摘要:

为增强城市灾害韧性,从动态视角出发,研究中原城市群城市灾害韧性。首先,从基础设施韧性、经济韧性、社会韧性、生态韧性4个方面构建城市灾害韧性评价指标体系;其次,以熵值法计算各指标权重,应用综合指数法构建城市灾害韧性评价模型;最后,运用探索性空间数据分析(ESDA)、障碍度模型等方法揭示2003—2019年中原城市群城市灾害韧性水平的时空演变特征及障碍因子。结果表明:考察期内,中原城市群城市灾害韧性水平呈持续增长态势,呈现出显著的区域不平衡不协调现象,主要表现为中部高四周低的空间分布格局;从整体上看,城市灾害韧性度呈现空间正相关,空间集聚模式主要以高-高集聚和低-低集聚为主;障碍因子主要集中在经济和社会方面。

Abstract:

In order to enhance urban disaster resilience, this paper studied the urban disaster resilience of Zhongyuan urban agglomeration from a dynamic perspective. Firstly, the evaluation index system of urban disaster resilience was constructed from four aspects: infrastructure resilience, economic resilience, social resilience and ecological resilience. Secondly, the weight of each index was calculated by the entropy method, and the evaluation model was established by the comprehensive index method. Finally, ESDA and obstacle degree model were used to reveal the temporal and spatial differentiation characteristics and obstacle factors of urban disaster resilience in Zhongyuan urban Agglomeration from 2003 to 2019. The results show that during the study period, the urban disaster resilience level of Zhongyuan urban Agglomeration shows a sustained growth trend, showing an obvious regional imbalance and uncoordinated phenomenon, which is mainly manifested in the spatial distribution pattern of high in the central region and low around. On the whole, urban disaster resilience shows a positive spatial correlation, and the spatial agglomeration mode is mainly low-low agglomeration and high-high agglomeration. The obstacle factors were mainly focused on economic and social aspects.
