A study was conducted to investigate the dynamic changes of landscape patterns in Beijing City in terms of landscape pattern indexes based on the Landsat-TM images in 1985, 1995, 2000, and 2007. Results showed that the patch types changed little, and component area and patch numbers changed significantly. Among all the land use patterns, urban built-up area increased by 7.66% of the total area, and farmland and forest land decreased gradually. The total patch number increased first and then decreased, indicating a decreasing tendency in total. The patch number of arable land and forest land increased obviously. Natural and semi-natural patches were highly influenced by human disturbance. The distributions of landscape patch types tended to aggregate due to human disturbance. Patch shapes are more simple and regular especially for the main landscape patch patterns, which result in an obvious change in landscape pattern indexes. Urbanization process has a significant impact on landscape patterns in Beijing.
