中心城市对农村空心化格局影响的尺度效应——以河南省为例

Scale Effect of Center City Impact on Geographic Distribution Pattern of Rural Hollowing: A Case Study of Henan Province

基于宏观和微观两个视角研究不同层级的中心城市对周边农村地区空心化格局的影响。以河南省为例,首先,确立省级和县级两个不同层级中心城市(郑州和兰考)作为参照系。其次,建立农村空心化程度评价指标体系,分析其影响效应,采用实地调研的数据来确定村庄的空心化程度。结果表明:省级中心城市对周边腹地农村空心化影响为正,县级中心城市对周边腹地农村空心化影响为负。并且,两个尺度下交通干线附近农村空心化程度都普遍较高。最后,运用城市在区域经济中发挥的集聚和扩散效应对研究结果加以解析。

Based on the macro and micro perspective,this paper studies the influence of different sizes of central cities on the geographic distribution pattern of hollowed village. Firstly,establish two different sizes of the central city as a reference system,they are the provincial central city of Zhengzhou and county center city of Lankao.Then,using different methods to establish the evaluation system of rural hollowing degree. In the study of the impact of the provincial central city on the spatial distribution of rural hollowing,the county as the basic research unit using comprehensive index evaluation method to determine the degree of rural hollowing in each county. In the study of the impact of the county-level central cities on the spatial distribution of rural hollowing,the village as the basic research unit using the data of field research to determine the degree of rural hollowing in each village. The study shows that the provincial capital city has a positive impact on the hollowing village of rural hinterland. County-level central city has a negative impact on the hollowing village of rural hinterland. Moreover,no matter what scale the degree of hollowness in rural areas near the traffic arteries is generally high. At last,using the agglomeration and diffusion effects of cities in regional economy to explain this phenomenon.
