摘  要：
自2011年1月、4-12月逐月对上海市水源地——青草沙水库的浮游植物群落结构进行调查和分析。本研究共检出浮游植物8门99属223种,细胞丰度变化范围为86.37×104~2 594.63×104cell/L,全年优势种为小环藻、卷曲鱼腥藻、微小色球藻、针晶蓝纤维藻、球衣藻、啮蚀隐藻,偶有咸水和半咸水种检出。蓝藻密度在全年占据优势,优势类群季节演替明显,表现为:春季为色球藻属、蓝纤维藻属,夏季为微囊藻属,秋季为卷曲鱼腥藻、鞘丝藻属。典范对应分析(CCA)结果表明浮游植物群落结构与水温、悬浮物含量和浮游动物的牧食作用相关。

摘  要：
Phytoplankton abundance and community structure were investigated and analyzed from January,April to December 2011 in Qingcaosha Reservoir,an important water source in Shanghai,China. Total 8phyla,99 genera,223 taxa of phytoplankton were identified. The phytoplankton abundance ranged from86. 37 × 104- 2594. 63 × 104 cell/L. Cyclotella sp., Anabaena circinalis, Chroococcus minutus,Dactylococcopsis rhaphidioides,Chlamydomonas globosa and Cryptomonas erosa dominated throughout the year. Some species in salt and brackish water appeared occasionally. Cyanobacteria abundance dominated throughout the year,and dominant genera succeed from Chroococcus spp. and Dactylococcopsis spp. in spring,Microcystis spp. in summer,to Anabaena circinalis and Lyngbya spp. in autumn. Canonical Correspondence Analysis( CCA) indicated that water temperature,suspended solid and grazing effect of zooplankton could be the main factors shaping the phytoplankton community in the Qingcaosha Reservoir.
