利用地理信息系统（GIS）和空间重心分析方法对江苏省水稻种植面积和产量进行时空的变迁研究.结果显示,1949—2011年间,江苏水稻种植面积和产量的空间重心呈现区域性迁移特征,经历以苏南地区为主完全转变成以苏北地区为主的变迁过程.其中,种植面积空间重心从镇江扬中市三茅镇扬子东路开始,途经江都市十三圩等地进入高邮市,经萧家庄、郑家等地到达宝应县周庄和任庄;总产量迁移轨迹与种植面积总体接近、稍有差异.并从人口、政策、经济和科技四个方面对空间重心变迁的驱动进行了讨论,运用相关系数计量研究了水稻与人口和经济之间的关联程度.

Based on the systemized historical data of Jiangsu＇s rice acreage from 1949 to 2011,and with the meth-ods of GIS and space gravity analysis,this paper explored the changes in time and space in the gravity of Jiangsurice acreage. The results showed that,during this period,the space gravity of Jiangsu＇s rice acreage and yieldchanged from the south area-based to the north area-based,with the characteristics of regional transfer. Thespace gravity was shifted from East Yangzi Road,Sanmao Town,Yangzhong City of Zhenjiang Municipality,through Shisan Yu Village Area,Jiangdu City,to Gaoyou City,still through Xiaojia Village and Zhengjia Villageareas,finally to Zhouzhuang Village and Renzhuang Village,Baoying County. The total rice yield was shifted alongthe same route as the rice acreage gravity,with only slight variations. The paper also discussed the driving forcesbehind these changes from the perspectives of population,policy making,economy and science and technologylevel. Also addressed was the relationship between rice and population and economy with relevant coefficientquantitative research method.
