摘要：The composition and seasonal variations of phytoplankton of Lake Ladik were studied between June 2000 and May 2001. The taxa identified included members of Cyanoprokaryota (8), Bacillariophyta (46), Chlorophyta (54), Euglenophyta (30), Cryptophyta (2), Dinophyta (1) and Xanthophyta (1). In the phytoplankton, Cyclotella ocellata, Aulacoseria distans, Trachelomonas hispida, T. volvocina var. punctata, Cryptomonas ovata, Pediastrum spp., and Scenedesmus spp. were common organisms. Seasonal variations in phytoplankton appeared to be related to availability of light and temperature rather than various measured nutrients.
