| 太湖水环境质量在最近的十年中下降 1-2个等级.1990年 86.5%的水体为Ⅱ、Ⅲ类,到 2000年太湖水体 87%为Ⅳ类;1990年太湖水体为中-富营养化,2000年太湖水体以富营养化为主.本文通过分析经济社会发展和水环境变化,认为太湖流域工业化与城市化及居民生活水平的提高,以及不合理的农业生产方式,使水环境面临巨大的压力,环保意识落后、治理能力不足、管理体制不合理是太湖目前水环境恶化的根本原因. |

| Abstract: |
| The water quality of Taihu Lake has been declined for 1-2 level in the past decade.In 1990, 86.5 percent of lake water belonged to Surface Water Level 2-3 (GB3838-88)and was from mesotrophic to eutrophic, while 87 percent of them belonged to Surface Water Level 4 (GB3838-88)and under heavy eutrophication in 2000.Through analysis of the social-economic development and water environment change in the watershed, the author suggests that industrialization, urbanization as well as shifts of irrational agricultural production style and life quality improvements contributed greatly to water quality deterioration of Taihu Lake.Moreover, irrational management system, and the lack of environmental protection idea and capacity of sewage treatment are the fundamental reasons for water environmental deteioration in Taihu Lake. |
