摘　　要：１９９５年１１月和１９９６年４月两次对青山水库的浮游植物进行研究，共鉴定藻类５８属１０１种，依次为绿藻门３９种，硅藻门２４种，蓝藻门１３种，裸藻门９种，甲藻门６种，隐藻门和金藻门各５种。其中多污水体指示种５种，ɑ－中污水体指示种２４种，β－中污水体指示种４９种，寡污水体指示种２１种。优势种为颗粒直链藻极狭变种（Ｍｅｌｏｓｉｒａｇｒａｎｕｌａｔａｖａｒ．ａｎｇｕｓｔｉｓｉｍａ），颗粒直链藻（Ｍ．ｇｒａｎｕｌａｔａ）和小颤藻（Ｏｓｃｉｌａｔｏｒｉａｔｅｎｕｉｓ）。浮游植物的细胞密度为８．５３×１０７／１，生物量为１６．３４ｍｇ／１，浮游植物群落结构的组成表明，青山水库已属富营养型水体，并有继续发展的趋势。A phytoplankton survey was carried out in Qingshan Reservoir of Zhejiang Province in Nov.1995 and April 1996.A total of 101 taxa belonging to 58 genera was been identified,including 39 taxa of Chlorophyta,24 taxa of Bacillariophyta,13 taxa of Cyanophyta,9 taxa of Euglenophyta,6 taxa of Pyrrophyta,5 taxa ecah of Cryptophyta and Chrysophyta.Among them,there were 5 polysaprobic indicator,24　ɑmesosaprobic indicator,49 βmesosaprobic indicator and 21 oligosaprobic indicator species.The dominant species were Melosira granulata var,angustissima,M.granulata and Oscillatoria tenuis.The average biomass of phytoplankton was 16.34 mg/1 and cell density was 8.53×107/1.According to the structure of the phytoplankton community,Qingshan Reservoir at present is an eutrophic water body,and the tendency to heavy eutrophication cannot be ignored.
