大亚湾潮间带软体动物分布和区系分类研究

The Study of Fauna and Distribution of Mollusc in the Intertidal Zone of Daya Bay

潮间带底栖软体动物由于其活动能力较低,在研究环境与生物的关系方面往往起着稳定的指示剂作用.笔者自1987年至1999年对大亚湾潮间带的软体动物进行了采集调查,共鉴定软体动物有241种,分属3纲60科.其中多板纲3科3种,瓣鳃纲24科117种,腹足纲33科121种.分析表明,其区系特点是以南海亚热带一热带种和东海、南海亚热带种为主要成分.

Because their lower ability of movement, mullusc in the intertidal zone are always studied as an indicator of the relationship between organisms and environment. From 1987-1999 mullusc in the intertidal zone were collected. 242 species of mollusc .belonging to 60 families, are recognized, 3 species belonging to Amphineara. 117 species belonging to Lamellibranchia, 122 species belonging to Gastrpda. The results show that tropical and subtropical warm water species distributed in the East China Sea and the South China sea are the major species in fauna of mullusc on intertidal zone of Daya Bay.
