Macrobenthos was investigated at the Pearl River Estuary ocean dumping site in March and July 2006. Differences in species quantity, abundance, biomass, the dominant species and species diversity index of mactobenthos were analyzed inside and outside the dumping site. The results showed that the ocean dumping may have decreased species quantity, abun-dance, biomass and species diversity of mactobenthos. AMBI and BENTIX indices revealed that macrobenthic communities indicated slight interference at the ocean dumping site. Macrobenthic communities showed greater interference in March than in July. ABC (Abundance/biomass comparison) revealed that macrobenthic communities had slight or moderate interference at the ocean dumping site.
Key words: Pearl River Estuary; macrobenthos; community; ocean dumping site
