| 摘要: |
| 根据1987-1988年太湖实测水质数据,利用系统动态聚类分析方法,将17个指标按营养盐、有机质、有毒有害物质三种污染类型进行综合评估,获得了太湖水域各类污染指标空间分布态势及差异特点,揭示了太湖现存的三种污染模式及地域分布状况,为进一步治理和改善太湖水质提供依据。 |

| Abstract: |
| According to the date of water quality collected from Taihu Lake in 1987-1988,seventeen indexes in three pollution types of organic matter,hygienic index,nutrients,toxic and harmful materials were evaluated by means of a systematic dynamic cluster analysis.The spatial distribution of pollution index in Taihu Lake and the differences of index character were obtained,and the results revealed three type pollution models and their distribution status.This paper offers an important information for further improving water quality and controlling water pollution of Taihu Lake. |
