【摘要】 <正> 五台山海拔3058米,为华北第一高峰,位于山西省东北部的五台县、繁峙县境内,地理坐标北纬38°53′—39°6′,东经113°28′—113°40′。五台山在我国地质地貌研究上占据着重要地位。它是太古界五台群变质岩系的建群地点,也是著名的北台期夷平面的命名地。由于山体高度较大,自第四纪晚冰期以来,虽未遭受山岳冰川的作用,但古冰缘和现代冰缘现象皆十分发育。更多还原

【Abstract】 Wutai mountain located near Wutai county in Shanxi Province is the highest peak (3058) in the North China. Both ancient periglacial phenomena and present periglacial phenomena have been developed. Periglacial landforms are as follows: cryoplanation surface, tors, blockfield, block slopes, stone stripes, stone circles, stone nets, polygons, frost block, turfs, solifluction lobes, blockstreams, thaw hollow, dells, stone-banked terraces, stone banks, periglacial loess, etc.Both ancient periglacial phenomena and present periglacial phenomena have relation originally on Mt. Wutai. In the late Pleistocene, the mean annual temperature was about 3-4℃ lower than that at present on the top of Mt.Wutai, but it is about 10-11℃ lower than that at present on the surface of Shanxi Plateau.There was a periglacial age in the late glacial age of the Quaternary in the Wutai Shan area and it was called the Wutai Periglacial age, but now it goes into a sub-Periglacial age.更多还原
