Abstract:: Based on Landsat TM images of Chongzuo City, Guangxi in 2001 and 2010, fractal theory was applied to study the spatiotemporal pattern of the morphological complexity and structural stability of land use types in this area during the past 10 years under the support of remote sensing, geographic information techniques and statistical analysis tools. The results showed that: (1) the distribution of all land use types in 4 border counties or cities of Chongzuo City had fractal characteristics, on the whole, the shapes of each land use patch were regular, and the structure was stable in 2001 and 2010; (2)the fractal dimensions of each land use type had been gradually rising and approaching the critical value of 1.5, while the stability indexes continued to decrease towards 0, which led to the land use types to present the fractal evolution trend of high complexity and low stability; (3) the water of Daxin County and Longzhou County and the woodland and garden plot of Pingxiang City and Ningming County had the most obvious tendency of rising complexity and declining stability, on the contrary, the unused land of Daxin County and Longzhou County and the grassland of Pingxiang City and Ningming County changed the least; (4) in the future, Chongzuo City should strengthen the guidance for land use planning, and take effective measures to control increases in fractal dimension and maintain the stability of land use structure.
