| 摘 要： | 根据1998-2008年江淮丘陵区统计资料,对该区粮食生产的时空变化特征进行了研究,在此基础上,进一步对影响该区粮食生产的诸多要素进行了灰色关联分析。结果表明,粮食播面比、受灾、化肥施用量是影响该区粮食生产时空变化的相对活跃因素。

| Abstract: | Based on statistical data of Jianghuai hills land in 1998-2008,the space-time variation characters of foodstuff production in this area were studied.On this basis,grey correlation analysis was performed on many primary factors influencing the foodstuff production in this area in further study.The results indicated that sowing area ratio of foodstuff,suffering disaster and dosage of chemical fertilizers were relatively active factors influencing the space-time variation of foodstuff production in this area. |
