    Vegetation structure and soil organic carbon storage across northern forest-tundra ecotones in continuous permafrost by H. Travers-Smith, N.C. Coops, T.C. Lantz, M. Hamp, D. Ignace, M.A. Wulder, J. van der Sluijs

    Published 2025-01-01
    “…In this study, we linked measurements of SOC with terrain and vegetation structure derived from drone imagery across treelines underlain by continuous permafrost in the Northwest Territories, Canada. We classified sites into three treeline types representing differences in vegetation productivity and topography. …”

    Study of the Characteristics Mechanical Damage and Constitutive Model of Crushed-Rocks from High-Grade Highway in Permafrost Region by Qinshuai Zhang, Qingzhi Wang, Jianhong Fang, Xiangqing Zhao, Jizhen Li, Shuan Li

    Published 2022-01-01
    “…Three types of rocks are selected to conduct uniaxial compression and microscope experimental to study the influences of freeze-thaw cycles on crushed-rocks from Gonghe-Yushu high-graded highway, which is the first high-grade highway built in permafrost regions in China. Using the hypothesis of Lemaitre’s strain equivalence principle and a theoretical model of crushed-rock deterioration after freeze-thaw cycles was established and verified by the experimental data. …”

    Study on the Effect of Unilateral Sand Deposition on the Spatial Distribution and Temporal Evolution Pattern of Temperature beneath the Embankment by Ling Chen, Hong Yu, Xiaolin Li, Zekun Ding

    Published 2021-01-01
    “…In the context of climate warming and the frequent wind-sand hazards in the Qinghai-Tibet Engineering Corridor (QTEC), the construction of the embankment will affect the thermal regime of permafrost underground. The influence of embankment construction on the variation of the permafrost table beneath it is different, especially for the regime with different mean annual ground temperatures (MAGTs). …”
