    摘要:

    以长江三角洲为研究区域,构建乡村性RI理论公式,测度2000-2012年县域单元的乡村性;通过Moran’s I、LISA集聚图及空间变差函数,对转型期长三角县域乡村性空间格局特征进行了初步的探讨。结果表明:长江三角洲县域乡村性非均衡性显著,乡村性较弱的县域所占比重略大,县域乡村性整体上呈现出弱的分布态势;县域乡村性全局表现出空间集聚的自相关性,H-H集聚区集中在通泰扬和台州,L-L集聚区主要分布在苏锡常地区;县域乡村性空间格局的连续性和自组织性越来越强,空间自相关引起的结构化分异较显著,且空间分布表现出一定的各向异性,从东南—西北方向县域乡村性呈“塌陷型”的空间分布结构;最后,有针对性地提出转型期长三角地区乡村发展重构的具体策略。

    Abstract:

    At present, our country economic and society are in transition period, rural and urban development also are experiencing a transition period, from society, economy, culture and settlement spatial, rural become to urban transformation. This paper talked the Yangtze river delta for example, based on every region can be regarded as a unity of urbanity and rurality, taked urban as criteria of reference to construct rurality index, by using spatial metric model such as spatial correlation index, semivarigram and LISA, preliminary analyzed the spatial pattern of rurality in Yangtze River Delta since the 2000s. The results showed that: county rurality was unbalance, weak rurality of county was a slightly larger proportion, presented weak rurality distribution situation; county rurality global presented the spatial agglomeration distribution correlation, high-high agglomeration areas were located in Nantong-Taizhou-Yangzhou and Taizhou, low-low agglomeration areas were mainly distributed in Suzhou-Wuxi-Changzhou; the county rurality framework tended to be more continuous and self-organized, spatial autocorrelation caused by structural differentiation was more significant, space distribution showed some anisotropy, county rurality in northwest-southeast direction appeared “collapse” spatial distribution structure; at last, putted forward specific strategies to reconstruct the rural development in Yangtze river delta during transformation period.
