| Abstract: | Based on the grey system theory,this paper analyzes the grey correlation degree of graion yield per unit area and the trend correlation by the model of GM(1,1) in Henan Province from 1999 to 2008.The results of the research show the dynamic trend of the grain yield,which can provide theoretical basises for the stable development of grain yield in Henan Province. |
