Landsat remote sensing satellite images in different years were used to analyze land use change in the Fuping Basin

then the hydrological and meteorological data during 1968-2010 was used into SWAT model for analyzing the impact of land use change on runoff. In recent decades，the change of precipitation is not obvious，while the change of runoff shows a significant trend of decreasing. Increased watershed woodland (grassland turns to woodland) is the main reason for reducing runoff. Runoff decreased by 6.46% with the change of woodland area from 926 km

in 1993 to 1119 km

in 2004. Simulated average annual runoff under different scenarios overall decreased. Increasing of woodland and decreasing of grassland can lead to a reduction of runoff. Changes of woodland and grassland affect the hydrological cycle through affecting the evapotranspiration. The change trend of runoff shows a negative correlation with the evapotranspiration.
