Abstract

Abstract

The Zhongba rift zone located on the west side of the southern Tibet rift system has well⁃developed faults and clear faulted landforms. However, the study on the activity of the fault is still lacking, which hinders our understanding of the deformation mechanism of the entire southern Tibet rift system. Based on GIS spatial analysis technology, we used the Digital Elevation Model data system to extract geomorphic parameters in this area, including topographic slope, topographic relief, channel steepness index, and knickpoints. We analyzed 36 basins on both sides of the Zhongba rift. The results show that the topographic slope is consistent with k_sn. On the west side of the Zhongba rift, tributaries located on the north and middle sections have steeper slopes and higher k_sn; tributaries in the south have steeper middle section with higher k_sn value. On the east side, the slope and k_sn are steep at the middle part and gentle at both ends. The river profiles display that the channel steepness are different on both sides of the knickpoints. The rivers of the east and west sides have the highest channel steepness near the outlets, and decrease towards the upstream. Generally, the river channels on the west sides are steeper than ones on the east side. Based on the analysis results of the topographical slope, river profiles, and knickpoints, we suspect that the tectonic activity of the faults on the west side of the Zhongba rift may be stronger than that on the east side.
