摘要:
2007年4月-2009年5月对安徽女山湖自然保护区浮游生物群落生态进行调查研究, 共检出浮游植物8门45属113种;浮游动物包括原生动物、轮虫、枝角类、桡足类, 共检出33属78种.分析表明女山湖不同季节浮游生物种类组成的变化趋势不同, 但整体看来, 浮游植物组成以蓝藻为主, 浮游动物以轮虫为主;浮游生物量在不同季节波动较大, 表现为夏季> 春季> 秋季> 冬季, 而不同年份同一季节的生物量变化不大.浮游生物的多样性指数在不同季节的变化较大, 而丰富度指数D在不同季节变化不大, 大多数在1.3-3.9之间, 均匀度指数J'在0.5-0.8之间.平均溶氧量PG达2.62mg/L.综合判定, 女山湖属于中富营养型, 浮游动物群落结构和组成相对稳定, 具有较大的开发利用潜力.

Abstract:
In order to understand the status of water quality of nature reserve area of the Lake Nüshan, the plankton community composition was investigated from April, 2007 to May, 2009.113 species, 45 genera and 8 phylum of phytoplankton were observed in the whole nature reserve area, and 78 species and 33 genera of zooplankton including the Protozoa, the Rotifer class, the Cladocera, the Copepoda were also observed. It indicated the plankton composition of diversity of the Lake Nüshan was difer-ent in different seasons. The blue green algae and rotifer were the dominant species in phytoplankton and zooplankton on the whole. Variation of the plankton biomass was big in the different seasons, which displaying the summer> spring> autumn> winter, but less variation of the biomass was found in the same season in different years. The diversity index of plankton changed greatly in the different season, but variation of the abundance index is not obvious in different season. The majority richness index D were 1.3-3.9, evenness index J' 0.5-0.8. The average dissolved oxygen was 2.62mgL. In summary, the Lake Nüshan belonged to the middle-eutrophic lake type, and the composition and structure of plankton community were relatively stable, and had good potential value of exploitation.
