| 摘要: |
| 该文基于2001～2011年江苏省77个县市种植业总种植面积及6类主要农作物种植面积数据，运 用产业集聚方法中的重心移动法、区位基尼系数法和莫兰指数法，对江苏种植业整体地理集聚格局演变进 行分析，结果表明:江苏省种植业重心快速向西北方向移动，集聚程度逐年增大，苏北、苏中、苏南种植 业集聚具有明显的地域梯度特征。运用上述方法分析6类主要农作物（小麦、稻谷、玉米、棉花、油料、 蔬菜）2001～2011年的重心演变轨迹、集聚程度和高值集聚区作具体分布，结果显示:除了棉花，其他农 作物重心都快速向北移动; 6类农作物基尼系数都大于0，说明都存在集聚现象;高值集聚区在苏北都有分 布; 6类农作物在2008年地理集聚显著。并且具体阐述了6类主要农作物的集聚趋势。在分析集聚的基础 上，从物质装备、效益、政策3个方面论述了江苏省种植业集聚驱动力。 |

| Abstract: |
| Based on the data of total planting area of 77 counties of Jiangsu province from 2001 to 2011 and six main crops planting area， using the method of industrial concentration which including the Center of Gravity Move method， Gini Coefficient method and Moran Index method， this paper analyzed the general geographical agglomera- tion pattern evolution of planting industry in Jiangsu province. The results showed that the plant industry moved for- ward northwest of Jiangsu province， and the agglomeration degree increased year by year， which showed obvious ge- ographical gradient features in north， middle and south Jiangsu. Moreover， the planting evolution track， agglomera- tion degree and distribution of high value agglomeration area for six kind of main crops（wheat，rice，corn，cot- ton，oil and vegetables）from 2001 to 2011 were analyzed: The planting center of all the crops， except cotton， moved to north; Gini Coefficients of the six crops were greater than 0， which indicated that there was agglomeration phenomenon; High value cluster areas distributed in north Jiangsu. Finally， the agglomeration trend of the 6 major crops was also discussed， and the agglomeration driving forces were analyzed from the aspects of the material and e- quipment，benefits，policy in Jiangsu Province. |
