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。

英文摘要：

According to the meaning of region,which can be regarded as a unity of urbanity and rurality,taking unban as criteria of reference,we constructed the evaluative indices system of rurality index and used entropy method to estimate the rurality on the county scale in Jiangsu Province from 2001 to 2012.Taking rurality index scores as variables,we also used coefficient of variation to quantitatively analyze the process and pattern of rurality on the county scale in Jiangsu Province.The results are as follows.Firstly,since the beginning of the new century,with the improvement of the level of urbanization,rurality index in Jiangsu Province has shown the trend of reduction.The evolution of rurality on the county scale showed the special pattern.From 2001 to 2007,the differences narrowed gradually.Then from 2007 to 2012,the differences expanded little by little.Secondly,the development of rurality sub-system was out of balance.The sub-system had significant difference in the land use.However,the population development,economic development and infrastructure had relatively little differences.Thirdly,the spatial polarization along Taihu and Ning-zhen region became increasingly obvious.Southern Jiangsu counties gave priority to downward convergence.Northern Jiangsu counties gave priority to upward convergence.The central Jiangsu counties were dominated by upward divergence.Lastly,the spatial and temporal variation of rurality on the county scale was the result of many factors,including location conditions,economic base,infrastructure,social policy,etc.With the development of society and economy,the rurality in Southern Jiangsu area maintained a relatively low level.However,there was an increasing trend in recent years.In order to reduce the rurality in Southern Jiangsu area,it is important to formulate relevant policies to promote the level and quality of urbanization to realize the integration development of urban and rural area.At the same time,the rurality in Northern Jiangsu area was at a high level in a long period.In
