Climate and environmental changes associated with anthropogenic global warming are being increasingly identified in the European Alps, as seen by changes in long-term high-alpine temperature, precipitation, glacier cover and permafrost. In turn, these changes impact on land-surface stability, and lead to increased frequency and magnitude of natural mountain hazards, including rock falls, debris flows, landslides, avalanches and floods. These hazards also impact on infrastructure, and socio-economic and cultural activities in mountain regions. This paper presents two case studies (2003 heatwave, 2005 floods) that demonstrate some of the interlinkages between physical processes and human activity in climatically sensitive alpine regions that are responding to ongoing climate change. Based on this evidence, we outline future implications of climate change on mountain environments and its impact on hazards and hazard management in paraglacial mountain systems.
与人为全球变暖相关的气候和环境变化在阿尔卑斯山地区日益明显,这表现在高山地区长期温度、降水、冰川覆盖和永久冻土的变化上。反过来,这些变化又影响到地面的稳定性,导致自然山地灾害的频率和规模增加,包括岩石崩塌、泥石流、滑坡、雪崩和洪水。这些灾害还影响到山区的基础设施以及社会经济和文化活动。本文介绍了两个案例研究(2003 年热浪、2005 年洪水),这些研究展示了在应对持续气候变化的气候敏感高山地区,物理过程和人类活动之间的一些相互关系。基于这一证据,我们概述了气候变化对山地环境的未来影响及其对山前系统灾害和灾害管理的影响。
