Hyperspectral remote sensing technology is widely used to detect element contents because of its multiple bands,high resolution,and abundant *** researchers have paid considerable attention to selecting the optimal bandwidth for the hyperspectral inversion of metal element contents in rocks,the influence of bandwidth on the inversion accuracy are *** this study,we collected 258 rock samples in and near the kalatage polymetallic ore concentration area in the southwestern part of Hami City,Xinjiang Uygur Autonomous Region,China and measured the ground spectra of these *** original spectra were resampled with different bandwidths.A Partial Least Squares Regression(PLSR)model was used to invert Cu contents of rock samples and then the influence of different bandwidths on Cu content inversion accuracy was *** to the results,the PLSR model obtains the highest Cu content inversion accuracy at a bandwidth of 35 nm,with the model determination coefficient(R^(2))of *** PLSR inversion accuracy is relatively unaffected by the bandwidth within 5-80 nm,but the accuracy decreases significantly at 85 nm bandwidth(R^(2)=0.5473),and the accuracy gradually decreased at bandwidths beyond 85 ***,bandwidth has a certain impact on the inversion accuracy of Cu content in rocks using the PLSR *** study provides an indicator argument and theoretical basis for the future design of hyperspectral sensors for rock geochemistry.
