Intense Human Activities Induce the Dynamic Changes of Interaction Pattern Between Karst Water‐Quaternary Groundwater in the Basin‐Mountain Coupling Belt Over the Past 60 Years

Water Resources Research, Volume 60, Issue 2, February 2024.
Abstract Karst water are important for water supply and ecological protection. However, climate changes and human activities have caused severe water supply crisis. The Jinci spring, one of the famous karst springs in China, is located at the basin‐mountain coupling belt and dried up since 1994.
