Assessment on the Macrozoobenthos Community Health in Xiamen Bay Using Macrozoobenthos Community In-dex
摘要
Abstract
[Objective]The benthic animal community health in Xiamen bay was investigated,and a suitable evaluation method was preliminarily built,by which the quality condition of benthic ecology in Xiamen bay was estimated.[Methods]Based on the materials collected from Xiamen Bay in March and June 2011,the Shannon-Weiner diversity index,Margalef richness index and M-AMBI were selected to set macrozoobenthos community index (MCI)to assess the macrozo-obenthos community health status.Furthermore,each index was given a suitable score and weighted average to count the MCI value.[Results]The macrozoobenthos community health in March was worse than that in June in Xiamen Bay.And,Tong’an Bay was presented as the worst health of macrozoobenthos community,while the eastern and western areas were presen-ted as the best in our studied areas of Xiamen Bay.A clear spatial gradient of changing commu-nity quality was found along the Jiulongjiang estuary to off shore and northern-wards areas,in-dicating that the quality status became gradually better off estuary and forward northern part.[Conclusion ]The characters of spatial and temporal distribution patterns of macrobenthic assemblages in Xiamen Bay were closely related to the combined effects of several environmental factors.It is demonstrated here that the MCI could be used to assess the health status of ma-cobenthic assemblages in Xiamen Bay.关键词
