Drastic land use/cover changes have always taken place in the urban fringe area in the urbanization, which always aroused many environmental and ecological problems, such as pollution, biodiversity loss, local climate change and so on. Thus, with the support of RS data and field investigation data, the driving forces of the land use/cover change in the urban fringe area of the west part of Beijing city is analyzed and evaluated in this paper. The results show that the land use/cover changes in the urban fringe are affected collectively by many factors in different scales. Human activity changed the landscape characteristics of the fringe as a whole and the rapid economic increase and fast urbanization were the key driving forces of the land use/cover change in the urban fringe area. In addition, the investment and industry transformation of the urban area and the structure adjustment in the primary industry of the rural area drove the land use/cover change directly in the regional scale and the location factors such as traffic situations, landform and so on, affected the land use/cover change in the urban fringe in the local scale. Besides, human behaviors also affect the land use/cover changes in the urban fringe in some extent.
