【Abstract】 Investigates a method of time series model with grey system model. Rules in time series can be found by GM(1,1) model and the trend of the time series can be forecasted. In addition, GM(1,1) model of the grey theory is applied to the forecast of the development of cultivated land and grain production in China in next 10 years, and the forecast results is as nearly same as the results from some famous scientists. So, GM(1,1) model is a useful method in mining time series models.更多还原
