How to efficiently use hyperspectral remote sensing data to quantitatively retrieve bio-physical and bio-chemical crop parameters and accurately obtain regional crop growth information has always been one of the hot issues in agricultural quantitative remote sensing researches. Based on optimal selection of sensitive hyperspectral bands, the research on retrieval of winter wheat above-ground dry biomass(ADBM) from Hyperion hyperspectral imagery was carried out in Shenzhou County,Hebei Province of Huang-Huai...
