| 摘 要： | 以江苏省65个县市为研究实证单元,基于区域城乡一体的思想构建乡村性指数,对县域尺度上江苏省乡村性进行定量评价,以ArcGis 9.3、GeoDa 095、SPSS 16等软件平台为支撑,采用Jenks最佳断点分类、空间自相关分析方法,对县域尺度江苏省乡村性的空间分异进行定量地分析与研究。结果表明:县域尺度江苏省乡村性差异性不显著,但乡村性较强区域所占比重略大;从苏南到苏北呈现乡村性梯度递增的空间分异特征;全局上呈乡村性集聚分布态势,局部上在江阴、昆山等7县市和苏北灌云、阜宁等7县形成县域尺度的乡村性"冷点区"与"热点区"。

| Abstract: | By taking 65 counties and cities of Jiangsu Province as empirical units,rurality indexes have been constructed based on regional urban-rural integration,and a quantitative evaluation has been conducted on the rurality of Jiangsu Province based on county scale.With the support of ArcGis 9.3,GeoDa 095 and SPSS 16,by adopting Jenks best breakpoint classification and spatial autocorrelation analysis,a quantitative analysis and research have been conducted on the spatial differentiation of rurality of Jiangsu Province.The results show that rural difference of Jiangsu Province based on county scale is not remarkable,and the area with strong rurality takes a larger proportion;rurality increases from South Jiangsu to North Jiangsu progressively;rurality concentrates in general,seven counties and cities including Jiangyin and Kunshan City are "cold spots" while seven counties and cities including Guanyun and Funing City are "hot spots" of rurality. |
