| 中文摘要: |
| 于2018年—2019年在鄱阳湖区周边选取4个县（区）10个村庄的典型门塘开展浮游藻类采样调查。研究共鉴定出藻类6门83种，以蓝藻门、绿藻门和硅藻门为主；浮游藻类细胞密度全年范围为7.30×104个/L～2.78×1011个/L，年均值为1.4×1010个/L，其中夏季细胞密度最大，冬季细胞密度最小；优势种主要有小环藻、微囊藻、铜绿微囊藻、卵形隐藻等，且具有较为明显的季节演替，全年优势种为小环藻；藻类多样性指数（H′）年均值为1.49，丰富度指数（M）年均值为1.92，全年水体生物学评价结果为中度污染。 |

| A survey was conducted on phytoplankton in 10 typical rural ponds in 4 districts around PoYang Lake area from 2018 to 2019. The identified phytoplankton belong to 6 phyla 83 genera. Cyanophyta， Chlorophyta， Bacillariophyta were dominated. The cell density〖JP3〗 of phytoplankton ranged from 7.30×104 ind/L to 2.78×〖JP〗1011 ind/L yearly， the annual average was 1.4×1010 ind/L， the maximum cell density appeared in summer and the minimum in winter. Cyclotella， Microcystis， Microcystic aeruginosa， Cryptomonas cvata were dominant species which had pronounced seasonal succession， and Cyclotella was annual dominant species. The average Shannon Weiner diversity index was 1.49. The Margalef abundance index was 1.92. The water was moderately polluted by biological evaluation. |
