摘要
浙江省海岛潮间带生物调查,共获潮间带生物769种,以软体动物(231种)居首,次为甲壳动物(139种)。生态类群以广温广布性种和亚热带性种为主。种类多样性的分布是浙南海区>浙中海区>浙北海区;不同类型底质的分布是岩礁>沙泥滩>沙滩;不同生境的分布是开敞海岸>屏蔽海岸>河口;不同潮区的分布是中潮区>低潮区>高潮区;季节分布是春季>秋季。
The results of the survey to inteffidal zone of Zhejiang Islands from April 1990 to April 1991 arepresrnted. A total of 769 species are idenfified, 231 species of molluscs and 139 species of crutanceans. As afaunal nature, the eurytherous - eurytopic species and subtropical species predominate over the other. Thespecies number is larger in the sounth islands of Zhejiang. The horizontal distribution of species number islarger on rocky shore than that on muddy shore and sandy shore. The characteristics of the composition ofspecies are mainly related to environmental factors, such as sediments from, tidal flow and sheltered degree. The vertical distribution of biological species are also discussed.
