摘要 本文对比分析了2003—2012年31省粮食统计数据,认为四川粮食生产的基础性指标(种植总面积与粮食总产)没有发生显著变化,但是粮食生产的发展性指标在粮食主产区及西部地区已经没有比较优势:粮食种植面积与产量占全国的比重逐年下降,粮食种植面积与产量的增量与增速均低于全国平均水平,粮食单产仅与全国平均水平相当。分析了四川土、水、肥、药、机、人、灾、钱等各粮食生产要素的科技问题,认为四川粮食生产面临耕地面积刚性减少、耕地质量下降、农民种粮效益低下、乡村劳动力不断减少、自然灾害严重、科技支撑能力不足等科技挑战。

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
