| 摘要: |
| 2012年春季和夏季大潮期间在舟山嵊泗10个无居民海岛布设10个岩相潮间带断面进行底栖动物样品采集。经实验室鉴定，春季共采集到23种潮间带底栖动物，其中软体动物16种、甲壳动物6种、腔肠动物1种，潮间带底栖动物的平均生物量范围为907.52~3 402.43 g/m2，优势种为鳞笠藤壶、厚壳贻贝和日本菊花螺；夏季共采集到34种潮间带底栖动物，其中软体动物23种，甲壳动物8种，腔肠动物、海绵动物和多毛类各1种，潮间带底栖动物的平均生物量范围为358.09～4 790.95 g/m2，优势种为厚壳贻贝、疣荔枝螺和紫贻贝。潮间带底栖动物的区系按温度性质可分为沿海广温广布种、亚热带种、暖温带种三大主要类群。春季和夏季潮间带底栖动物的多样性指数均较低，分布不均匀。通过ABC曲线分析发现，潮间带底栖动物已受到一定程度的环境污染或人为干扰。 |

| Abstract: |
| Macrobenthos samples were collected from 10 rocky intertidal zones in 10 uninhabited islands during spring and summer in 2012 in Shengsi，Zhoushan.23 species of Macrobenthos were collected in spring，including 16 species of Mollusca，6 species of Arthropoda and 1 species of Coelenterate.The average biomass range was 907.52 g/m2 to 3 402.43 g/m2，and the dominant species were Tetraclita squamosa squamosa，Mytilus coruscus，Siphonaria japonica.34 species of Macrobenthos were collected in spring，including 23 species of Mollusca，8 species of Arthropoda，each 1 species of Coelenterate，Porifera and Polychaeta.The average biomass range was 358.09 g/m2 to 4 790.95 g/m2 and the dominant species were Mytilus coruscus,Thaisclavigera and Mytilus galloprovincialis.According to temperature property，the macrobenthos in the rocky intertidal zone can be divided into three major groups，coastal eurythermic cosmopolitic，subtropical and warm temperate species.The diversity index of benthic animals was low in the intertidal zone in spring and summer，and its distribution was not even.ABC curve analysis found that，the macrobenthos in intertidal zone had been in a certain degree of pollution of the environment or human disturbance. |
