The conclusions are as following: The fluctuation of purveyance production is related with grain yield, especially the production of maize is the dominant factor. Analyzed from the viewpoint of the crop construction, the fluctuation of grain yield is related significantly with both grain yield per hectare of maize and wheat and the planting area of maize and rice.
