在青藏高原记录地球大气变化 在青藏高原海拔3816米的瓦里关山顶，欧亚大陆腹地唯一的大陆型全球大气本底站——瓦里关全球大气 本底站已连续运行30多年。这里产生的长期序列观测数据及"瓦里关曲线"，被持续纳入世界气象组织温 室气体公报，成为刻画全球气候变化趋势的重要科学依据。 2025年9月，习近平主席在联合国气候变化峰会上发表视频致辞时强调，应对气候变化是一项紧迫而长 期的任务。让我们积极行动起来，推动实现人与自然和谐共生的美好愿景，守护好我们共同的地球家 园！ 立高原、望全球，观风云、惠世界。2026年2月1日起，《青海省瓦里关全球大气本底站保护若干规定》 将正式施行，这意味着，瓦里关站的科学价值获得了地方法规层面的系统保障。从填补观测空白到记录 绿色低碳转型之路，在高山之巅，瓦里关站见证了我国参与全球气候治理的主动担当。 这是瓦里 依托30多年不间断观测，瓦里关站积累了连续、长期的大气二氧化碳浓度观测数据。据此绘制而成的变 化曲线——"瓦里关曲线"，反映了大气二氧化碳月平均浓度的长期变化，与美国夏威夷冒纳罗亚全球大 气本底站的观测结果高度一致。 两处全球大气本底站，一个代表欧亚大陆腹地，一个代表太平洋海洋型 ...
