Abstract: An in-situ monitoring profile was built on the west bank of the Yuehai Lake. The conversion between lake water of the Yuehai Lake and groundwater and its driving conditions were explored by analyzing the dynamics and the dynamic correlation between lake water and groundwater as well as the distribution of deuterium and oxygen isotopes. The results indicated that: ①There was the close dynamic responses between the Yuehai Lake and the shallow groundwater only in the near-shore area; ② In the near-shore area, lake water recharged groundwater obviously within 5-m depth, but its recharge to groundwater deeper than 5 m decreased; ③ High water head resulted from artificial water compensation was the direct driving factor of the conversion from lake water to shallow groundwater in the near-shore area.
