Abstract: The threshold of NDVI classificat ion is one of the most popu lar m eth ods in th e classification of
remote sensing mi age. How ever, based on spectrum characteristics of ob jects, it cannot correctly identify
objects with the sam e spectrum characteristics and therefore cannot reach the requ ired accuracy. In th is paper,
w e take an area of th e upp er part of X it iaox i R iver in Anj i County as an exam p le and discuss the m ethod of
comb in ing texture of h igh2resolut ion mi ages w ith spectrum to mi prove th e accuracy of extracted in form at ion of
SPOT5 mi age. F ir st ly, prin ci
