Forecast of the grain yield based on the trend-state mathematical model
基于趋势-状态预测方法的粮食产量预测

The trend-state mathematical model has the merits of both simplicity of application and high forecasting precision. It can solve the forecast question of data sequences with trend and heavy random fluctuation. This paper forecasted and analyzed the yield of grain in Zhejiang province by this model, which could provide scientific basis for the planed yield of grain.
