摘要
基于改进的"压力—状态—响应"研究框架、组合权重模型、Dagum基尼系数对京津冀城市群2001-2020年的城市韧性时序演变特征及其空间差异进行实证研究.结果表明:①时序演变上,京津冀城市群城市韧性水平在研究区间内总体呈波动式上升的趋势,存在明显的阶梯式失衡现象;②空间分布上,京津冀城市群高韧性区域由点到面、由中部至南北部进行蔓延,总体呈现"北京—天津双核驱动,中北强南弱"的韧性格局;③区域差异来源上,京津冀城市群城市韧性区域间不均衡现象突出而区域内发展较为均衡,区域间差异是京津冀城市群城市韧性总体差异的主要来源.
Abstract
This paper analyzed and discussed the temporal evolution and spatial differences of urban resilience in the Beijing-Tianjin-Hebei urban agglomeration from 2001 to 2020 using the improved pressure-state-response(PSR)research framework,the combined weight model,and Dagum's Gini coefficient.The results showed that:①In terms of temporal evolution,the resilience level of each city in the Beijing-Tianjin-Hebei city agglomeration exhibited a fluctuating upward trend during the study period.Beijing showed the most significant increase in resilience level,followed by Tianjin.Most cities in Hebei also exhibited a fluctuating upward trend,with Shijiazhuang and Langfang having the highest average annual resilience growth rates in the province.②In terms of the spatial pattern,the high resilience areas in the Beijing-Tianjin-Hebei urban agglomeration expanded from the central part of the city to the south and north,indicating a spreading pattern from the point to the surface.The overall resilience pattern showed a trend of"Beijing-Tianjin dual-core drive,with a strong resilience in the center-north region and a relatively weaker resilience in the south".③In terms of regional sources of variation,the urban resilience of the Beijing-Tianjin-Hebei urban agglomeration exhibited significant in-ter-regional imbalances.However,intra-regional development remained relatively balanced,and the primary factor contributing to the overall resilience differences in the agglomeration was the presence of inter-regional disparities.
