2025年12月21日10:00至17:00，中国科学院大学国际学院携手公益环保组织“手护自然”，在北京“京西古道”成功举办“徒步清山”公益环保活动。本次活动以“手护自然，行走守护”为主题，以国际学生为主要参与群体，旨在引导来自不同国家和文化背景的学生走进自然、理解生态保护的重要性，并通过身体力行的方式参与环境治理，推动可持续发展理念的实践与传播。

From 10:00 a.m. to 5:00 p.m. on December 21, 2025, the International College of the University of Chinese Academy of Sciences (UCAS), in collaboration with the environmental nonprofit organization Nature Guard, successfully organized an environmental hiking and clean-up activity along the Jingxi Ancient Trail in Beijing. With international students as the primary participants, the event, themed “Protecting Nature Through Action,” aimed to engage students from diverse cultural backgrounds in hands-on environmental protection and promote the practical application of sustainable development concepts.

 本次活动共有56名志愿者参加，其中国际学生占较大比例。全体志愿者沿京西古道徒步11.36公里，累计爬升165米，共清理各类垃圾21.87公斤。国际学生在活动中积极投入，与中国志愿者密切协作，以实际行动为自然环境减负，展现了青年群体对公共事务与生态保护的高度责任感。

A total of 56 volunteers participated in the activity, with international students making up a significant proportion of the group. The volunteers completed an 11.36-kilometer hike with a cumulative elevation gain of 165 meters, collecting 21.87 kilograms of waste along the trail. International students actively engaged throughout the activity, working closely with their Chinese volunteers and demonstrating a strong sense of environmental and social responsibility.

  活动当天，国际学生与中国志愿者一同乘坐大巴前往京西古道。在行程中，“手护自然”组织的志愿者为同学们系统讲解了环境保护的基本理念，包括野外垃圾对生态系统的影响、“无痕山林”原则，以及个人在自然环境中应承担的环保责任，同时介绍了徒步活动的安全注意事项，帮助国际学生更好地了解中国户外环保实践。

On the day of the event, international and Chinese volunteers traveled together by bus to the Jingxi Ancient Trail. During the journey, volunteers from Nature Guard delivered informative presentations on environmental protection, including the ecological impact of litter, the principles of “Leave No Trace,” and individual responsibilities in natural environments. Safety guidelines were also provided to help international students better understand outdoor environmental practices in China.

 抵达目的地后，志愿者们在工作人员的组织下有序分组，领取环保垃圾袋和防护手套，并在中国志愿者的带领下开展徒步清山行动。对许多国际学生而言，京西古道不仅是一处自然景观，更是一次深入了解中国历史、人文与生态环境的难得体验。

Upon arrival, participants were organized into groups and provided with environmentally friendly garbage bags and protective gloves. Guided by Chinese volunteers, the clean-up hike began along designated routes. For many international students, the Jingxi Ancient Trail was not only a natural site but also a valuable opportunity to experience China’s history, culture, and ecological landscape firsthand.

 在徒步过程中，国际学生一边欣赏沿途山林景色，一边认真清理散落在古道及周边区域的塑料制品和食品包装等垃圾。大家相互协作、彼此提醒，让环保理念在跨文化合作中转化为具体而可见的行动。

During the hike, international worked side by side, collecting plastic waste, food packaging, and other litter while enjoying the surrounding natural scenery. Through close collaboration and mutual support, environmental awareness was translated into concrete action across cultures.

 本次活动不仅是一项环保实践，更是一项具有鲜明国际特色的社会参与活动。国际学生通过亲身参与中国的环保公益行动，加深了对中国生态文明理念的理解，也在实践中体会到环境保护作为全球议题所具有的共同价值和现实意义。

This activity was not only an environmental initiative but also a form of social engagement with a strong international dimension. By participating in environmental protection efforts in China, international students deepened their understanding of China’s approach to ecological conservation and experienced firsthand the shared global values underlying environmental protection.

 未来，中国科学院大学国际学院将继续以国际学生为重要主体，深化与公益组织的合作，推动更多融合社会实践与可持续发展理念的活动，助力国际学生在中国学习期间提升社会责任意识，成长为具有全球视野和行动力的青年力量。

Looking ahead, the International College of UCAS will continue to place international students at the center of its social practice initiatives, strengthening cooperation with public welfare organizations and promoting activities related to sustainability and social responsibility. Through these efforts, the College aims to support international students in developing global perspectives and becoming active contributors to a sustainable future.
