摘      要：The Changjiang(Yangtze)River estuary has been subject to a variety of anthropogenic pressures in recent *** assess the ecological health of the coastal benthic ecosystem adjacent to the estuary,three surveys were conducted in 2005,2009,and *** AZTI s Marine Biotic Index(AMBI)and multivariate-AMBI(M-AMBI)were used to analyse the benthic ecological status of this *** AMBI indicate that the ecological status of the coast adjacent to the Changjiang River estuary was only slightly degraded in all 3 *** contrast,the M-AMBI indicated that the ecological status was seriously degraded,a result that is most likely due to pollution and eutrophication induced by human *** assessment of the coast s ecological status by the AMBI was not in agreement with that of the M-AMBI at some stations because of lower biodiversity values at those *** analysis of the two indices integrated with abiotic parameters showed that the M-AMBI could be used as a suitable bio-indicator index to assess the benthic ecological status of the coast adjacent to the Changjiang River *** reference conditions proposed for the coast of the Changjiang River estuary should be further evaluated in future *** of local species could also provide an important reference for Chinese *** improve the reliability of AMBI and M-AMBI,further research into the ecology of local species is required to understand their arrangement in ecological groups.
