武陵山片区品位城市建设时空变化

Temporal and Spatial Variation of Grade City Construction in Wuling Mountain Area

以武陵山片区6个中心城市为研究对象,构建了由经济、社会、文化、环境4类品位因子及24个指标组成的品位城市建设评价指标体系,利用熵权法确定指标权重,运用TOPSIS法和GIS软件分析品位城市建设时空演变.结果表明,6个中心城市的品位城市建设平均贴近度从高到低依次为吉首市、恩施市、铜仁市、怀化市、黔江区、张家界市;时间维度上,2010年、2015年和2019年恩施市、怀化市的城市品位逐年下滑,张家界市、吉首市和黔江区的变化较小,铜仁市提升较大;空间维度上,经济、社会、文化和环境品位格局略有差异,整体分布格局由“中部高,两翼低”转向“西北高,东南低”,最终变为“中部高,南北低”.为了促进武陵山片区城市高质量发展,提升城市品位,从经济建设、社会设施、文化实力和生态环境4个方面对品位城市建设提出了建议.

This paper takes the six central cities in Wuling Mountain Area as the research object,constructs the evaluation index system of grade city construction consisting of four grade factors including economy,society,culture and environment and 24 indexes,determines the index weight by entropy weight method,and analyzes the temporal and spatial evolution of grade city construction by TOPSIS and GIS.The results show that in the urban construction of the six central cities in Wuling Mountain Area,the average closeness degree from high to low is:Jishou City,Enshi City,Tongren City,Huaihua City,Qianjiang District,Zhangjiajie City.In terms of time dimension,the urban grade of Enshi City and Huaihua City decreased year by year,while the change of Zhangjiajie City,Jishou City and Qianjiang District was small,and Tongren City improved greatly.In terms of spatial dimension,the pattern of economic,social,cultural and environmental grade is slightly different,and the development pattern of different grade factors is different.The overall grade changes from"high in the central part,low in the two wings"to"high in the northwest,low in the southeast",and finally forms a development pattern of"high in the central part,low in the north and south".Finally,in order to promote the high quality development of the city in Wuling Mountain Area and improve the city grade,the paper puts forward suggestions from four aspects:economic construction,social facilities,cultural strength and ecological environment.
