Based on the data of shrimp resources sampled in the inshore waters in the southern Haizhou Bay (34.60°-35.00°N，119.40°-119.90°E) in May(spring), September(summer) and December(winter), 2009, the shrimp species composition, dominant species, ecological groups, diversity, and seasonal variety of the community were analyzed. The results showed that the shrimp community here possessed typical inshore warm temperate characteristics as part of the Southern Yellow Sea. With Alpheus japonicas, Palaemon gravieri, Metapenaeopsis dalei as major dominant species, the shrimp community in spring and winter had got remarkable warm temperate characteristics, while in summer the warm water characteristic was increased with Metapenaeus ensis, Parapenaeopsis tenella and Trachypenaeus curvirostris as dominant species. 19 species of shrimps were identified in the survey, with 18, 9 and 9 species in winter, spring and summer, respectively. In winter, the diversity index (H′) of biomass for shrimps was the highest, and its k dominant curve went more smoothly, while the indexes were lower in spring and summer, which suggested the community structure in winter was more steady. With the CLUSTER and nMDS analysis, the division of shrimp communities in winter was relatively obvious, with three main assemblages, which were inshore assemblage, Guan Estuary assemblage and eastern outside assemblage. This division was relatively stable as the assemblages were in great conformity with the environment background.
