限制过去水文变化的幅度可能会改善对未来水资源可获得性变化的理解和预测。在这里，我们证明了地下水位深度，一个敏感的水气候指标，可以用地下水中的Kr和Xe同位素定量重建。我们首次对地下水中这些溶解的稀有气体同位素进行了高精度的测量(
Constraining the magnitude of past hydrological change may improve understanding and predictions of future shifts in water availability. Here we demonstrate that water-table depth, a sensitive indicator of hydroclimate, can be quantitatively reconstructed using Kr and Xe isotopes in groundwater. We present the first-ever measurements of these dissolved noble gas isotopes in groundwater at high precision (
