Based on the field survey for the alpine zone of Taibai Peak of Qinling Mountain( Taibai Mountain),it was confirmed that above the altitude of 3000 m,there are the typical periglacial geomorphology such as stone field,stone river and rock stream,block glacier and underground river,talus and periglacial tor,fort- shaped rocks,nivation hollow and stone- circles. The periglacial loess was firstly found. The fabrics of the periglacial gravels revealed that gravels are nonuniform in size and chaotic mélange. AB loft beyond block glacier is much greater than slope gradient,which shows the accumulation is unstable. The analysis of the control factors and rock fabric indicated that due to the differences of the landforms,lithology,slope and mountain height,it resulted in a significant diversity of periglacial geomorphology on distribution,types,landscape features and fabric characteristics,reflecting an unique environment of Qinling Mountain. It means the mountain disasters happen easily. So the reasonable prevention measures should be planed.
