摘要: 神农架位于中国第二阶梯的东缘,属大巴山脉东南部的巫山山脉。在行政区划上属湖北省神农架林区,地靠川鄂边界。 从宏观上看,本区海拔1000—1200米的山原期剥夷面广泛分布,大体上由南向北缓倾。

Abstract: Shennongjia Mountain is located in the mountainous region of the western Hubei province at about 31°20’-31°30’N with its summit 3105.5 m high near which the rock sea occupying a large area above 2800 m is very conspicuous. We decide that the rock sea was formed in the Wurm. glacial period. In post glacial period, with the vertical zones shifting upwards, the ancient rock sea gradually became steady and was subject to reformation under present climate. Accordingly, we come to the general conclusion that the rock sea line is always 250-350 m lower than the snow line at any time and at any place, and glacier couldn’t be formed in the Late Wurm, because the rock sea was formed at its peak during that period. As a fact, traces of glacier in the Late Wurm in Shennongjia Mountain have not been found.
