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M_1＋M_2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。 |

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 coeflqcient with MODIS band 1 and the lowest correlation coefficient with MODIS band 2 ; of all the 250m-band combinations, SSMC has the highest correlation coeflqcient with M_1 ＋ M_2, so the SSMC quantitative retrieval model was built through the correlation analysis. This plays an important role in the SSMC timespace distribution analysis using high time-resolution remote sensing data. |
