In recent years, Chinese scientists have launched an innovative experiment on the Dagula Glacier in Sichuan Province—covering parts of the glacier with a ‘blanket’ to slow its accelerated melting caused by climate change. The core of this approach involves laying a special insulating material, such as white geotextile fabric, over the glacier’s surface to reflect solar radiation and reduce heat absorption, thereby decreasing melt rates. Since 2020, researchers from the Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, together with local teams, have covered approximately 500 square meters of the glacier and continuously monitored its effectiveness. Preliminary results show that ice melt in the covered areas has been reduced by more than 50% compared to uncovered sections.This method draws inspiration from similar practices in the Alps but has been adapted to suit China’s high-altitude, high-UV environment. Scientists emphasize that ‘blanketing’ glaciers is not a permanent fix but a temporary adaptive measure aimed at buying time for glacial conservation. Meanwhile, the experiment provides valuable data for understanding glacier dynamics and evaluating the impact of human interventions. In the long term, curbing global warming and reducing greenhouse gas emissions remain the fundamental solutions to protect glaciers worldwide.
近年来，中国科学家在四川达古冰川开展了一项创新性实验——为冰川“盖被子”，以减缓其因气候变暖而加速消融的趋势。这项措施的核心是在冰川表面覆盖一层特殊的隔热材料（如白色土工布），通过反射太阳辐射、降低热量吸收，从而减少冰川的融化速度。2020年起，中国科学院西北生态环境资源研究院联合当地科研团队，在达古冰川选定区域铺设了约500平方米的隔热材料，并持续监测其效果。初步数据显示，覆盖区域的冰川消融速度比未覆盖区域降低了50%以上。这一做法借鉴了阿尔卑斯山等地的类似实践，但在中国高海拔、强紫外线的特殊环境下进行了本地化改良。科学家强调，“盖被子”并非永久解决方案，而是应对气候变化影响的临时适应性措施，旨在为冰川保护争取时间。同时，该实验也为研究冰川动态、评估人工干预效果提供了宝贵数据。长远来看，遏制全球变暖、减少温室气体排放仍是保护冰川的根本途径。
