乡村地域多功能的空间关联网络结构特征及其对城乡融合发展的影响--以河南省为例

Structural characteristics of spatial correlation network of rural territorial multi-functions and its impact on urban-rural integrated development:A case study of Henan province

科学探究乡村地域多功能的空间关联关系及其城乡融合效应,是促进区域乡村功能协同提升、城乡融合发展有序高效的重要基础。在厘清乡村地域多功能空间关联机制的基础上,阐释乡村地域多功能空间关联网络的结构特征对城乡融合发展的影响机制,并以河南省为案例区,借助社会网络分析法、面板回归模型等开展实证检验。结果表明:(1)河南省乡村地域多功能的空间关联呈现出日趋复杂的网络结构形态,空间上表现出中部地区密集、外围逐层递减的圈层分异规律。(2)从整体网络结构特征看,河南省乡村地域多功能空间关联网络的网络密度不断提高,网络稳定性逐步增强,但是网络的关联紧密程度仍有待提升。(3)从个体网络结构特征看,新密市、新郑市和禹州市等处于网络的核心位置,而南乐县、商城县和义马市等在网络中处于边缘地位。(4)乡村地域多功能空间关联网络的结构特征对城乡融合发展存在显著的影响,个体网络中心性的提升对城乡融合发展具有显著的促进作用。研究深度剖析了乡村地域多功能的空间交互作用,并揭示了乡村地域多功能的城乡融合效应呈现网络非均衡性特征,可以为乡村联动发展以及县域城乡融合提供理论参考。

Exploring the spatial correlation of rural territorial multi-functions and its impact on urban-rural integrated development is an important basis for realizing the coordinated improvement of rural territorial multi-functions and efficient urban-rural integrated development.This study explains the influence mechanism of structural characteristics of spatial correlation network of rural territorial multi-functions on urban-rural integrated development,and takes Henan province as a case area to carry out an empirical test with the help of social network analysis and panel regression model.The main conclusions are as follows:(1)The spatial association of rural territorial multi-functions in the study area shows an increasingly complex network structure with the annular differentiation,which presents the spatial pattern of"dense in the central region,but sparse in the marginal area".(2)The network density and network stability are gradually enhanced,while the network closeness needs to be improved.(3)Xinmi,Xinzheng and Yuzhou hold the dominant position in the network,while Nanle,Shangcheng and Yima are at the edge of the network.(4)The structural characteristics of spatial correlation network of rural territorial multi-functions have a significant impact on urban-rural integrated development,and the enhancement of the individual centrality plays a significant role in promoting urban-rural integrated development.This study deeply analyzes the spatial interaction of rural territorial multi-functions,and reveals that the urban-rural integration effect of rural territorial multi-functions presents network non-equilibrium characteristics,which can provide theoretical support for rural linkage development and urbanrural integration at county level.
