Abstract :
Detailed description of land use/land cover change of China during the past hundred years not only help us understand the impacts of human-induced land use/land cover change on climate change and carbon cycles, but also reflect the true role of land use/land cover change of China in the global climate change. Hence, this article tries to propose a methodological framework on the reconstruction of China´s higher temporal and spatial resolution of land use/land cover datasets. We take the existing 1 km gird national land use/land cover raster datasets as a basis, make full use of the statistical data from land use survey and historical data since 1911, and collect topography, soil, climate, population, economy, policy as auxiliary data. And then establish a cellular automata model on GIS platform to calculate and distribute land use/land cover in the history times´ year by year.
