In the paper，the macroscopic features of sandy land and drainage network were carefully analyzed according to remotely sensed images and field investigations. It was found that there were five identifiable stages of drainage network，codes as paleochannel-I to -Ⅴ. The distribution characteristics of each drainage network stage were different from others. There were at least four activation stages of desert.
