| Abstract: | By use of Landset TM image of Nanchong in August 2000, used the method named supervised classification to carry on the investigation of land utilization。 An improved method which extracts factor from the features sub- regionally is used. The method can easily interpret such as construction sites and bare land which are not easily to interpret, and effectively reduce the impact of mixed conifer, thus improve the accuracy of land-use information. |
