京津冀城市群城市韧性时空演变特征及空间差异研究OA北大核心CHSSCDCSTPCD

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.
