【摘要】：基于城乡一体化的思想构建乡村性指数(RI),运用熵值法确定2001~2012年乡村性指数的权重,以乡村性指数为变量,运用差异系数对江苏省乡村性县域差异的演变过程与空间格局进行定量分析。结果表明:2001年以来,江苏省乡村性随着城市化水平的提高呈现不断减弱的趋势,县域乡村性在2001~2007~2012年表现为总体缩小基础上的先缩小后扩大的演变格局。县域乡村性各子系统发展不平衡,主要表现为土地利用差异,人口发展、经济发展和基础设施差异相对较小。在空间上,县域乡村性呈现由苏北苏中地区向环太湖和宁镇地区不断极化的过程。其中苏南地区以向下收敛为主;苏北地区以向上收敛为主;苏中地区以向上发散为主。
[Abstract]:Based on the idea of urban-rural integration, the ruralness index is constructed, and the weight of ruralness index from 2001 to 2012 is determined by entropy method, and the ruralness index is taken as variable. This paper makes a quantitative analysis of the evolution process and spatial pattern of the rural county area difference in Jiangsu Province by using the coefficient of difference. The results show that since 2001, the rural nature of Jiangsu Province has been weakening with the improvement of urbanization level. From 2001 to 2012, the rural area of the county showed the evolution pattern of first shrinking and then expanding on the basis of the overall reduction. The development of the sub-systems of the county rural was unbalanced, mainly manifested in the difference of land use and the development of the population. The difference between economic development and infrastructure is relatively small. In space, the rural area in the county area shows a process of continuous polarization from the central area of northern Jiangsu to the areas around Taihu Lake and Ningzhen, in which the south of Jiangsu mainly converges downward; The northern part of Jiangsu is mainly convergent upward, while the central part of Jiangsu is dominated by upward divergence.
