在青藏高原中部一个以多年冻土为主的盆地（北流河盆地）监测了不同的水体，包括降水、温带湖泊/池塘、溪流、天然泉水以及地冰。从 2017 年到 2022 年，在该冻土盆地连续进行了六年的采样工作。在六年的连续采样工作中，共采集了 554 个降水样本、2402 个湖泊/池塘样本、675 个溪流水样本、102 个上冻土层水样本和 19 个亚冻土层水样本。重要的是，从 17 个钻孔中采集了 355 个地冰样本，从 2 个解冻坍塌剖面中采集了 4 个样本。获得了稳定同位素（δ18О、δD 和 d-过量）。这是青藏高原冻土区的第一个综合数据集，有助于了解亚洲水塔冻土退化下的水文过程。", "ds_source": "

Different water bodies, including precipitation, temperate lakes/ponds, streams, natural springs, and ground ice, were monitored in a basin dominated by permafrost in the central part of the Qinghai Tibet Plateau (Beiliuhe Basin). From 2017 to 2022, six consecutive years of sampling work were conducted in this permafrost basin. In six years of continuous sampling work, a total of 554 precipitation samples, 2402 lake/pond samples, 675 stream water samples, 102 upper frozen soil layer water samples, and 19 sub frozen soil layer water samples were collected. Importantly, 355 ground ice samples were collected from 17 boreholes and 4 samples were collected from 2 thawing collapse profiles. Obtained stable isotopes (δ 18 О, δ D, and d-excess). This is the first comprehensive dataset of permafrost regions on the Qinghai Tibet Plateau, which helps to understand hydrological processes under permafrost degradation in Asian water towers.
