青山湖水体总悬浮物浓度的高光谱遥感反演
Retrieval of Total Suspended Sediment Concentration in Qingshan Lake by Hyperspectral Remote Sensing
摘要
Abstract
According to the measured hyperspectral remote sensing data and synchronous sampling data about the water quality of Qingshan Lake on November 9,2010, the inherent optical properties of the water were analyzed ,based on which the retrieval of total suspended sediment concentration (TSS) in Qingshan Lake was studied by three methods of single band, spectra ratio of two bands and reflectance first-derivative. As indicated by the results ,the three methods appeared to be significantly correlated with total suspended sediment concentration. The correlation coefficient R2 and RMSE of the first-derivative model at 688 nm were 0.932 8 and 2.896 1 mg/L respectively ,therefore it was the best model for the retrieval of TSS concentration in Qingshan Lake. The study provided basis for the retrieval of large-scale water by satellite remote sensing.关键词
