跨界含水层由位于不同国家的含水层组成，是地下水资源系统的重要组成部分。妥善管理并公平合理地利用跨界含水层，对促进可持续发展及国家之间的睦邻友好关系有着重要意义。通过分析澜沧江-湄公河流域水文地质奈件，划定流域的跨界含水层系统，并对地下水资源与环境问题进行探索，提出跨界含水层综合评价指标体系，结合澜沧江-湄公河流域4个跨界含水层相关的指标进行了综合评价。本次研究，对管理澜沧江-湄公河流域跨界含水层，建设和谐的东南亚国际环境有着重要意义。%Trans-boundary aquifer is an aquifer system that exists in more than one state. As an important com ponent 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 Lancang - Mekong 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 aqui- fers in the Lancang Mekong Basin. The study is of significance for the management of Lancang- Mekong River trans boundary aquifers and the construction of harmonious international environment in Southeast Asia.
