重庆城乡关联发展的空间演变分析及综合评价

SPATIAL EVOLUTION OF CHONGQING URBAN-RURAL INTERACTION AND ITS COMPREHENSIVE EVALUATION

本文在系统分析影响城乡关联发展的几类因素的基础上 ,利用重庆直辖前后不同年份的数据资料 ,运用因子分析技术提取影响城乡关联发展的主导因子 ,并利用ArcGIS将主因子信息空间化 ,借以直观的对比不同时间城乡发展的空间变化 ,揭示影响城乡关联变化的主要驱动因素。得到的主要结论是 :影响重庆城乡关联变化的三大因子是城乡产业结构因子、城乡交流因子以及城镇规模因子。重庆城乡关联变化的特点是重庆都市圈发展稳定 ,一直处于一级中心的地位 ;空间分布特点是圈层性日益突出 ;包括基础设施在内的硬环境改善相对其他因子的改善更为突出。

Based on the statistics of Chongqing in 1996 and 2001,which represent the years before and after Chongqing became a municipality of China, methods of factor analysis and spatial analysis are used to analyze the urban-rural interaction of Chongqing and its comprehensive evaluation. The three main factors of urban-rural interacting development include: urban-rural industry structure, urban-rural intercommunion and town scale. Then the authors use ArcGIS to spatialize the main factors in order to contrast the changes of the two years directly. The characteristic of urban-rural interaction in Chongqing can be summarized as follows. ①the urban-rural interaction of Chongqing metropolitan area is steady. It is always in the first center.②The characteristic of spatial circle structure is more and more outstanding. ③Compared to other factors, the change of infrastructure is more insignificant. Finally, the authors consider that the institution innovation is the main driving force of urban-rural interaction in Chongqing by comprehensive evaluation.
