%X We take the Water Quality of Weihe River in Shaanxi Province as our research object.The monitoring data in situ and the SPOT-5 remote sensing image data in the corresponding time are obtained.We correct the SPOT-5 remote sensing image by seven atmospheric correction methods such as dark-object methods (DOS),radiative transfer models etc.With the corrected remote sensing data,we retrieve some water quality parameters by means of multiple linear regression,support vector machine (SVM) and BP neural network.The results show that it is feasible to retrieve water quality of Weihe River through remote sensing data,the atmospheric correction can improve the accuracy of the retrieving to a certain extent.The method of eliminating the dark-object each band after radiometric calibration for remote sensing images is a better method for SPOT-5 remote sensing image.
