Abstract

Abstract

There are strong, fresh tectonic processes and a series of active faults in the northern part of East Kunlun in Tibetan plateau, controlling the geomorphology and the water system of this area. Most of the active faults have been confirmed, while some are only presumed qualitatively at present. This paper introduces two kinds of geological factors, the Stream Length-gradient index (SL index) and Hack profile, which can effectively reflect regional tectonics, and particularly describes and studies the gradient change of the longitudinal profile of the Kunlun river and the contrast of river terraces in space in Kunlun area. It shows that there exists a corresponding relationship between Hack profile and SL index of the Kunlun river in shape and the mutation of the SL index is mainly controlled by the action of fault. We have also proved the activity of the Kunlunhe-Yeniugou fault and the central fault of east Kunlun from Quaternary, and believe that strong differentia uplift controls the geomorphologic evolution and river development of east Kunlun and will exert far-reaching influence on them.
