摘　　要：根据四川省1978~2013年粮食产量统计数据和社会经济资料,揭示了36 a来四川省粮食总产量和人均粮食产量的变化趋势和特征;运用主成分分析和相关性分析方法,对四川省粮食产量与社会经济相关指标进行分析,结果表明四川省粮食生产与农业生产条件的改善、农民对粮食生产的投入增加和对耕地资源的依赖有着密切的联系。According to the statistical and survey data of Sichuan Province, the change trend and characteristics of the province＇s total grain yield and per capita grain yield during the last 36 years were discussed in this paper. The principal component analysis and correlation analysis of the grain yield and the community economy showed that the improvement of agricultural production condition, the increase of farmers＇ investment in the grain production and the dependence on the land resources were closely related with the grain production and yield of the province.
