This paper discusses four stern difficulties and challenges faced by the development of grain production in China. According to the basic national conditions of China and the amount of grain resource in the world market, China must meet the grain demands mainly by her own domestic production. Using the input-occupancy-output techniques and system science methods, this paper makes a forecast about China's grain output, grain import and self-support rate in the year 2030.
