Based on statistical data and population flow data for 2016,and using entropy weight TOPSIS and the obstacle degree model,the centrality of cities in the Yangtze River Economic Belt(YREB)together with the factors influencing centrality were measured.In addition,data for the population flow were used to analyze the relationships between cities and to verify centrality.The results showed that:(1)The pattern of centrality conforms closely to the pole-axis theory and the central geography theory.Two axes,corresponding to the Yangtze River and the Shanghai-Kunming railway line,interconnect cities of different classes.On the whole,the downstream cities have higher centrality,well-defined gradients and better development of city infrastructure compared with cities in the middle and upper reaches.(2)The economic scale and size of the population play a fundamental role in the centrality of cities,and other factors reflect differences due to different city classes.For most of the coastal cities or the capital cities in the central and western regions,factors that require long-term development such as industrial facilities,consumption,research and education provide the main competitive advantages.For cities that are lagging behind in development,transportation facilities,construction of infrastructure and fixed asset investment have become the main methods to achieve development and enhance competitiveness.(3)The mobility of city populations has a significant correlation with the centrality score,the correlation coefficients for the relationships between population mobility and centrality are all greater than 0.86(P<0.01).The population flow is mainly between high-class cities,or high-class and low-class cities,reflecting the high centrality and huge radiating effects of high-class cities.Furthermore,the cities in the YREB are closely linked to Guangdong and Beijing,reflecting the dominant economic status of Guangdong with its geographical proximity to the YREB and Beijing's enormous influence as the national political and cultural center,respectively. 相似文献

城乡要素高速交互流动已成为影响现代乡村文化发展的新时空现象。立足重新认知并诠释多要素交互作用下中国乡土文化的新时代价值,聚焦城郊融合型村庄的公共文化空间多元形式与载体功能,以河南省舞阳县柴庄村为例,结合遥感影像与调查访谈结果,深度剖析其公共文化空间演变过程及驱动机制。结果显示：(1)柴庄村的公共文化空间经历了“村民自组织→政府主导→多元主体参与”的结构演变过程和“传统时期的供不适需→转型时期的以供适需→新时期的供需契合”的模式演变过程。(2)柴庄村的公共文化活动空间类型偏好与占比、村民的公共文化活动时间分配在城乡要素的交互作用下均发生了改变。(3)乡村公共文化空间演变是村民文化需求等内在需求力和政策、市场等外在供给力以及生活结构改变等潜在阻力共同作用的结果。立足中国城乡融合发展的宏观背景探讨乡村公共文化空间的演变及其机制既能拓展乡村文化地理学的研究对象与内容,也能更好地发挥地理学服务于乡村振兴的国家战略需求。 相似文献
