摘要

自然灾害和人为灾害正威胁着世界各地的城市。城市的抗灾能力在灾害风险应对和灾后恢复中发挥着至关重要的作用。在山区城市,山体滑坡是最频繁和最具破坏性的灾害之一。本研究提出了一个新颖的方法框架,用于评估山区城市的空间抗灾能力,特别是对山体滑坡的抗灾能力。本研究以三峡库区的重庆为重点,从概念上将山区城市对滑坡的抗灾能力分为两个维度:环境抗灾能力和社会抗灾能力。本研究通过汇编 4464 起历史滑坡事件的数据,建立了一个综合数据库,其中包含 17 个环境复原力指标和 16 个社会复原力指标。采用随机森林(RF)模型评估环境复原力,AUC 高达 0.968,准确率为 97.1%。社会复原力采用层次分析法(AHP)进行评估,综合复原力采用与理想解决方案相似度排序法(TOPSIS)进行排序。主要结论包括(1) 建立多维复原力指标体系,有效评估山区城市以滑坡为导向的复原力。(2) 山区城市的综合复原力呈现出明显的空间集群模式。环境复原力较低的地区主要表现为降雨量大、地形复杂。社会复原力较高的地区集中在城市中心,而外围地区则因经济实力较弱、医疗基础设施不足而面临挑战。(3) 山区城市的未来发展应采取全面、可持续的战略,平衡环境复原力与社会复原力之间的关系。本研究为山区城市的防灾和抗灾能力评估提供了一个强有力的框架,可用于评估其他山区城市的抗灾能力。

Landslide-oriented disaster resilience evaluation in mountainous cities: A case study in Chongqing, China
Natural and human-made disasters are threatening cities around the world. The resilience of cities plays a critical role in disaster risk response and post-disaster recovery. In mountainous cities, landslides are among the most frequent and destructive hazards. This study presents a novel methodological framework for assessing the spatial resilience of mountainous cities specifically against landslides. Focusing on Chongqing in the Three Gorges Reservoir region, this study conceptually divides the disaster resilience of mountain cities to landslides into two dimensions: environmental resilience and social resilience. This study developed a comprehensive database by compiling data from 4,464 historical landslide events, incorporating 17 environmental resilience indicators and 16 social resilience indicators. Random forest (RF) model was employed to evaluate environmental resilience, achieving a high AUC of 0.968 and an accuracy of 97.1 %. Social resilience was assessed by the Analytic Hierarchy Process (AHP), and comprehensive resilience was ranked by the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Key findings include: (1) Establishing a multi-dimensional resilience indicator system that effectively assesses landslide-oriented resilience in mountainous cities. (2) Comprehensive resilience in mountainous cities exhibit distinct spatial clustering patterns. Regions with lower environmental resilience are mainly characterized by high rainfall and complex terrain. higher social resilience concentrated in city centers, while peripheral regions face challenges due to weaker economies and inadequate healthcare infrastructure. (3) In the future development of mountain cities, comprehensive and sustainable strategies should be adopted to balance the relationship between environmental resilience and social resilience. This study provides a robust framework for disaster prevention and resilience assessment in mountainous cities, which can be applied to evaluate the disaster resistance capabilities of other mountainous cities.
