Sensitivity Analysis of Canopy Spectral Reflectivity to Canopy Structure Parameters
The sensitive parameters in the 4-Scale model are analyzed to study the influence of canopy structure parameters on the reflectivity of forest canopy.The sensitivity analysis of 26 model input parameters of the 4-Scale model is carried out by extended Fourier amplitude detection method,and the influence of these six parameters on the canopy reflectivity in the infrared and near-infrared bands is studied respectively,which provides a reference for the setting of input parameters in the 4-Scale model.
