Macrobenthic functional group analysis of ecological health of the intertidal artificial oyster reefs in the Yangtze Estuary, China

The functional groups and the ecological health of a constructed oyster reef were investigated during April 2016 to October 2017 in Yangtze estuary. data long-term monitoring program (14 years) confirmed feasibility creating an artificial One or two absent from moderate salinity conditions (5.17% - 8.73%), while macrobenthos group species richness, abundance, biomass greatest under high conditions. feeding evenness index ( j FD ) showed that 14 years after construction, ecosystem reefs good high, was better Ecological lower levels salinity, possibly due absence some groups. Redundancy analysis indicated associated with changes substrate factors. Our study construction is feasible has positive effect on estuarine health.
