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, thermokarst lakes/ponds, stream, natural springs, as well as ground ice were monitored in a permafrost-dominated Basin (the Beiluhe basin) on central Qinghai-Tibet Plateau (QTP). Six years’ continuous sampling work were conducted between 2017 and 2022 in this permafrost basin. Totally, 554 precipitation samples, 2402 lakes/ponds samples, 675 stream water samples, 102 supra-permafrost water samples, and 19 sub-permafrost water samples were collected during six years’ continuous sampling work. Importantly, 355 ground ice samples were collected from 17 boreholes and 4 samples were obtained from 2 thaw slump profiles. The stable isotopes (δ18О, δD, and d-excess) were obtained. This is the first comprehensive dataset in permafrost regions on the QTP, which will facilitate the understanding of hydrological processes under permafrost degradation in the Asian water Tower.
