| 摘 要： | Based on Atmosphere-Vegetation Interaction Model （AVIM）, the magnitude and spatial distribution of terrestrial net primary productivity （NPP） in China is simulated during three different geological eras, Last Glacial Maximum （LGM）, Mid-Holocene （MH） and the present. The simulation shows that the glacial-interglacial variation of East Asian summer monsoon in China is the key factor affectfng the NPP change. During the three eras, mean NPPs are 208 g/m^2·a, 409 g/m^2·a, and 355 g/m^2·a. The total NPPs are 2.05 Pg/a, 3.89 Pg/a and 3.33 Pg/a, respectively. The terrestrial NPP in China during warm-humid climate is larger than that during cold-arid eras, and the correlation analysis between NPP and climate factors suggests that temperature is the primary factor affecting the terrestrial NPP during 21 kaBP （LGM）, and for 6 kaBP （MH） and the present the primary factor is precipitation.
