武汉城市圈城乡文化整合的时空结构

Study on the spatial-temporal structure of the urban-rural cultural integration in Wuhan metropolitan circle

城镇化实践中的城乡文化建设失衡已引起世人关注,城乡文化整合已成为文化地理学关注的新领域。在简析武汉城市圈城乡文化的时空格局基础上,明确提出了城乡文化整合度的概念,并通过解析城乡文化整合时间维、城乡文化易感知人群、城乡文化信息流以及城乡文化最短传播路径,构建了城乡文化整合时空测度模型。综合运用熵权法、因子分析法和网络分析法,从县(市)域尺度上,探究了城镇化快速推进时期(1980-2010年)武汉城市圈城乡文化整合的时空结构和时空发展模式。研究表明:城乡文化整合的时空发展模式,即萌芽阶段的斑块式发展、形成阶段的波状式发展、聚散阶段的廊道式发展以及兴盛阶段的网络化发展,基本符合"点—轴"式区域社会经济扩展规律;也符合社会经济发展水平越高,城乡路网空间关联作用越强,城乡文化要素交流强度越大,城乡文化整合空间结构就更趋于完善的基本规律;城乡文化的空间结构发育程度还符合"核心区>受容区"的圈层分异规律。

The notion of urban-rural cultural integration(URCI) has become a new focus in cultural geography, given that the problem of the imbalance between urban and rural cultural development has raised great concern in the process of urbanization practice. The existing researches on URCI, however, are unable to effectively meet the application requirements of the integration of Chinese urban and rural culture, and also do not meet the internal demand for human geography discipline development. Taking Wuhan metropolitan circle as an example, this paper explicitly proposed the concept of integration degree of urban-rural culture based on a brief analysis of spatial- temporal pattern for urban- rural culture. Then, the spatial- temporal measure model of URCI was creatively constructed through analyzing the time dimension of URCI, the population who is sensitive to urban and rural culture, the cultural information flow between urban and rural areas, and the shortest path of cultural transmission from urban to rural area. On county/city scale, spatial-temporal structures and development patterns of URCI in the case area from 1980 to 2010 were explored, with the method of entropy, factor analysis and network analysis. The research demonstrated that:(1) spatial- temporal development patterns of URCI, namely, the plaque- type development in the embryonic stage, the wave- like development in the formative stage, the corridor-type development in the stage of diffusion and agglomeration and the network development in the prosperous stage, generally complied with the 'point-axis' theory of regional social and economic expansion;(2) they followed the basic law that the more the society and economy developed, the stronger the spatial correlation of the road network between urban and rural areaa was and the more cultural factors between urban and rural areaa flowed reciprocally, the more perfect the spatial structure of URCI became;(3)the development degree of spatial structure of urban-rural culture was also consistent with the rule of circle differentiation that the 'core area' is greater than 'reception ward'.
