北极正在迅速变暖，对下面的永久冻土构成重大威胁。永久冻土退化已经对北极的基础设施造成了广泛的破坏，使社区和工业处于危险之中。预计气候变暖将进一步降低永久冻土支持基础设施的能力，因此需要重新思考未来永久冻土地区的建设和发展。本文重点介绍了三个北极地区的人口和基础设施的永久冻土：美国（阿拉斯加），加拿大和俄罗斯。对这三个地区的冻土施工实践进行了研究，以确定最佳做法和主要差距。我们确定缺乏标准化，编纂的施工指导方针;在社区中缺乏冻土岩土监测;将气候情景纳入未来规划的障碍;有限的数据共享;以及多年冻土专业人员数量少，这是限制该地区在气候变化面前恢复力的主要制约因素。完善建筑实践和标准，实施可操作的永久冻土监测系统，制定缩小规模的气候预测，并整合当地知识，将在快速变暖的气候条件下最大限度地减少永久冻土退化的影响。
The Arctic is rapidly warming posing a significant threat to underlying permafrost. Permafrost degradation has already resulted in extensive damage to the Arctic’s built infrastructure, putting communities and industries at risk. Projected climate warming will further reduce the capacity of permafrost to support infrastructure, thereby requiring a rethinking of construction and development of permafrost regions in the future. This paper focuses on three Arctic regions with a substantial presence of population and infrastructure on permafrost: USA (Alaska), Canada, and Russia. The three regions’ permafrost construction practices are examined in order to identify best practices and major gaps. We identify a lack of standardized, codified construction guidelines; an absence of permafrost-geotechnical monitoring in communities; barriers to integrating climate scenarios into future planning; limited data sharing; and low numbers of permafrost professionals as major constraints limiting the region’s resilience in the face of climate change. Refining building practices and standards, implementing operational permafrost monitoring systems, developing downscaled climate projections, and integrating local knowledge will minimize the impacts of permafrost degradation under rapidly warming climatic conditions.
