摘　　要：于2010年5-11月对潘家口水库浮游植物进行采样调查,分析了浮游植物的种类组成、优势种、细胞密度、多样性、均匀度等群落结构及时空变化特征。结果表明：潘家口水库共鉴定出浮游植物8门29种41属,其中绿藻门种类数最多,共21种,占浮游植物总种数的51.22%;其次是蓝藻门,共8种,占浮游植物总种数的19.51%。浮游植物的种类组成表现出明显的季节性和区域性变化,且以绿藻门占绝对优势,5-7月优势种为小环藻、针杆藻和衣藻,8-11月优势种为假鱼腥藻。浮游植物细胞密度4.74×106~8.24×107cells/L之间,8月份细胞密度最大,6月份最小。浮游植物多样性和均匀度较好,分别在0.01~1.97和0.01~0.94之间,浮游植物群落结构处于稳定状态。To understand ecological characteristics of phytoplankton community in Panjiakou Reservoir, an investigation was done from May to November 2010. Results showed that total 41 species, 29 genera and 8 phylum of phytoplankton were identified, and the largest species were green algae, which was 21 species, accounting for 51.22% of total phytoplankton species. Followed by blue algae, which was 8 species, accounting for 19.51% of total phytoplankton species. The species composition of phytoplankton showed significant seasonal and regional changes, and green algae was advantageous absolutely, with dominant species as Cyclotella, Chlamydomonas and Synedra from May to July, Pseudanabaena from August to November. Cell density of phytoplankton was 4.74×106-8.24×107 cells/L, with the maximum in August and the minimum in June. Diversity and evenness indices of phytoplankton were good, respectively in the range of 0.01-1.97 and 0. 01-0.94. The structure of phytoplankton community was relatively stable.
