摘　　要：美曲藏布位于日喀则地区,地处西藏中南部,冈底斯山南麓,规划河段内拟新规划3座水电站,均为坝式开发。区内地质构造复杂,大地构造上位于印度陆块与冈底斯—拉萨陆块结合部,通过对该区所处的区域构造背景分析,对其区域构造稳定性进行了初步评价。Meiqu River, located at south side of the Gangdise Mountain, belongs to Shigatse Region, middle- southern area of Tibet. It is planned that three dam-type hydropower stations are built in Meiqu River catchment. The planning zone is situated at the combining zone of India plate and Gangdese-Lhasa plate, resulting in the complicated geological conditions. The regional tectonic stability is evaluated through the analysis on regional tectonic background, the charac- teristics of faults and seismic activities there.
