| Abstract: | Urban growth is a key issue for urbanization research.Urban growth in Beijing was studied by examining 8 phases of Landsat5 TM images from 1984 to 2007.Urbanization was scaled from those remote sensing monitoring for each of the 8 phases;The index of urban growth rate,urban growth intensity,fractal dimension and compact ratio were combined.Quantitative characteristics,morphology changes and spatial pattern of urban growth were analyzed.The spatiotemporal pattern of urban growth was then outlined. |

| Keywords: | urban growth remote sensing monitoring urban extent extraction spatiotemporal pattern Beijing |
