Abstract :
Alxa Plateau is located in Central-north of China with average altitude of 1000 m a.s.l.. The Gobi desert and relict mountains characterizes the area. There are also many playas in the plateau. This is one of the driest area both in China and in the world. Based on radar penetration, through the analysis to SIR-A, SIR-B, SIR-C, Radarsat ScanSAR images obtained on different dates and several times field investigation, some subsurface old river valleys and buried lake basins were recognized, thus an old drainage composed with rivers and lakes can be delineated. Through this research, the preliminary drainage evolution process of this 300,000 km2 area since Tertiary period is established
