共同守护那片蔚蓝(环球走笔)
Ren Min Ri Bao· 2025-11-11 22:40
在印度尼西亚北苏拉威西省附近海域,一场跨越国界的科学探索取得突破性进展。近期,中国与印尼的 科学家开展海洋生态联合调查,在这片海域发现了新的浅海热液口,成为两国携手应对气候变化、共同 守护海洋生态的生动实践。 热液口通常隐匿于数千米的深海,此次在浅海发现热液口实属罕见。更难得的是,在热液口高温、强酸 的极端环境下,周边依然存在多样性极高的珊瑚礁和海草床生态系统。这种奇特的生命现象,为全球气 候变化研究提供了宝贵的"天然实验室",中印尼科研团队能够通过观察研究典型海洋生态系统对气候变 化的适应与演变,进一步探索生态修复技术。 作为此次联合调查的中方负责人,我率领多学科团队与印尼专家们同心协力,克服暴雨、高温、毒蛇出 没等困难条件,共采集珊瑚、热液水体、浮游生物、环境DNA等样品500余份,获得了大量原位观测资 料。依托新发现的热液口与该海域原有的36个固定观测站位,一个功能更完备、数据更完善的中印尼北 苏拉威西海洋生态观测网络初步形成,将助力研究生物多样性和生态连通性的长期变化规律及响应机 制,为保护全球海洋生态系统、应对气候变化提供科学依据。 正如一位参与此次联合调查的印尼科学家所说,对海洋的守护是跨越国界的 ...
