湖泊不仅储水,也储碳。植物和藻类吸收的二氧化碳会随有机物沉入湖底,并在缺氧沉积物中保存数十年甚至更久。但当湖泊萎缩,原本被水覆盖的沉积物暴露在空气中,其中的有机质会加速分解,过去积累的碳可能重新返回大气。长期以来,干涸湖床造成的碳损失很少被纳入区域和全球碳清单。

    湖泊不仅储水,也储碳。植物和藻类吸收的二氧化碳会随有机物沉入湖底,并在缺氧沉积物中保存数十年甚至更久。但当湖泊萎缩,原本被水覆盖的沉积物暴露在空气中,其中的有机质会加速分解,过去积累的碳可能重新返回大气。长期以来,干涸湖床造成的碳损失很少被纳入区域和全球碳清单。

    湖泊不仅储水,也储碳。植物和藻类吸收的二氧化碳会随有机物沉入湖底,并在缺氧沉积物中保存数十年甚至更久。但当湖泊萎缩,原本被水覆盖的沉积物暴露在空气中,其中的有机质会加速分解,过去积累的碳可能重新返回大气。长期以来,干涸湖床造成的碳损失很少被纳入区域和全球碳清单。
    咸海曾是世界第4大湖泊。20世纪60年代以来,由于入湖河流被大量引向农业灌溉,其水域面积持续缩小,如今约90% 的湖面已经消失,原湖床变成大面积盐碱荒漠。以西班牙国家研究委员会布拉内斯高级研究中心(CEAB-CSIC)为首的国际团队发现,这场水资源与生态灾难还带来了一项长期被忽视的气候代价:咸海正由碳储存库转变为碳排放源。7月16日,相关研究发表于《Science》。
    研究团队于2022年对咸海开展野外考察,在不同干涸年代的湖床上采集沉积物岩芯并测量二氧化碳通量,同时结合卫星观测、植被生物量数据和无人机摄影测量,重建了咸海半个多世纪以来的碳变化。研究采用“以空间代时间”的方法,将暴露时间不同的湖床区域排列起来,从而推算沉积物在干涸后的持续失碳过程。
    结果显示,自1960年以来,暴露的咸海湖床已损失约2.04亿t碳,相当于向大气释放约7.48亿t二氧化碳。干涸湖床上重新生长的植被虽然能够吸收部分碳,但其抵消量不足总损失的1%。将这部分排放计入碳清单后,咸海盆地由原先估算的土地利用变化碳汇转变为净碳源。
    研究还发现,原湖床沉积物中仍保存着大量容易流失的有机碳。研究人员估算,若通过水资源管理恢复部分水面,使沉积物重新被水覆盖,可避免约1.65亿t碳继续释放,相当于约6.05亿t二氧化碳。水体覆盖能够限制沉积物与氧气接触,减缓有机质分解,使湖床重新发挥碳储存作用。
