2005年夏季舟山群岛潮间带的生态学研究

系2005年夏季对舟山群岛12个岛屿30个断面潮间带群落生态学调查的结果。初步鉴定,物种共有97种,以软体动物和节肢动物占优势,同时,生态类群以我国沿海广温广布性种和亚热带种占绝对优势。舟山群岛夏季潮间带生物种类数量的平面分布与盐度、海岸开敞程度有关,垂直分布与潮汐有关;群落数量的分布与底质、海岸开敞程度有关。舟山潮间带生物在不同底质类型的潮间带有着明显地分带现象,同时珠带拟蟹守螺Cerithidea cingulata、节蝾螺Turbo articulatus Reeve、泥螺Bullacta exarata(Philippi)、疣荔枝螺Thais clavigera Kuster为舟山群岛潮间带腹足类的优势种。

Studies on Inter-tidal Zone Ecology of Zhoushan Archipelago During the Summer, 2005

The results of the survey are presented about the inter-tidal zone of Zhoushan Archipelago dur-ing the summer of 2005. 96 benthic species have been identified, among which Mollusca and Arthropoda are dominant socials. As a fauna nature, the eurythermous-eurytopic species and the subtropical species predomi-nate absolutely over the others. The horizontal distribution of species quantity in the summer in the inter-tidal zone of Zhoushan Archipelago is related to the salinity and the opening degree of shore, and the vertical distri-bution is related to the tide. The quantitive distribution of community is in connection with the substrate and the exposure of coast. The biological zone is clearly observed among different substrate type in the inter-tidal zone of Zhoushan Archipelago. Cerithidea cingulata, Turbo articulatus Reeve, Bullacta exarata (Philippi) and Thais clavigera Kuster are the dominant socials of Gastropoda in the aestival inter-tidal zone of Zhoushan Archipelago.
