Land use/cover change (LUCC) is a key aspect of global environment change and in a sense indicates the influence of human activities on natural environment. Regional case study is the core of LUCC research. The 28th Olympic Games will be hold in Beijing. The Olympic Green locates in northern Beijing, where there are villages, residential houses, arable land and commercial building. In order to detect the changes of land use in the past several years and monitor the change of the Olympic Green and the construction implementation in the past four years, one Quickbird image of 2002 and three aerial true color images of 2003, 2004 and 2005 in May or July are used to monitor the change and the location of construction, green land, water body after standardized radiometric normalization correction and geometrical correction. The land use changes during the past four years were statistically analyzed by the interpretation of the images that show clearly the location of the housebreaking area and the progress of the Olympic main venue construction area.
