摘要：Land desertification has become a significant issue of economy and ecological environment in global area. In this paper, we have applied the object-oriented method to the research of Zhenglanqi basin and the West of Badain Jaran Desert which present obviously different characters of china. On the basis of the multi-spectral images of Beijing-1 in June and September in 2006, under the standard classification system of desertification land, the object-oriented method is performed in the desertification land extraction from mid-resolution images, and the classification precision is evaluated in contrast to the traditional classification methods. Through the field investigation data and the panchromatic Beijing-1 data with 4 meters spatial resolution, the result shows the overall precision is appraised and can respectively reach 94% and 92%
