补充资料:冈底斯山脉
冈底斯山脉 横贯中国西藏自治区西南部,与喜马拉雅山脉平行,呈西北-东南走向,属褶皱山。冈底斯藏语意为众山之主。东接念青唐古拉山脉。长1100千米。海拔约6000米。玛法木错以北的主峰冈仁波齐峰,海拔6656米。位于普兰县。最高峰为冷布岗日,海拔7095米。喇嘛教以冈底斯山为宇宙中心,尊为圣地。尼泊尔人、印度人则以此山为湿婆(Siva,印度教三尊神之一)的乐园。冈仁波齐峰和纳木那尼峰间的玛旁雍错为圣湖。香客多来此朝拜。由巴噶经普兰,沿孔雀河谷有道路通往尼泊尔。地势高耸,为内陆水系和印度洋水系的分水岭。印度河上源狮泉河发源于冈底斯山北侧,朗钦藏布(象泉河)发源于山南,进入印度境内称萨特累季河。冈底斯山南北两侧均为地震活动带,曾多次发生过6级以上地震。
