| 摘 要： | 以太湖为研究对象,对TM各波段辐射率与水质参数进行拟合,分析了TM各波段经6S模型大气校正和未经校正直接拟合在监测内陆湖泊水质中的可行性。结果表明:TM波段经6S模型校正后能与太湖水质参教进行较好的匹配,同时通过实验得到了太湖地区水质参数的实用性回归公式。

| Abstract: | Lake Taihu as one of the largest freshwater lakes, its water quality influences many people's lives. This paper attempts to study the relationship between TM bands and the water quality parameters, especially the atmospheric corrected TM bands by the 6S model. Stepwise multivariate regression is used to establish the more accurate regression formula. Results indicated that the corrected band data have a higher correlation accuracy with the water parameters. Also this paper derives the applicable regression formula to better assess the water quality parameters. |
