WANG Jianlin %A HU Dan %A SUN Zibao %J 地理学报(英文版) %D 2003 %I %X Based on climate material, the simplified terrestrial carbon cycle balance (TCCB) model was established, which is semi-mechanism and semi-statistics. Through TCCB model, our estimate indicates that the southeastern part of the Tibetan Plateau has much higher carbon content, and we have calculated the litter carbon pool, NPP, carbon fluxes and described their spatial characteristics in this region. Based on the TCCB model simulation, NPP in Tibet is 1.73 X 108tC/a, soil organic input rate is 0.66 × 108 tC/a, litter mineralization rate is 1.07 × 108 tC/a, vegetation litterfall rate is 1.73 ×108tC/a, the litter carbon pool is 7.26 × 108 tC, and soil decomposition rate is 309.54 × 108 tC/a. The carbon budget was also analyzed based on the estimates of carbon pool and fluxes. The spatial distributions of carbon pools and carbon fluxes in different compartments of terrestrial ecosystem were depicted with map respectively in Tibet. The distribution of NPP, vegetation litterfall rate, litter, litter mineralization rate, soil organic input rate and the soil decomposition rate were abstracted with temperature, precipitation, fractional vegetation and land feature. %K Tibetan Plateau %K terrestrial ecosystem %K carbon cycle %K model
