摘要
城市活力作为刻画城市社会经济发展的重要指标,其定性定量分析已成为研究热点。基于POI数据与夜间灯光遥感数据,运用空间可视化和空间统计分析方法对内蒙古城市白天及夜间活力水平、规模、结构及时空耦合进行测度,并深入分析其空间格局及影响因素。结果表明:(1)内蒙古城市大部分城市活力态势不佳,两极分化明显,活力规模位序转换显著,呈现非均衡化发展特征;(2)活力强度整体上以“扎赉特旗-阿拉善左旗”为分界,形成“南高北低”的分布格局。时空耦合强度呈层状由市中心逐渐向外递减扩散;(3)经济密度、三产占比、信息化程度、科技实力4个因素对内蒙古城市活力空间分异格局的影响较为显著,均具有明显的时空依赖特征。依据研究结果,结合内蒙古城市发展实际,提出相应政策建议。
The qualitative and quantitative analysis of urban vitality, as an important indicator of urban social and economic development, has become a research hotspot. Based on POI data and remote sensing data of night light, this paper used spatial visualization and spatial statistical analysis methods to measure the level, scale, structure and spatio-temporal coupling of daytime and night urban vitality in Inner Mongolia, and further analyzed the influencing factors of its spatial pattern. The results show that:(1) Most cities in Inner Mongolia are not very dynamic, and the phenomenon of polarization is obvious. The change of the order of vitality scale is significant, showing the characteristics of unbalanced development.(2) The distribution pattern of vitality intensity was "high in the south and low in the north", which was divided by "Zhalainte Banner-Alashan Left Banner". The spatial and temporal coupling intensity is layered and gradually diffused from the downtown to the outside.(3) The economic density, the proportion of tertiary industries, the degree of informatization, and the strength of science and technology have a significant impact on the spatial pattern of urban vitality in Inner Mongolia, all of which have obvious spatio-temporal dependence characteristics. Based on the research results and the actual urban development in Inner Mongolia, the corresponding policy suggestions are put forward.
