1. Crushed rock layers are distributed widely in periglacial environment.

2. Many periglacial phenomena and paleobotany evidinces of environmental changes were retained in the Daqingshan area of northern China.

3. And, in the maritime Antarctica, various modern periglacial processes play an important role in weathering, material transportation and soil formation. Besides, chemical weathering processes, incl...

4. There are more than 60 kinds periglacial landforms all over the world.

5. Thus the extra-tropical zone of former pronounced valley formation was dominated by relict landscape features both glacial and periglacial.

6. At this time also the surrounding country was exposed to periglacial activity.

7. These have been gouged out of the hills, probably under periglacial conditions, and their debris spread on the lowlands below.

8. Wedge-shaped structure which is isolated from massive diamictite may be filled with the decay of an ice wedge in periglacial environment.

9. The content of heavy metal element of 16 species periglacial plant in Qinghai Daban mountain area was analyzed.

10. Such processes may include impact cratering, volcanism, glacial and periglacial geomorphology.

11. Frost action is one of the important environmental factors in alpine and periglacial climate. Among them, freeze-thaw process is the most influential geomorphologic process in the area.

12. Geomorphologic processes are very sensitive to climate changes in the boundary area between the fluvial zone and the periglacial zone.

13. The correlate analysis shows that heavy metal element accumulation in periglacial plants is influenced by the heavy metal element content in soil.

14. A number of these changes represented adaptations to grazing in Siberia's periglacial conditions.

15. This paper deals with the comprehensive division of the global periglacial geomorphology for showing the significance on the entire features of the global periglacial processes and their environment.
