Impacts of Grassland Vegetation Cover on the Active-Layer Thermal Regime, Northeast Qinghai-Tibet Plateau, China
The impact of vegetation cover on the active-layer thermal regime was examined in an alpine meadow located in the permafrost region of Qinghai-Tibet over a three-year period. A high vegetation cover (93%) delayed thawing and freezing at a given depth relative to sites with lower covers (65%, 30% and...
