 note = {To accurately estimate soil organic carbon (SOC) storage in upper alpine to nival zones on the Tibetan Plateau, we inventoried SOC pools in 0-0.3 m profiles along an altitudinal gradient (4400-5300 m asl). We also studied vegetation properties and decomposition activity along the gradient to provide insight into the mechanisms of SOC storage. The vegetation cover and belowground root biomass showed a gradual increased with altitude, reaching a peak in the upper alpine zone at 4800-4950 m before decreasing in the nival zone at 5200-5300 m.Decomposition activity was invariant along the altitudinal gradient except in the nival zone. SOC pools at lower sites were relatively small (2.6 kg C m^<-2> at 4400 m), but increased sharply with altitude, reaching a peak in the upper alpine zone (4950 m; 13.7 kg C m^<-2>) before decreasing (1.0 kg C m^<-2> at 5300 m) with altitude in the nival zone. SOC pool varied greatly within individual alpine meadows by a factor of five or more, as did bulk density, partly due to the effect of grazing. Inventory data for both carbon density and bulk density along altitudinal gradients in alpine ecosystems are of crucial importance in estimating global tundra SOC storage., チベット高原の高山帯上部から植生限界（標高4400 m‐5300 m) において、深度30 cmまでの土壌圏有機炭素(SOC)プールの測定を行った。また綿シートを用いて標高傾度に伴う分解活性の差異を検討した。低標高ではSOCプールは小さく（2.6 kg C m-2, 4400 ｍ）、標高が上がるにつれて増加して4950 ｍで最大（13.7 kg C m-2）となった。分解活性は植生限界である5200－5300 mを除くと、ほとんど変化しなかった。標高のわずかな違いによってSOCプールや仮比重は大きく変動し、高山ツンドラでのSOCプールの推定において標高傾度に伴う調査が重要であることが示唆された。},
