摘　　要：根据2004年5、8月2个航次杭州湾生态监控区浮游植物的监测资料,对浮游植物的种类组成和多样性进行了研究。结果表明,2个航次共鉴定到浮游植物43种,隶属于4个门21属,以硅藻门为主,有17属36种;绿藻门1属2种;甲藻门2属2种;蓝藻门1属1种。浮游植物的细胞密度在3.7×103～6.7×105个/m3,平均为1.4×105个/m3。8月的细胞数量明显大于5月。多样性指数在1.06～2.91;8月略高于5月。5、8月杭州湾浮游植物的多样性阈值平均为1.6、1.8,属同一类型(Ⅲ),即说明5月和8月浮游植物季节差异不大,多样性较好。Base on the data obtained from the two cruises out in May and Auguest of 2004, the species composition and diversity level were analyzed. The results showed that totally 43 species of phytoplankton were identified, the biomass of phytoplankton ranged from 3.7×10^3 to 6.7×10^5 ind/m^3, and the average was 1.4×10^5 ind/m^3. The biodiversity index varied from 1.06 to 2.91, the average of diversity threshold on May and Auguest were 1.6 and 1.8, which showed that phytoplankton in Hangzhou Bay was better in diversity.
