摘要: 研究了滩涂养鱼生态系统中藻类的种群结构等,结果表明:共有7门127种,年平均143.92×106个/L、平均生物量105.60mg/L;藻类种群结构、数量、生物量等存在动态变化;结构上以蓝、绿、硅藻门为主,裸、隐、黄、甲藻门为次要门类,绿藻门的种数最多并且占绝对优势;春季绿、硅藻门的数量和生物量大于蓝藻门,夏季蓝藻门藻数远多于其他藻类,秋季蓝、绿、硅藻门生物量接近;藻类组成与异龙湖接近、生物量较其小,但远超过洞庭湖区高产塘的生物量上限.Abstract: The population and biomass of algae were studied in embanked fish pond ecosystem along the coastal area of Jiangsu province. Seven phylum and 127 species of algae were found in the fish-pond. The average amount and biomass of algae were 143.92?06units/L and 105.6 mg/L during 7 months(from April to October). The change in composition, amount and biomass of algae was dynamic. Cyanophyta, Chlorophyta and Bacillariophyta were dominant phylum of algae in the ecosystem. The quantity and biomass of Chlorophyta and Bacillariophyta were larger than those of Cynaophyta in Spring, but smaller in Summer. The average biomass of three dominant phylum was similar in Autumn. The ecosystem of embanked fish pond in the coast area could therefore be classified into medium production level. The high salt content and low fertility in the coastal saline soil were overcome in the ecosystem. It is shown coastal land resources could be fully used for aquaculture to achieve production level similar to those obtained from high fertility soil.
