摘要
底栖动物和水生维管束植物是鱼类良好饵料及水环境监测的天然资源。在舟山尚缺少有关它们的资料。作者于1982年4月至1983年10月对舟山淡水生物区系进行调查的同时；对舟山不同水系的底栖动物和水生维管束植物作了研究，现报道如下：
This paper presents the results of limnological survey of Zhoushan Archipelago during 1982-1983.The benthon in the waters of zhoushan Archipelago contains 126 species Zooben-thos and 43 species of Macrophtes.The larvae of Chironomidae were the dominant both in the view of species number and individual number. Only a few of species of Molluses were found among which Lamellibrachia was especially poor. A small number of species of Macrophytes were observed, the biomass of which usually appeared relatively low.The analysis of variance and multiple comparison show the diversity in zoobenthos varies markedly in different types of water bodies, but not obviously in the same type water bodies in different seasons.
