“…However, T ZAA presented the opposite trend for the undisturbed sites in this study. Previous studies show that it generally takes about 10 years for the rising of air temperature to reach the depths of 25-40 m in permafrost (Goto & Yamano, 2010;Zhang et al, 2020). With the meteorological data from Mo 0 he and Beijicun Changing trends of ground temperature were identical for GL-9…”

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 (TZAA) in the disturbed area increased by 0.2–0.5°C during the past 6 years, turning the cold permafrost (TZAA ≤ −1.0°C) into a warm one (−1 ≤ TZAA ≤ 0°C). Additionally, the permafrost table was lowered by 0.8–7.0 m. As a result, subaerial supra‐permafrost talik occurred. However, TZAA in the undisturbed areas lowered by 0.03–0.11°C, possibly due to the lagged response of the local climate cooling during 2001–2010. In the meantime, TZAA rose sharply in the disturbed areas, indicating more significant influences of intense human activities on permafrost in comparison with that of climate change. 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. These results help reveal the physical mechanisms, evaluate the rates and amplitudes of environmental changes, and manage the boreal forest environment and resources in a sustainable manner.

“…Measurements of borehole temperature depth profile (BTDP) evidently show that there are temperature deviations from the linear steady-state ground temperature in the upper sections of boreholes (Goto, 2010, Harris and Chapman, 1997, Lachenbruch and Marshall, 1986, Guillou-Frottier et al, 1998. Mathematical models have been used to simulate the change in ground temperature due to GW.…”

“…It is necessary to apply techniques to evaluate the vertical groundwater flux, including both recharge to and discharge from aquifers, to exploit and manage this invaluable resource appropriately. Since pioneering research in the 1960s (Bredehoeft & Papaopulos, ; Stallman, , ; Suzuki, ), heat has been recognized as a powerful tracer to quantify the interchange between surface water and groundwater (Irvine et al, ; Lu, Chen, Zhang, Su, & Chen, ; Naranjo & Turcotte, ; Rau, Andersen, McCallum, Roshan, & Acworth, ), reconstruct the history of surface temperature (Correia & Šafanda, ; Goto & Yamano, ; Huang, Pollack, & Shen, ), and estimate vertical groundwater fluxes based on subsurface temperature–depth (TD) profiles (Bense & Kurylyk, ; Irvine et al, 2017; Kurylyk & Irvine, ). As an indicator that can be measured easily and rapidly, using underground temperature to estimate groundwater flux is convenient, environmentally friendly, and inexpensive compared with other methods such as hydraulic modelling, chloride mass balance, and isotope analysis.…”

We developed a numerical model, RFLUX, which uses the heat tracer method for vertical groundwater flux estimation, and applied it to the Leizhou Peninsula, South China, to provide information to inform local groundwater resource utilization and management. The temperature-depth (TD) profiles of 24 boreholes, along with the observed ground surface temperature (GST) and surface air temperature (SAT) series in recent decades, were collected in this area. Underground TD data demonstrated the capacity to identify groundwater flow patterns, and local GST and SAT data demonstrated a strong correlation with each other over monthly, seasonal, and annual scales. In the RFLUX model, the average GST and SAT series were applied as an upper boundary condition, and a nonlinear initial condition was set using an analytical solution from the literature. The model results of selected TD profiles demonstrated that the annual vertical groundwater flux was about 0.15 m a −1 , which tended to be overestimated if a linear initial condition was used. This model can be easily applied with minor modifications, considering its clear purpose and simplicity.
