Changes in the permafrost environment under dual impacts of climate change and human activities in the Hola basin, northern Da Xing'anling Mountains, Northeast China
Abstract The Hola basin in the northern Da Xing'anling Mountains in Northeast China has been extensively developed for coal mining since the 1980s, resulting in a significantly degrading permafrost environment. However, the changing thermal state of permafrost under the boreal forest remains un...

Abstract The Hola basin in the northern Da Xing'anling Mountains in Northeast China has been extensively developed for coal mining since the 1980s, resulting in a significantly degrading permafrost environment. However, the changing thermal state of permafrost under the boreal forest remains unclear. Based on ground temperature records from nine monitoring boreholes at three areas (disturbed, backfilled, and undisturbed areas) from 2015 to 2020, the thermal state of permafrost under the dual influences of climate change and human activities were evaluated. It is found that the temperatures at the depth of zero annual amplitude (T ZAA ) in the disturbed area increased by 0.2–0.5°C during the past 6 years, turning the cold permafrost (T ZAA ≤ −1.0°C) into a warm one (−1 ≤ T ZAA ≤ 0°C).

As the permafrost degrades, the boreal permafrost eco‐environment has changed dramatically, as revealed by the draining and drying up of the Yueya'hu Lake in the southern Hola basin.
