摘　　要：选取机械动力x1、灌溉面积x2、种植面积x3、化肥用量x4、劳动力x5等5个粮食生产要素,运用SPSS11.5软件进行粮食生产因子分析。结果表明,第1主因子(投入因子)主要由变量x1、x2、x3和x4决定,第2主因子(资源因子)由变量x5决定。对江西省11个市粮食生产能力进行排序,其优先序为:宜春>赣州>上饶>吉安>南昌>抚州>九江>萍乡>景德镇>新余>鹰潭。Grain production safety is a foundation to grain safety. In the paper five production factors of grain power of agriculture machinery（x1）, irrigation area （x2）, the sown area （x3）, consumption of chemical fertilizers（x4） and employed Persons （x5） were analyzed with 11,5 SPSS software and the result showed the first principal component decided mainly from variables x1, x2, x3 and x4, and the second principal component decided from variables x5. The prior order of the grain production capacity in 11 regions of Jingxi were as follows： Yichun 〉Ganzhou 〉 Shangrao 〉 Jian 〉 Nanchang 〉 Fuzhou 〉Jiujiang 〉 Pingxiang 〉 Jing De-zhen 〉 Xinyu 〉 Yingtan.
