摘要
本文系1981年4月～1984年12月对舟山海区沿岸潮间带调查的结果。已鉴定藻类51种,动物224种。区系性质以我国沿海广温性分布种和亚热带种占绝对优势。区系的暖水性质自近岸向外海明显增强,这与台湾暖流对本区的影响有关。绝大多数亚热带广分布种的北界不超过长江口。种类的水平分布与底质、盐度、海岸开敞程度和海流有关,垂直分布与潮汐和海岸开敞程度有关。据水文、地貌及生物学特征,舟山潮间带可分为近岸区、近外海区和外海区三个生态区。
1.The results of the survey are presented in tidal zone of Zhoushan seas during April 1981 to December 1 984.51 species of algae and 224 species of animal have been identified. As a faunal nature, the subtropical species predominate absolutely over the others. The warm water nature of the fauna becomes more evident from near-shore to off coast, this is related to the influence of the Kuroshio warm current.
2.The vertical distribution of biological species is related to the tide and the opening degree of coast. The horizontal distribution is related to the saltness and the opening degree of coast.
3. According to the hydrography, geomorphology and biological characteristics, Zhoushan tidal zone can be devided into three ecotopes: neritic zone, near off coast zone and off coast zone.
