Study on Causes of Discontinuous Flow in Spring Group of Longmen Grottoes in Henan

龙门石窟是我国珍贵的历史文化遗产,近年来,龙门石窟景区内的龙门泉群流量逐年变小,甚至出现断流的现象。文章通过对整个龙门泉域边界条件及性质、泉群出露条件与成因类型、泉水的形成条件、同位素与氟利昂技术及地下水开采现状等多方面分析研究,探讨了龙门泉群的形成及其间歇性断流、干枯的原因,提出龙门泉域岩溶水水资源合理发利用保护规划建议,为泉域地下水资源保护规划及治理提供科学依据。

Longrnen Grottoes is a valuable historical and cultural heritage in China. However, with the changes of natural factors and increasing of human activities in recent years, the flow of the Longmen spring group in the Longmen Grottoes decreased gradually and even discontinued at some time. In this paper, the boundary conditions of the Longmen spring area, the outcrop and formation conditions of springs, the technology of isotope and Freon, and the status of groundwater exploitation were ana-lyzed,and the reasons of the formation and intermittent drying of Longmen spring group were discussed. The suggestions for protection of the Longmen spring group were proposed which can provide a scientific basis for the groundwater protection and management in the spring area.
