| 摘 要： | 【目的】分析江苏省1980—2009年水稻生产地域格局的变化及影响因素，探究工业化和城镇化进程加快对江苏省水稻生产地域格局变化的影响，为江苏省水稻生产的可持续发展提供科学决策依据。【方法】基于1980—2009年的统计数据，运用数理统计和区域差异的研究方法，探讨江苏省近30年水稻生产地域格局变化的特征及其影响因素。【结果】近30年江苏省水稻种植面积变化区域差异明显，苏南地区快速减少，苏中地区略有减少，苏北地区快速增加；水稻单产区域差异减小，苏南地区水稻单产优势逐步削弱，苏中地区成为当前江苏省水稻生产的单产优势地区，苏北地区与苏南地区、苏中地区的单产差距逐步缩小；苏南地区水稻总产在江苏省的比重不断下降，苏北地区在全省水稻生产中的比重明显上升。【结论】种植结构调整和耕地面积变化是江苏省水稻种植面积区域差异的影响因素，其中种植结构调整是主导因素；水稻单产的区域变化是耕地质量变化、气象因子和社会因素等综合影响的结果；苏南地区工业化和城镇化的快速推进导致了该地区水稻种植面积的下降和单产优势的削弱，促使江苏省水稻生产的重心由苏南地区逐步转移到苏北地区。

| Abstract: | 【Objective】In order to provide a basis of scientific decision-making for sustainable development of rice production in Jiangsu Province,the regional pattern changes of rice production from 1980 to 2009 in Jiangsu Province and its influencing factors were analyzed for exploring the influence of acceleration of industrialization and urbanization on regional pattern changes of rice production in Jiangsu Province.【Method】Based on the statistical data from 1980 to 2009,regional pattern changes of rice production in Jiangsu Province and its influencing factors were discussed with the methods of mathematical statistics and regional difference in recent thirty years.【Result】In the last thirty years,great changes had taken place in rice planting area of different regions in Jiangsu Province,with the characteristics of quick decrease in South Jiangsu area,slight decrease in Central Jiangsu area,and quick increase in North Jiangsu area.Rice yield advantage in South Jiangsu area gradually weakened,Central Jiangsu area became currently prevailing area of rice yield in Jiangsu Province,and the difference between North Jiangsu area and South Jiangsu area,Central Jiangsu area was decreasing gradually.The proportion of rice output of South Jiangsu area to the whole province declined continuously,and that of North Jiangsu area to the whole province rose obviously.【Conclusion】Adjustment of planting structure and change of cultivated land area are the influencing factors of regional difference of rice planting area in Jiangsu Province,while adjustment of planting structure is the leading influencing factor.Regional change of rice yield is influenced synthetically by change of cultivated land quality,meteorological factor and social factor.Acceleration of industrialization and urbanization of South Jiangsu area results in the decrease of rice planting area and the weakening of rice yield advantage,which gradually makes the major region of rice production in Jiangsu Province transfer from South Jiangsu area to North Jiangsu area. |
