太湖悬浮物浓度的MODIS影像估测研究

Studying on Remote Estimation of Total Suspended Solids in Taihu Lake Using MODIS Imagery

摘要: 通过研究,发现在大样本(N=335)的情况下MODIS 500 mB1-B3与太湖悬浮物浓度具有较好的线性关系(R2=0.659)。同时,运用实测光谱深入分析悬浮物的敏感波段,进一步揭示了采用B1-B3估测的理论依据,并建立了适用于各个季节的太湖悬浮物通用遥感估测模型。

Abstract: Based on a large typically representative survey data(N=335) in Taihu Lake,a significant linear relationship was established between analytically measured total suspended solids(TSS) and MODIS B1-B3 at a resolution of 500 m.However,this paper also demonstrates why MODIS B1-B3 is applied by exploring how to identify the sensitive bands for detecting TSS.Finally,a general and robust regression model was developed to estimate TSS in Taihu Lake.
