摘要
城市韧性与人口分布之间的相互作用对贵州高原城市可持续发展具有重要意义,以贵州省各市州为研究对象,综合运用熵值法、耦合协调度模型、灰色关联度模型,分析2012—2021年贵州高原城市韧性与人口分布的时空演变格局,揭示两者间的关联性,并对影响两者耦合协调的因素进行研究。结果表明:(1)从时间上看,2012—2019年贵州高原城市韧性呈现出上升趋势,2019—2021年由于受新冠疫情冲击的影响出现小幅度下降趋势,空间上呈现出同心圆状自内向外逐渐递减的态势。(2)人口主要集中分布在贵阳市、安顺市、六盘水市以及毕节市,空间上呈现出自西北向东南逐渐递减的态势。(3)贵州高原城市韧性与人口分布的整体耦合协调水平不高,仅贵阳市处于优质协调状态,大部分市州处于初级协调状态,空间上呈现出自西北向东南递减的态势。(4)两系统间耦合协调度的空间差异演变主要是受经济发展水平、产业结构以及政府调控能力等9个因素相互作用的影响。
The interaction between the urban resilience and the population distribution is of great significance to the sustainable development of cities on the Guizhou plateau.Taking the cities and prefectures in Guizhou province as the research objects,this paper employs the entropy method,the coupling coordination degree model,and the grey correlation degree model to comprehensively analyze the spatio-temporal evolution pattern of urban resilience and population distribution in cities on the Guizhou plateau from 2012 to 2021,reveals the correlation between them,and studies the factors affecting their coupling coordination.Results show as follows.(1)The urban resilience of the Guizhou plateau showed an upward trend from 2012 to 2019,and showed a small downward trend from 2019 to 2021 due to the impact of the COVID-19 epidemic.(2)The population is mainly concentrated in Guiyang,Anshun,Liupanshui and Bijie,showing a decreasing trend from the northwest to the southeast in space.(3)The overall coupling coordination level of urban resilience and population distribution on the Guizhou plateau is not high,only Guiyang is in a high-quality coordination state,and most cities and counties are in a barely coordinated state,showing a decreasing trend from the northwest to the southeast.(4)The spatial difference of coupling coordination degree between these two systems is mainly affected by the interaction of some factors,such as economic development level,industrial structure and government regulation ability.
