| 英文摘要 | The permafrost in the Da Xing'anling Mountains Northeastern China has experienced rapid and significant degradation due to climate warming and human activities during the last few decades. In this study, the permafrost degradation and freezing/thawing characteristics of the active layer at Mo'he airport were investigated through a ground temperatures data set collected over 10 years of measurements. During the monitoring period, thawing permafrost under the airport was observed, induced by climate warming, and thermal disturbance of airport construction and operation. The permafrost table under the blast pad declined considerably and varied from - 9 m to -14 m, and from - 4.5 m to -12 m under the natural site. The maximum depth of frost penetration at this airport shows a decreasing trend. The freezing duration of soil under the blast pad is shorter comparing with the natural ground surface, while its thawing duration is longer. The warming rates of permafrost at -10 m depth under the blast pad were 0.25-0.33 degrees C/a, and those under the natural ground were 0.03 degrees C/a and 0.15 degrees C/ a. The results provide valuable data for designing, construction and operation of the airport, and a reference for other airports construction in permafrost regions. |
