北京市丰台区东高地岩溶裂隙水与第四系地下水的水力联系

专家一般认为东高地地区寒武系岩溶裂隙水的补给来源以上游的佣向径流为主，与第四系地下水没有明显的水力联系；通过近来地下水位动态监测和岩溶裂隙水的同住素成分研究，我们认为寒武系岩溶裂隙水与第四系地下水之间有着明显的水力联系。

The Connection between the Karst Fissure Water in the Donggaodi Area and the Quaternary Water

It was thought that the recharge source of the Cambrian karst fissure water in the Donggaodi area was dominated by the upstream lateral run-off, and there was no notable hydraulic connection with the Quaternary water. However, through studies of the dynamic groundwater table, isotope analysis of the karst fissure water etc., we believe that there is an obvious hydraulic connection between the Cambrian karst fissure water in this area and the Quaternary water, and the recharge of Quaternary water through weak permeable layers accounts for a large proportion among the sources.
