【摘要】 中天山研究区内石冰川有数百条之多,在86°E以西地区以阿尔卑斯型为主,东部则以科罗拉多型为主。前者具有规模大、活动性强的特点,后者正相反。东部叶状石冰川在结构上分为三层,具有“一冻到底”的特点。作者认为本区石冰川东西间分布差异主要是因西部更冷湿所致,地形、岩性、冰川和灾害地貌过程等因素促进了这种差异的形成。更多还原

【Abstract】 There are several hundred rock glaciers in the studied Central Tian Shan Mts area. In the west of longitude 86 E, there are mainly Alps type rock glaciers with large scales and str-ong activities. In the area east of the line, there are Colorado type rock glaciers with small scales and weak activities. The eastern lobate rock glaciers which are "frozen throughout bot-tem" can be divided into three layers in structure. The authors consider that the cold and hu-mid conditions in the west region are the main reason to create the distributive difference of rockglacies betwwen the east and west. The factors of topography, lithology, glacier and geomorphological processes also affect the fot.nation of the difference.更多还原
