Then we calculate the average grain output and the growth rate for China`s grain output degree of dispersion analysis and trend analysis.Analysis shows that if not be too much affected by natural disasters or other economic crisis, Chinese total grain output in the coming years would assume a sustained and steady growth trendency, per capita consumption would continue to increase at the same time.
