Abstract: In order to study the relationship between the forest landscape change of Gaoligong Mountain and its driving force, remote sensing satellite images of 1974, 1987, 1997 and 2006 in Gaoligong Mountain were obtained and interpreted. The cost-distance analysis was used to study the effect of villages and roads on forest landscape change, and function fitting was carried out to explore the relationship between cost-distance and landscape spatial change. The results indicated that the variation of forest in Gaoligong Mountain showed a trend of first increase and then decrease, the changes of forest were obvious in the elevation of 1000-2000 m. There was a significant correlation between forest changes and villages and roads, mathematical fitting showed high significance.
