- Abstract:
- BIOME-BGC model was used to estimate net primary productivity (NPP) of Robinia pseudoacacia forest and analyze the effect of climate change and different CO2 concentrations on them in Beijing Mountain Area during the period of 1974-2010. The results showed that simulated NPP were lower than measured values showing wave-shaped changes with an inter-annual variation rate of 11.2%; there was a positive correlation between precipitation and the NPP of Robinia pseudoacacia forest which indicated that precipitation was the key environmental factor controlling the NPP variations; NPP showed positive response to increased precipitation and doubling of CO2 concentration, while increased temperature was not conducive to NPP accumulation; the positive effects of increased precipitation to NPP were inferior to the negative effects of increased temperature; CO2 concentration doubling and increases of precipitation and temperature together could promote NPP with strong interaction.
