant may have an impact on the ecological environment of both bays.In recent years,the dismantling of the Bachimen seawall and several aquaculture cages in Dongshan Bay has taken place,and the effectiveness of ecological restoration needs to be evaluated.To assess the distribution characteristics and ecological health status of macrobenthos communities in the two bays,macrobenthos surveys were conducted in the subtidal zones of Dongshan Bay and Futou Bay in the spring and autumn of 2020.[Methods]Eight parameters of the macrobenthos community were analyzed,including species number,density,biomass,diversity index(H'),evenness index(J),richness index(d),ATZI marine biological index(AMBI)and multivariate AMBI(M-AMBI).These parameters were analyzed by variance analysis,cluster analysis and non-metric multi-dimensional scaling(nMDS)analysis.The dominant species in the macrobenthos communities of the two bays,including the inner bay and estuarine zones,were analyzed using the relative importance index(IRI).[Results]Analysis of variance showed no significant difference between Dongshan Bay and Futou Bay in the eight community parameters of benthic macrofauna:species number,density,biomass,H,J,d,AMBI,and M-AMBI.In Dongshan Bay,macrobenthos density in the inner bay was significantly lower than that in the estuary(P＜0.05),while J value in the inner bay was significantly higher than that in the estuary(P＜0.05).In Futou Bay,species number,H',d and M-AMBI in the inner bay were all significantly lower than those in the estuary(P＜0.05).Cluster and nMDS analysis indicated the presence of two main macrobenthos communities in the subtidal zone of both bays.The first community had a higher proportion of sampling stations in autumn,while the second community had a higher proportion of sampling stations in spring.The IRI analysis showed seasonal and spatial variations in the dominant species of Dongshan Bay and Futou Bay.In both bays,the first dominant species was Amaeana trilobata in spring,but in autumn,it was Notomastus latericeus and A.trilobata,respectively.The first dominant species in Futou Bay in spring and autumn is A.trilobata,but the first dominant species in the inner bay and bay estuary of Dongshan Bay,and the bay estuary of Futou Bay was different in spring and autumn.The average values of the three biological indices(H,AMBI and M-AMBI)showed that both bays were in a slightly disturbed state in both seasons,with the estuary of Futou Bay showing better ecological health than its inner bay.[Conclusion]In both spring and autumn,the number of macrozoobenthos species,H',d and M-AMBI in the inner bay were significantly lower than those in the estuary of Futou Bay,while the multivariate marine biological index was significautly higher,indicating better ecological health in the estuary than the inner bay.These findings suggest that macrozoobenthos communities in Dongshan Bay and Futou Bay were in a slightly disturbed state,with the estuary of Futou Bay maintaining better ecological conditions than its inner bay.关键词
