摘要:

为揭示鲁迅公园湖泊水体浮游植物的群落结构特征和水体健康状态, 于2019年1—10月对鲁迅公园湖泊水体进行了生态学调查, 分析了浮游植物的群落组成、密度、生物量、多样性、均匀度及优势种. 共鉴定出浮游植物8门83属, 其中蓝藻门、绿藻门和硅藻门物种数量最多, 全年平均细胞密度为14.17 × 106 ind/L, 全年平均生物量为3.57 mg/L, 平均细胞密度和生物量都随着季度变化而增加; 优势门类为蓝藻门、绿藻门和硅藻门, 主要代表属有伪鱼腥藻、平裂藻、栅藻、小环藻. 采用冗余分析对鲁迅公园湖泊水体中的环境因子与浮游植物之间的关系进行了进一步解析, 结果表明, pH值、硝态氮、亚硝氮和高锰酸盐指数是影响浮游植物群落结构的关键影响因子.

关键词: 浮游植物, 密度, 生物量, 环境因子

Abstract:

In this study, an ecological survey of the lake water in Luxun Park from January to October 2019 was conducted to determine the community structure characteristics and health of phytoplankton in the water. In particular, the community composition, density, biomass, diversity, uniformity, and dominant species of phytoplankton were analyzed. A total of 83 genera of 8 phyla of phytoplankton were identified; of these, Cyanophyta, Chlorophyta, and Diatoms had the largest number of species. The annual average cell density was 14.17×106 ind/L, and the annual average biomass was 3.57 mg/L. Density and biomass typically increase with seasonal changes. The dominant phyla were the Cyanophyta, Chlorophyta, and Diatom phylum; meanwhile, Pseudo-Anabaena, Platychophyta, Scenedesmus, and Cyclotella were the major dominant species. Redundant analysis was used to further analyze the environmental factors in the lake water of Luxun Park. The results showed that pH, nitrate nitrogen, nitrous nitrogen, and permanganate index are the key factors affecting the structure of the phytoplankton community.

Key words: phytoplankton, density, biomass, environmental factors
