| 摘 要： | 1. IntroductionAccording to the reconstruction of paleo-temperature based on δ18 O data of ice core in theGreenland (see Jouzel et al., 1987; Grootes et al.,1993; Blunier and Brook, 2001), the current inter-glacial epoch, the Holocene, began at ca. 11.5 thou-sand years before present (ka BP). Multiple sources(pollen data, macrofossils) reveal that the summer cli-mate in the Northern Hemisphere was warmer in theearly to middle Holocene (MH) (ca. 8-6ka BP) relativeto the present climate. …

| Abstract: | A better understanding of the long-term global carbon cycle required estimate of the changes in terrestrialcarbon storage after the last glacial period. The results of simulation at mid-Holocene (MH) from PMIP(Paleoclimate Modeling Intercomparison Project) and the modern data from CRU (Climate Research Unit,East Anglia University, UK) allow us to use the Atmosphere-Vegetation Interaction Model (AVIM) tosimulate the Chinese terrestrial net primary productivity (NPP) at 6ka BP and present time. The changeof NPP and total NPP in China from now to mid-Holocene are about 54 g m-2yr-1 and 0.63 Pg yr-1,respectively, mainly due to the build-up of temperate forest and tropical rainforest. Chinese terrestrial NPPvariation from MH to now is closely related to the variation in intensity of Asian monsoon, which controlledthe climate-vegetation pattern change. |
