摘要

滑坡灾害反映了人类社会与自然环境的冲突,对山区可持续发展提出了挑战。滑坡风险管理的主要任务是识别潜在滑坡,估计危险元素的破坏程度和潜在损失,并控制损失。抗灾能力被定义为一个社会系统应对灾害的综合能力,包括准备、预测、保存、吸收、应对、抵抗、恢复、减轻、学习和适应的能力。作为一个不可或缺的角色,抗灾能力使滑坡风险管理更加合理,以实现社会可持续性。然而,定量滑坡风险管理并没有充分重视恢复力的作用。因此,本文系统地讨论了恢复力在滑坡风险管理框架中的作用。定量滑坡风险管理框架包括危害分析、暴露分析、风险估计、风险评估和风险控制。在危险分析中,复原力评估有助于识别潜在的山体滑坡,这些滑坡可能因危险元素的复原力差而造成重大破坏。暴露分析中的复原力评估可能有助于确定某些滑坡最脆弱的因素或区域。在风险估计中考虑弹性有助于计算间接损失,并改进直接损失分析的结果。在风险评估中,抗灾能力作为一种灾害应对能力,会影响社会系统的滑坡风险承受阈值。增强复原力是减少社会系统脆弱性的一项重要战略。我们还提出,有效利用风险信息将提高滑坡恢复力评估的准确性。

The indispensable role of resilience in rational landslide risk management for social sustainability

Landslide disasters reflect the conflict between human society and the natural environment, posing challenges to the sustainable development of mountain regions. Identification of potential landslides, estimation of the degree of damage and potential losses of elements at risk, and control of the loss are the major tasks of landslide risk management. Resilience is defined as a social system’s comprehensive abilities to cope with disasters, including the abilities to prepare, anticipate, preserve, absorb, respond, resist, recover, mitigate, learn, and adapt. As an indispensable role, resilience enables more rational landslide risk management for social sustainability. However, quantitative landslide risk management does not pay sufficient attention to the role of resilience. Hence, in this paper, the role of resilience in a landslide risk management framework is systematically discussed. A quantitative landslide risk management framework consists of hazard analysis, exposure analysis, risk estimation, risk evaluation, and risk control. In hazard analysis, resilience assessment could help identify potential landslides that could cause significant damage due to the poor resilience of the elements at risk. Resilience assessment in exposure analysis might aid in identifying the most vulnerable elements or regions to certain landslides. Consideration of resilience in risk estimation aids in the calculation of indirect losses and improves the results of direct losses analysis. In risk evaluation, resilience as a disaster-coping ability will impact the social system's landslide risk tolerance threshold. Enhancing resilience is an essential strategy to reduce the vulnerability of social systems. We also proposed that the efficient use of risk information will increase the accuracy of landslide resilience assessments.

期刊介绍: Geography and Sustainability serves as a central hub for interdisciplinary research and education aimed at promoting sustainable development from an integrated geography perspective. By bridging natural and human sciences, the journal fosters broader analysis and innovative thinking on global and regional sustainability issues. Geography and Sustainability welcomes original, high-quality research articles, review articles, short communications, technical comments, perspective articles and editorials on the following themes: Geographical Processes: Interactions with and between water, soil, atmosphere and the biosphere and their spatio-temporal variations; Human-Environmental Systems: Interactions between humans and the environment, resilience of socio-ecological systems and vulnerability; Ecosystem Services and Human Wellbeing: Ecosystem structure, processes, services and their linkages with human wellbeing; Sustainable Development: Theory, practice and critical challenges in sustainable development.
