Description :
This study simulated the net primary productivity (NPP) of China's ecosystems based on the dynamic global vegetation model (DGVM) Integrated Biosphere Simulator (IBIS) with data on climate, soil, and topography. The applicability of IBIS in the NPP simulation of China's terrestrial ecosystems was verified first. Comparison with other relevant studies indicates that the range and mean value of simulations are generally within the limits of observations; the overall pattern and total annual NPP are close to the simulations conducted with other models. The simulations are also close to the NPP estimations based on remote sensing. The AA. then simulated NPP with climate change data from 1961 to 2005, when warming was particularly striking. The results highlighted that NPP declined in spring, summer, and autumn in the Loess Plateau but increased in most parts of the Tibetan Plateau.
