摘要
以2011—2021年中原城市群29个地级市为研究对象,从经济韧性、社会韧性、生态韧性、基础设施韧性和制度韧性5个维度构建城市韧性评价指标体系;运用组合赋权-TOPSIS方法对中原城市群的城市韧性水平进行评估,并对其影响城市韧性发展的障碍因子进行研究.结果显示:(1)中原城市群城市韧性整体呈现上升态势,城市间韧性发展水平存在差异,但差距逐年缩小.(2)分维度的韧性水平呈现显著差异,生态韧性水平最高,基础设施韧性次之,随后是经济韧性、社会韧性和制度韧性.(3)中原城市群城市韧性水平呈现出以郑州为核心,西北部区域较高,东南部区域较低的空间分布特征.(4)阻碍中原城市群城市韧性水平的主要因素为经济韧性和社会韧性,且障碍度有逐渐增大的趋势.
Taking 29 prefecture-level cities in the Central Plains Urban Agglomeration from 2011 to 2021 as the research object,the evaluation index system of urban resilience was constructed from five dimensions:economic resilience,social resilience,ecological resilience,infrastructure resilience and institutional resilience.The combined weighting-TOPSIS method was used to evaluate the urban resilience level of the Central Plains Urban Agglomeration,and the obstacle factors affecting the development of urban resilience were studied.The findings are as follows:(1)The overall urban resilience of the Central Plains Urban Agglomeration has shown an upward trend,and there are differences in the level of resilience development among cities,but the gap is narrowing year by year.(2) Resilience levels differ significantly across the five dimensions,with ecological resilience ranking highest,followed by infrastructure resilience,economic resilience,social resilience,and institutional resilience.(3)Spatially,the level of urban resilience in the Central Plains Urban Agglomeration is characterized by a core centered around Zhengzhou,with higher resilience levels in the northwest and lower resilience levels in the southeast.(4)The main factors that hinder the level of urban resilience in the Central Plains Urban Agglomeration are economic resilience and social resilience,and the obstacle degree has a gradually increasing trend.
