Abstract

Soil erosion is one of the important environment problems，and land use classification is an important process in this aspect. The normal automatic classification (supervised classification and unsupervised classification) based on spectral characteristics cannot meet the accuracy needed. Therefore, the slope (produced by DEM) which affects the land use type location and the NDVI (produced by TM images) which reflects the vegetation coverage sensitivity should be taken into account. With Yanhe basin as the study area, the authors carried out the research on methods for extracting the land use information in complicated areas on the loess plateau. The result indicates that the division of the image into several parts according to the TM image characteristics and the extraction of the land use type one by one assisted by the slope are suitable for the complicated terrain area. The result obtained serves as an important reference to the remote sensing classification technical system.
