平原农区村庄迁居安置意愿空间特征及其与通达性关系——以江苏省淮安市为例

Spatial Features of Willingness to Resettlement and Its Relations with Accessibility at Village Scale in Plain Area:A Case Study of Huai’an

准确揭示村庄迁居安置意愿的空间特征及其与村庄通达性的关系,对于推动乡村聚落体系重构和合理发展就地城镇化具有重要意义。文章选择淮安市为研究区,以全样本行政村调查数据和交通网络数据为支撑,利用描述统计分析、GIS空间分析与表达、熵权-TOPSIS模型等方法进行实证研究。研究发现:①村庄迁居安置意愿(Y)空间差异不甚明显,而货币迁居安置意愿(Y_(1))的空间差异高于实物迁居安置意愿(Y_(2))。Y、Y_(1)和Y_(2)都存在空间自相关现象。②外部连通性对村域综合通达性(C_(i))的贡献最大,C_(i)呈现明显的空间差异特征,市域北部平原村庄C_(i)高于南部低山丘陵和中部河网密布地区村庄。③Y_(1)、Y_(2)和C_(i)在市区和县城周边都表现出明显的圈层分异特征。其中,Y_(1)是内圈低外圈高,而Y_(2)和C_(i)是内圈高外圈低。④在迁居安置意愿与通达性的空间耦合关系上,L(Y_(1))-H(C_(i))、H(Y_(2))-H(C_(i))空间耦合村庄集中分布在城区外围,主要原因是这些村庄因近城区优势区位,能得到实物安置潜在的预期增值和享受较高的公共服务。各类空间耦合区和同类空间耦合区的不同片区形成原因也不尽相同。

Accurately revealing the spatial features of willingness to resettlement and its relations with accessibility at village scale is of great significance for promoting the reconstruction of rural settlement system and urbanization development.Selecting administrative villages in Huai’an as the research area,this paper uses the methods of descriptive statistical analysis,GIS spatial analysis and entropy-TOPSIS model to do empirical research based on the survey data about resettlement willingness and the traffic network data.There are some findings as follows:1)In terms of the spatial difference of resettlement willingness,the village resettlement willingness(Y)is not obvious,and the spatial difference of resettlement willingness with money(Y_(1))is higher than that of resettlement willingness with house(Y_(2)).Moreover,there are spatial autocorrelation phenomena between Y,Y_(1)and Y_(2).2)Among the 4 sub-factors of village comprehensive accessibility(C_(i)),the external connectivity has the greatest impact on it.C_(i)in the north plain is higher than that in the south section of Huai’an where there are low mountains and hilly or dense river network.3)Y_(1),Y_(2)and C_(i)all show obvious C_(i)rcle distribution around the urban district and the county town.The distribution of Y_(1)is lower in the inner ring than in the outer ring,while the distribution of Y_(2)and C_(i)are opposite with it of Y_(1).4)In terms of spatial coupling between resettlement willingness and accessibility,the villages with L(Y_(1))-H(C_(i))and H(Y_(2))-H(C_(i))distribute in the periphery of the urban district and the county town.The main reason is that the village near the urban and county town can get the expected value-added of house for resettlement and enjoy higher public services.As the reason,it is different for the formation of various spatial coupling areas and different areas in the similar spatial coupling areas.
