摘要
2008年12月对赣江中游进行了浮游生物的调查。鉴定结果如下：浮游植物共8门30属47种，硅藻门30种，绿藻门10种，蓝藻门1种，金藻门2种，裸藻门1种，甲藻门1种，黄藻门1种，隐藻门1种。浮游动物27种，其中轮虫类11种，枝角类8种，桡足类6种，原生动物2种。进行了浮游生物多样性指数Margalef的测定，各点Margalef指数在1．42—3．30之间，平均值为2．31，结果显示赣江中游水体属于中或轻度污染，且不同采样点间污染程度存在明显差异。
It investigated the planktons in the middle reaches of Ganjiang River in December 2008. The result is as follows ：47 species of phytoplankton were identified,which belongs to 30 genera of 8 phyla,among which there were Bacillariophyta 30 species, Chlorophyta 10 species, Cyanophyta 1 species, Chrysophyta 2 species, Euglenophyta 1 species, Pyrrophyta 1 species, Xanthophyta 1 species and Cryptophyta 1 species. 27 species of zooplankton were identified, among which there were Rotifera 11 species, Cladoeera 8 species, Copepoda 6 species and Protozoa 2 species. The margalef index were analyzed.
