The Yarlung Zangbo River is the longest plateau river in China, with huge potential hydraulic energy. In order to make better use of hydraulic resources, we conduct research on the siting of hydropower stations.We analyze this issue based on the obtained geoscience and spatial information. For the problem, we extracted 999 sampling points on the main stream of the Yarlung Tsangpo River using ArcGIS, selected 50 of them. We have extracted key indicators for establishing hydropower stations based on various research reports, including economic cost, river width, geological foundation, drop, etc and used the Topos method to find the coordinates of the most suitable point for establishing a hydropower station, longitude 85.1312544645258 and latitude 29.3017619417134, and have marked them on the map.
