摘要
目前,太湖水体受到了不同程度的污染。本文基于Landsat ETM+数据,结合SP水质等级评价模型对太湖进行水质等级监测,SP模型通过MATLAB编程实现。结果表明:整个太湖约77%处于中营养化水平,17%处于富营养化水平,仅5%处于贫营养化水平,如东太湖。
At present, Lake Taihu has been contaminated seriously resulted from the rapid economic growth. In this study, SP model was applied to monitor the water quality of Lake Taihu based on Landsat ETM＋ data, The SP model was carried out by MATLAB programming. The results show that about 77% of the Taihu Lake are nutrition, 17% eutrophic, only 5% oligotrophic, such as the East Taihu Lake.
