服务冬奥、支撑发展：冰冻圈科学的延拓

冰冻圈科学作为一门自然和人文深度交叉的新兴学科,其目的是认识自然规律,服务人类社会,促进可持续发展。近年来,中国冰冻圈研究实现了从传统基础研究到服务国家重大需求的跨越,这标志着学科的日臻成熟。北京冬奥会是我国重要历史节点的重大标志性活动。早在2016年冬奥会申办成功之初,当意识到国际顶级赛事对雪冰特殊需求“近在眼前”后,冰冻圈科学国家重点实验室即以国家自然科学基金创新研究群体项目（三期）和中国科学院学部院士咨询项目为依托,率先在河北张家口滑雪场开展了观测研究。过去5年来,冬奥雪务需求牵引着我国冰冻圈科学团队在雪冰物理关键技术环节上集中攻关,推动了学科向应用领域的延拓,取得了预期成果。文章总结研究团队研发的冬奥雪务保障关键技术,展望我国冰雪产业发展路径,从战略思维、科学积淀及实践创新的角度阐述冰冻圈科学的应用及拓展,提出了相关思考和建议。

Serving Beijing 2022 Olympic Winter Games and Developing Ice and Snow Industry: Application and Extension of Cryospheric Science

Cryospheric Science, as an emerging interdisciplinary research field combining natural science and humanity, aims to understand nature''s law, serve human society and promote sustainable development. In recent years, by deepening the understanding of the cryosphere elements and the whole sphere, and by expanding the application research of cryospheric science, the Chinese community of cryospheric science has developed by leaps and bounds and realized the crossover from the traditional basic research to serving the major national needs, which marks the increasing maturity of the discipline. The Beijing 2022 Olympic Winter Games is a major landmark event at an important historical time in China. The special need of using snow and ice as the sports interface has led China''s cryosphere scientific team to focus on tackling key technical links of icy snow physics since 2016, and promoted the development of China''s cryosphere scientific application research in the past five years. In view of the key technology of snow service for the Beijing 2022 Olympic Winter Games and the national needs of ice and snow economic development, a research team was formed by the State Key Laboratory of Cryospheric Science, in cooperation with scientific institutions (such as Beijing Normal University, Chinese Academy of Meteorological Sciences, and Harbin Sport University) and first-class enterprises in the domestic ice and snow industry (such as Yabuli Sports Training Base, National Alpine Skiing Centre, and Genting Snow Park). The team has solved many technical problems, including snow making, icy snow track making, snow quality prediction and snow storage. The team studied the impact of climate change on China''s ski tourism and how ice and snow tourism can help with the sustainable development of mountainous regions economy. It also trained the first batch of graduate students and core technicians of ski resorts in China. This paper summarizes the key snow-making technology of the Beijing 2022 Olympic Winter Games, and projects the development path of China''s ice and snow industry. It expounds the application and expansion of cryospheric science from the perspective of strategic thinking, knowledge building and practical innovation, and puts forward relevant thoughts and suggestions.
