| 摘要: |
| 阳澄湖是太湖平原上第三大淡水湖泊和苏州市重要的综合水源。从2004年3-10月对阳澄湖进行了3次浮游植物的调查，共发现浮游植物8门83属211种（包括变种），其中阳澄西湖71属153种、阳澄中湖68属140种、阳澄东湖74属151种。并利用浮游植物的生物学多样性指数对阳澄湖进行了水质评价，该水体整体处于重污染状态，且污染呈西高东低分布。 |

| Abstract: |
| Yangcheng Lake is the third biggest fresh water in Taihu plain and the important water source in Suzhou. The phytoplankton investigation was carried out three times in Yangcheng Lake from March to October in 2004. 211 species of 83 genera of 8 phyla of phytoplankton had been identified, with 153 species of 71 genera in the west lake, 140 species of 68 genera in the central lake, and 151 species of 74 genera in the east lake. The water quality was assessed by the biological diversity index of phytoplankton. The water quality in Yangcheng Lake was regarded as severe pollution and pollution in the west lake was even more serious than in the east lake. |
