Abstract:Based on the data of the continuous annual natural runoff and agricultural drought rate within a period of 52 years(1956~2007), VIC model and the series of water resources amounts of the calibration period(1961~1990) and the prediction period(2009~2060) with three climate patterns(NCAR、CSIRO、MPI)under A1B scenario simulated with the water balance model, the future agricultural drought rate in China is predicted herein, and then the changing trend of the drought in the future is also analyzed with the Matlab based model of the correlation between runoff and agricultural drought rate on the basis of taking the main river basins in China as the study areas.
Keywords:climate change  drought  river(lake) basin  agricultural drought rate  natural runoff
