Abstract:

For the purpose of predicting the future urban evolution trends and elaborating rational policies for regulation and control, it’s significant to distinguish correctly the rules of urban expansion and to analyze the evolution process. Offering rich variable data of urban expansion, the earth observation technology of remote sensing becomes the main approach to monitor urban expansion. Based on the TM images in 1988, 1996 and 2004, the article applies RS, GIS and land use degree comprehensive index to extract the boundary of urban entity of Beijing, and analyzes the area, direction, type and rules of Beijing urban expansion between 1988 and 2004. It’s indicated that urban expansion of Beijing developed rapidly in 16 years, and greatly influenced by terrain, environment, satellite cities, traffic circulation and the government.

Key words: Beijing, land use degree comprehensive index, RS, urban entity, urban expansion
