Soil Organic Carbon and Its Relationship to Vegetation Communities and Soil Properties in Permafrost Areas of the Central Western Qinghai‐Tibet Plateau, China
ABSTRACT Soil organic carbon (SOC) contents were examined beneath two grassland vegetation communities and cold desert sites in permafrost areas of the central western part of the Qinghai‐Tibet Plateau. Mean SOC stocks in the top 150 cm were 7.73 kg m ‐2 for Stipa roborowskyi communities and 3.72 kg...
