Abstract：Grain-related statistical data from the year of 2003 to 2012 were analyzed.According to the results,the basic indexes of grain-planting areas and grain outputs kept unchanged in Sichuan province.However,the ratios of planting areas and grain yields to the whole nation were both reduced,the increases and increase radios of grain planting areas and yields in Sichuan were below the average level of the whole nation,and the grain yield per hectare was just equal to that of the nation's average level.As a result,Sichuan was losing its priority in terms of developing indexes of grain production,comparing to its counterparts of main grain-production or western provinces.Many elements related to grain production were analyzed systematically,including quantity and quality of agricultural soil and chemicals,efficiency of water and fertilizer utilization,mechanization,disaster impaction and fiscal expenditure.The results revealed that in recent 10 years,grain production in Sichuan was facing many scientific challenges:area of farmland was reducing,polluted soil was increasing,quality of farmland was deducing,farmers were less likely getting income by planting grains,the number of farmers was declining,agricultural environment was deteriorating
