| 摘 要： | 本文利用250m分辨率的MODIS数据和准实时的地面采样数据,运用线性回归方法反演了太湖的悬浮物浓度,结果表明悬浮物浓度与第1波段相关性最好,PEARSON相关系数为0.31,在所有的波段组合中,其中以与波段M1+M2组合的相关性最好,呈典型正相关。并以此为基础建立了太湖的悬浮物浓度反演模型,这对于利用高时间分辨率的遥感源数据,研究太湖悬浮物浓度的时空变化规律具有重要意义。

| Abstract: | Based on the 250m bands of MODIS and near-real-time sampling data,Solid Suspended Matter Concentration(SSMC) are quantitatively retrieved using linear model.The result shows that the SSC of Taihu Lake has the highest correlation coefficient with MODIS band 1 and the lowest correlation coefficient with MODIS band 2;of all the 250m-band combinations,SSMC has the highest correlation coefficient with M1 M2,so the SSMC quantitative retrieval model was built through the correlation analysis.This plays an important role in the SSMC time-space distribution analysis using high time-resolution remote sensing data. |
