摘　　要：A better understanding of the long-term global carbon cycle required estimateof the changes in terrestrial carbon storage after the last glacial period. The results ofsimulation at mid-Holocene (MH) from PMIP (Paleoclimate Modeling Intercomparison Project) and themodern data from CRU (Climate Research Unit, East Anglia University, UK) allow us to use theAtmosphere-Vegetation Interaction Model (AVIM) to simulate the Chinese terrestrial net primaryproductivity (NPP) at 6ka BP and present time. The change of NPP and total NPP in China from now tomid-Holocene are about 54 g m^(-2)yr^(-1) and 0.63 Pg yr^(-1), respectively, mainly due to thebuild-up of temperate forest and tropical rainforest. Chinese terrestrial NPP variation from MH tonow is closely related to the variation in intensity of Asian monsoon, which controlled theclimate-vegetation pattern change.A better understanding of the long-term global carbon cycle required estimateof the changes in terrestrial carbon storage after the last glacial period.
