Suspended matter concentration is an important parameter of water quality and water environment evaluation.The field experiments including water quality analysis and spectrum measurements were carried out in 74 stations of Lake Tai during 14 days from 8th Nov.2007 to 21th Nov.2007.After analyzing the correlations between remote sensing reflectance and suspended matter concentrations,the results show that remote sensing reflectance in the range of 400~900nm wave bands is highly and moderately related to tota...
