| Abstract: | This paper deals briefly with the advantages of applying remote sensing images to the study of dunes and emphatically describes the image characteristics of various types of dunes in deserts. Formation mechanisms of some kinds of dunes are tentatively put forward according to their morphological features on the remote sensing images. Some problems are also discussed such as the significance of the remote sensing interpretation of dunes in line selection and the relationship between blown sand and line selection for railway and highway construction. |
