| Abstract: | By using TM images in 1990,2000 and 2007 covering Qingling Mountains,spatial data about LUCC was obtained with the combination of visual interpretation and the decision tree classification.Then LUCC was analyzed through the matrix of the transfer of land-use change based on GIS technique and the statistical model.The results showed that,forest and grass was widely distributed in Qinling Mountains;except the increase of built-up land,other types reduced a little in the fore period.At the later state,the phen... |
