This paper presents an integrated study about the urban expansion process in Beijing from 1973 to 2013. Annual urban expansion area index, gravity center transfer model, fractal dimension index and the elastic coefficient or urban expansion-population growth are employed to explore the temporal and spatial characteristics of urban expansion. The results reveal that urban expansion of Beijing underwent seven different expansion stages, including one slow and steady expansion stage, three fast expansion stages, three shot deceleration stages, in the past 40 years. The centroid of urban lands moved to the southeast and urban boundaries became more and more complex and irregular. Urbane expansion speed was not harmonized with population growth distinctly in 1987-1998, 2000-2003 and 1998-2000. This study can provide scientific data for urban planning of Beijing and related studies of urban expansion in depth.
