中文摘要：

综合应用变异系数、地理联系率、区位熵等区域差异分析方法对江苏省1980年以来地级市尺度的粮食生产和经济发展地域格局变化特征进行了联动分析。研究发现：江苏省粮食生产经历了一个“上升-平稳-下降”的波动过程；地域差异增大，尤其是1995年后，粮食生产与经济发展、人口分布发生明显的空间分异；长江以北地区，特别是苏北地区在全省粮食生产地域分工过程中扮演着越来越重要的角色，日益成为江苏省粮食生产核心区域。最后，结合耗散结构理论，分析了江苏省粮食生产地域格局变化的驱动因素，并提出了相关建议。

英文摘要：

Investigating the regional pattern changes of grain production has a great importance to grain production distribution and optimization in the new period. Based on the methods of regional difference analysis, the regional pattern changes of grain production in Jiangsu Province since 1980 was discussed. The study showed that grain production in Jiangsu Province experienced a process of ＂rising- stable- degressive＂. Regional difference of total output enlarged. The study also indicated the existence of spatial differentiation among grain production economic growth and population distribution especially after 1995. The north of Yangzi River, especially the Subei region has been playing a more and more important role in the regional division of grain production, and becoming the kernel area of grain production in Jiangsu Province. Combining with the theory of dissipative structure, this paper analyzed the driving factors of regional pattern changes of grain production and finally put forward some related suggestions.
