藏东地区地处横断山脉,平均海拔3500m以上。长期以来,很多小水电站不能正常运行、提前报废的问题十分突出。藏东小水电“短寿”的主要原因是:①站址选择不理想:首先,横断山脉西部三江弧形构造南段区域的地质条件十分复杂,地质灾害频率高,水土流失严重,选择理想站址很困难;其次,

The eastern Tibet is located in the Hengduan Mountains, with an average altitude of over 3500m. For a long time, many small hydropower stations can not operate normally and the problem of early retirement is outstanding. The main reasons for the “short life” of Tibet’s small hydropower are as follows: Firstly, the geological conditions in the southern section of the Sanjiang arc structure in the western part of the Hengduan Mountains are very complicated. The frequency of geological disasters is high and soil erosion is serious. Select the ideal station Site is very difficult; Second,
