摘　　要：This study conducted four cruises during 2014–2017 to investigate relationships between macrobenthic communities and sediment contaminations in sea area around the Zhoushan Archipelago.Fourteen sites were categorized into three groups:high total heavy metal contamination content(HHMC),high total petroleum hydrocarbon content(HTPH),and low content ratio of heavy metal contamination content to total petroleum hydrocarbon content(HMC/TPH)areas.Four main taxa of macrofauna(polychaetes,bivalves,gastropods,and crustaceans)were determined to respond to environmental factors differently.While tolerant polychaetes being the minimal impact by environmental factors,bivalves were threated by heavy metal pollutions in sediment.Additionally,body size distribution frequency demonstrated that macrofauna in the low HMC/TPH areas were less disturbed by contamination than those in the HHMC and HTPH areas.The result represented the presentation of sensitive species while tolerant species are usually considered as small size organisms.Overall,this study confirmed the hypothesis that the contamination levels of small-scale patches is indicated by the condition of macrobenthic communities.
