This paper reported the results of investigation on benthic macrofauna on mud flat in Dongzhaigang Mangrove Reserve , Hainan. Sixty eight species of benthic macrofauna , belonging to six Phyla , 34 families were found. The dominant species were Cerithidea cingulata , Batillaria cumingi , Cyclotellina remies and Potamocorbula rubromuscula of Mollusca. The mean biomass of benthic macrofaunu in summer and in winter was 133.0 g/m2 and 63.0 g/m2 , respectively. The mean densities were 106.4 ind./m2 in summer and 103. 5 ind./m2 in winter. The species diversity indexes of benthic macrofaunu in summer and in winter were 1.841 and 0.380 , respectively. The species evenness indexes were 0.514 and 0.113 , respectively. The biomass diversity indexes of benthic macrofaunu were 1.994 in summer and and 1.751 in winter. The biomass evenness indexes were 0.556 and 0.520 , respectively. The biomass , density , species diversity index and biomass diversity index of benthic macrofauna varied with season and substrate. All these values were greater in summer than in winter , greater in sand2mud substrate than in mud substrate
