摘 要：A model is established for assessing the effects of climate change on runoff in China based on the land surface parameter-ization scheme variable infiltration capacity (VIC). The entire area of China is represented by 2604 cells with a resolution of 60km×60 km for each cell. Forcing data, soil and vegetation parameters needed by the VIC model for the entire area of China are prepared. Dailyforcing data, which are obtained from 740 stations between 1980 and 1990, are interpolated to the 60 km×60 km grid system. The VICmodel is run on every grid cell over the whole China, and a routing scheme is run offline with daily input of surface runoff and drainagefrom the VIC to get hydrograph at basin outlets. The spatial patterns of simulated runoff and mean annual precipitation are consistent verywell. The results of monthly streamflow simulations over the Huaihe and Weihe River basins indicate that there is a good agreement be-tween the observed and simulated values, and also initially indicate the rationalit
