Abstract
As the growth cycling of crops is usually shorter than the one of forest. The change of status of crop growth was pronounced and quickly with development stages. Therefore it is useful to know the change of the features of crop growth during growth cycling in hyperspectral remote sensing. The reflected spectra of canopies of five crops, early rice, later rice, summer maize, cotton and soybean were measured with SE590 spectrometer from June to September 1997, in Beijing. The features of first-order derivatives of canopy reflectances for each of the five crops are changed regularly with the phenological evolution. The possibilities of identification of crop types with the features of red edge are discussed.
