Abstract Based on the RS and GIS technology, the authors mapped the remote sensing images of Qinghai-Tibet Plateau, interpreted and studied the water system of Gangdise block and, in combination with the fault interpretation of Gangdise area, analyzed the distribution characteristics of the water system in the study area. The results show that the water system pattern is controlled by active tectonics. The authors hold that the uplift belt and the rift zone in the Gangdise block has been uplifted discrepantly, along with the whole uplift of the Qinghai-Tibet Plateau since the Neogene. There exist many different kinds of nearly NS-trending fault structures along with the intense uplift of the plateau. In addition, the distribution and shapes of water systems and string-shaped lakes in Gangdise hinterland are controlled by the fierce neotectonic movement.
