Over the past two decades, with rapid urbanization in Guangzhou, urban fringes experienced drastically land use changes. In this paper, taking the Extend South Area of Guangzhou as a typical example of urban fringe, based on GIS (Geography Information System) and RS (Remote Science) technology, land use vector of the study area in 1990, 1995, 2000 and 2005 were interpreted from Landsat TM images. Dynamic degree, fractal dimension and stability index of each main land use type in each year were calculated. Results showed that: from 1990 to 2005, land use of the Extend South Area of Guangzhou experienced obvious changes under the strong forces of urbanization of core area in Guangzhou. According to the change characteristics of land use, two phases of study period are followings. Firstly, from 1990 to 1995, the structure of land use changed tempestuously. In this period, the increase of construction land and decrease of farmland was the main process, with great increase of fractal dimension and decrease of stability index. Secondly, from 1995-2005, increasing speed of construction slowed down, farmland and forest land started to increase, and increase of fractal dimension and stability index became slighter, regional structure of land use experienced a beneficial development.
