| 英文摘要 | Rates of permafrost degradation at both the permafrost table and the base of permafrost were simulated using a prescribed rate of increase in mean annual air temperatures of 0.04 degrees C/a for a site in continuous permafrost near Changshitou. Mountain, eastern Tibetan Plateau. The results indicate that over 110 years, the permafrost table descends from a depth of 1.20 m to 1.48 m, and that the base of permafrost rises from the initial value of 55.0 m to 15.2 m. The predicted rate of basal permafrost degradation in low moisture content bedrock reaches a peak of 0.58 m/a after 60 years, assuming a constant thermal gradient at the base of 0.018 degrees C/m. The permafrost is persistent due to the ice-rich nature of the near-surface soil layers. Copyright (C) 2008 John Wiley & Sons, Ltd. |
