川南城市群城镇化水平综合分析!

Comprehensive Analysis of Urbanization Level of Urban Agglomeration of South Sichuan

以川南城市群39个县(区)为研究区,从传统城镇化水平、产业结构水平、居民经济实力、教育文化、基础设施5个方面选取13项指标,构建城镇化水平综合测度指标体系.利用主成分分析对2015年川南城市群城镇化水平进行综合测度,获得城镇化水平综合得分,并利用GIS制图技术和反距离权重插值法,绘制川南城市群城镇化水平等级图与空间扩展差异图.结果表明:研究区城镇化水平整体低下,近2/3的区县低于其平均水平,综合得分最高值为56.914,最小值为-20.158,区域城镇化水平差异显著;空间分布差异明显,水平较高区县主要分布于中部和北部,水平较低的地区主要分布在研究区南部;城镇化发展水平高的地区,其空间扩展能力越强.通过对川南城市群城镇化水平的综合分析,为该地区城镇化发展提供决策依据.

Taking 39 counties(or districts)of southern urban agglomerations as the research area,13 indicators were selected from the following five aspects:the level of traditional urbanization,the level of industrial structure,the economic strength of residents,education and culture,and infrastructure,and an indicator system for comprehensive analysis of the level of urbanization was constructed.Principal component analysis was used to give a comprehensive analysis of the urbanization level of urban clusters in South Sichuan in 2015,and a comprehensive score of urbanization level was obtained,then the difference map of urbanization level and spatial expansion in Southern Sichuan Urban Agglomeration was drawn by GIS mapping technology and inverse distance weight method.The results show that the urbanization level of the studied area is generally low,with nearly 2/3 of the districts and counties lower than the average level.The maximum value of the comprehensive score was 56.914,and the minimum value was 20.158,indicating a rather significant difference in urbanization level.The spatial distribution difference is obvious.The higher level districts and counties are mainly distributed in the middle and north,the lower level districts are mainly distributed in the south of the studied area.The area with high level of urbanization development has stronger spatial expansion capability.Through a comprehensive analysis of the urbanization level of the urban clusters in south Sichuan,this paper provides with the decision-making basis for urbanization development in the region.
