中部地区资源型城市质量与规模时空差异演化研究——以山西省为例

在“新常态”背景下,山西省作为全国能源重化工基地,其城市面临转型与发展双重压力。通过构建指标测评体系,运用熵值法与协调模型等方法对山西省11个地级市城市质量年均增长率和城市规模年均增长率间协调发展程度的时空格局进行了相关分析。研究表明：1）山西省整体城市规模变异系数较大,而城市质量变异系数较小;且山西省各地级市城市质量、城市规模及其城市综合发展水平时空差异变化明显,在空间上由北向南总体呈“W”型分布格局。2）山西省各地级市在2005—2010年与2010—2014年两个时间序列上,城市质量年均增长率与城市规模年均增长率间的对比关系不确定,即存在城市质量发展速率超过城市规模或城市质量发展速度滞后于城市规模的现象。3）山西省各地级市城市质量年均增长率与城市规模年均增长率间协调发展关系存在着明显的地域空间分异,且在不同时间序列上形成了不同的城市发展主导类型,需因地制宜地分类指导其城市建设。

Research on Spatial and Temporal Evolution of Quality and Scale of Resource Based Cities in Central Region of China: A Case Study of Shanxi Province

Shanxi Province, as a national base of energy resources and heavy chemical industry, its cities were confronted with dual pressure from transformation and development under the “new normal” background. By constructing the evaluation index system, the spatial and temporal patterns of the coordination relation between average annual growth rate of urban quality and urban scale of 11 prefecture-level cities in Shanxi Province were studied with the entropy method and coordination model. The result showed that: 1) The variation coefficient of urban scale was big, while the variation coefficient of urban quality was small; the spatial and temporal variations of urban quality, urban scale and comprehensive development level of prefecture-level cities were obvious and presented a “W” pattern from north to south. 2) There was an ambiguous relationship between the average annual growth rate of urban quality and the average annual growth rate of urban scale during the periods of 2005-2010 and 2010-2014, and there were two kinds of phenomena that the growth rate of urban quality was lower than the growth rate of urban scale and that the growth rate of urban quality was higher than the growth rate of urban scale. 3) The coordination relationship between the development of urban quality and urban scale presented obvious spatial variation, which resulted in different dominant styles of urban development in different periods. Therefore, urban development should be performed according to local conditions.
