Abstract：Taking the tributary of Jinsha River， Maguohe River Basin， as research object， we studied the change of land use type and vegetation resulted from hydropower development based on GIS and buffer analysis. Fractal dimension， patch density， edge density， contagion index and Shannon diversity are chosen to quantify the landscape pattern change. The results show that land use has changed in the basin. The area of artificial surface and paddy field increased significantly， while the area of the grass， water， shrubs reduced. However， the main vegetation type is still forest in the basin. Vegetation coverage has changed little， but the area with high vegetation coverage has decreased. The hydroelectric project might enhance landscape heterogeneity. Landscape pattern changed significantly within 1 000 m buffer zone.
