Abstract:

Transboundary aquifer is an aquifer system that exists in more than one state. As an important component of the groundwater system, proper management and rational utilization of transboundary aquifers are significantly important for promoting sustainable development and goodneighbor relationships. The paper analyzes hydrogeological conditions of LancangMekong River Basin and delimits transboundary aquifer systems, as well as explores the groundwater resources and environmental problems. The paper puts forward transboundary aquifers comprehensive evaluation index system, and applies it to the four transboundary aquifers in the LancangMekong Basin. The study is of significance for the management of LancangMekong River transboundary aquifers and the construction of harmonious international environment in Southeast Asia.

Key words: LancangMekong River Basin, transboundary aquifer, groundwater resources sustainable use, indicators system
