山脉是我们世界的重要淡水来源，但它们在全球水资源中的作用很可能会因气候变化而发生重大变化。我们今天对这些潜在变化的了解程度如何？对水资源管理、气候变化适应和不断演变的水政策有何影响？为了回答上述问题，我们考察了11个案例研究区域，目的是提供全球概况，找出研究差距，并制定研究、管理和政策建议。在设定了案例研究区域的水资源压力、水管理能力和科学能力后，我们从高地-低地的角度考察水资源知识状况，一方面关注山区，另一方面关注邻近的低地地区。在此基础上，确定了研究重点，包括降水、雪水当量、土壤参数、蒸散和升华、地下水以及增强的变暖和反馈机制。此外，还强调了在高海拔地区进行环境监测的重要性。然后，我们提出了如何在研究、水资源管理和政策领域，以及通过这些领域之间更好的互动，在气候变化下的山区水资源管理方面取得进展的建议。我们的结论是，山区水资源的有效管理迫切需要更详细的区域研究和更可靠的情景预测，而且必须通过联系相关学科来提高山区水资源研究的综合性。此外，管理者和研究人员之间的知识交流必须得到改善，并以长期持续互动为导向。
Mountains are essential sources of freshwater for our world, but their role in global water resources could well be significantly altered by climate change. How well do we understand these potential changes today, and what are implications for water resources management, climate change adaptation, and evolving water policy? To answer above questions, we have examined 11 case study regions with the goal of providing a global overview, identifying research gaps and formulating recommendations for research, management and policy.After setting the scene regarding water stress, water management capacity and scientific capacity in our case study regions, we examine the state of knowledge in water resources from a highland-lowland viewpoint, focusing on mountain areas on the one hand and the adjacent lowland areas on the other hand. Based on this review, research priorities are identified, including precipitation, snow water equivalent, soil parameters, evapotranspiration and sublimation, groundwater as well as enhanced warming and feedback mechanisms. In addition, the importance of environmental monitoring at high altitudes is highlighted. We then make recommendations how advancements in the management of mountain water resources under climate change could be achieved in the fields of research, water resources management and policy as well as through better interaction between these fields.We conclude that effective management of mountain water resources urgently requires more detailed regional studies and more reliable scenario projections, and that research on mountain water resources must become more integrative by linking relevant disciplines. In addition, the knowledge exchange between managers and researchers must be improved and oriented towards long-term continuous interaction.
