| 中文摘要: |
| 对苏州阳澄湖2009年—2011年的浮游藻类现状进行调查，采用硅藻指数和Shannon-wiener指数两种生物学指数评价阳澄湖水体污染状况。结果表明，在阳澄湖发现浮游藻类219种（包括变种），秋季的浮游藻类种类数多于春季；阳澄湖水质尚好，东湖南富营养化程度较为严重。目前阳澄湖的有机污染处于缓慢上升的态势，富营养化水平也不断提高。 |
| 英文摘要: |
| Research on phytoplankton status were carrying out from 2009—2011 in Yangcheng Lake, Suzhou City. Biological evaluation methods such as Bacillariophyta Index and Shannon-wiener Index were used to evaluate the water pollution state. The results show that there were 219 species(including varieties) of phytoplankton in this lake. Phyroplankton's species in autumn was more than that in spring; The water quality in Yangcheng Lake was still good and the eutrophication level was most serious in the East-South Lake. The organic pollutants were getting serious andante during these years in Yangcheng Lake, and also is the eutrophication level. |
