摘要	The continuum is improved with technical method of slope extremum, and assistance of computing programming, such as VC++. Extreme value points of spectral curve are obtained by the first derivation, and are used to get local spectral maxima by maximal or minimal slope. Thus, points on the continuum are quickly acquired. In this study, hyperspectral data of rock and vegetation are surveyed in Beiya Gold mine, Heqing county, Yunnan province, China. Correspondence analysis (COA) and cluster analysis (CLA) are used to process original hyperspectral data of these field objects, and their corresponding continuum-removed data, respectively. The differences in results of two kinds of data show that normalized spectrum curve enhances spectral absorption features greatly, and the effect of field factors is decreased obviously, leading to a better classification of objects. On the other hand, the spectral ranges are obtained to identify rocks and vegetations in the field, and provide a clue to hyperspectral image of objects.
