摘要
根据2001～2002年对筼笃湖所采集样品的分析,对浮游植物的种类组成、优势种组成和细胞数量等的空间分布和季节变化进行分析研究.结果表明,筼筜湖浮游植物共出现91种,优势种为中肋骨条藻(Skeletonema costatum)和裸藻(Euglena),浮游植物具有种类数少,细胞数量高,丰富度、多样性指数和均匀度都较低,优势度高的特点,表明筼筜湖水体受污染的程度较为严重.
Based on the results of survey on phytoplankton in Yundang Lagoon from 2001 to 2002, the spatial distribution and seasonal variation of the species composition, dominant species and cells abundance of phytoplankton were discussed. The results show that 91 species were identified, the dominant species were Skeletonema costatum and Euglena, the number of phytoplankton species in Yundang Lagoon was less, and the cells abundance of phytoplankton was high, the abundance （d） , diversity （H＇） and evenness （J） were low, and dominance （D2） was high. It shows that the pollution of water in Yundang lagoon was severe.
