Application of the Residual GM(1,1) Calamities Model to Aridity Forecast in Sichuan

摘要：

Based on the data of crop aridity area in Sichuan since 1949, We apply the grey system theory and modeling grey calamities residual GM(1,1) with the year series of various threshold of drought acreage. Combining inclusion relation of drought predication years sets, We make improvement on forecast reliability of residual GM(1,1) calamities model in Sichuan aridity.
