Study on Hyperspectral Reflectance of Ramie Leaf in Different Genotypes
摘要
Abstract
The hyperspectral data of 27 ramie leaves with various genotypes under field-grown were collected and statistically analyzed.Research results showed that the hyperspectral curve of these ramie leaves demonstrated typical spectral characteristics of green plants,and its green peak value and red valley value were 553 nm and 668.9 nm respectively.The most centralized locations of central wavelength were at the fourth peak and the fourth valley,while the locations of central wavelength at the first peak and red valley were relatively decentralized.The most obvious differences in reflectivity occurred at the the green peak,fourth valley and the red valley,in contrast,the reflectivity differences at the second peak,first peak and the first valley were unobvious.As for the parameters of three edges,the greatest differences in location and amplitude were at the red edge and the blue edge and the blue edge respectively.In addition,there were greater differences in the vegetation index calculated with the green peak or the red valley as the sensitive waveband.关键词
