摘要
探讨了水文地质剖面分析在圈定岩溶含水系统和判定岩溶水流系统边界方面的应用。选取湖北鄂西响水洞岩溶水系统为研究对象,在1∶5万水文地质调查的基础上,通过水文地质剖面分析,结合主排泄点水化学、同位素信息,确定了响水洞岩溶含水系统边界结构和岩溶水流系统边界,并在岩溶水系统圈划的基础上,得出响水洞岩溶水系统的发育主要受地形、弱透水层和断层控制,在三者的共同作用下形成了局部、中间、区域三级水流系统,不同级次对应的主排泄点分别为水磨溪泉、响水洞地下河、钻孔ZK03。
This paper discusses the application of hydrogeological profile analysis to the demarcation of karst aquifer system and to the determination of the boundary of the karst water flow system.Xiangshuidong karst water system in Western Hubei Province is the research object.On the basis of 1∶50 000 scale hydrogeological survey,the paper identifies the boundary and structure of the Xiangshuidong aquifer system through hydrogeological profile analysis with the reference of the water chemistry of main discharge point and isotopic information.Based on the demarcation of karst water system,the paper concludes that the development of karst water system is mainly affected by terrain,aquitard and fault,which contribute to the development of the local,intermediate and regional flow systems.And the main discharge points in different ranks are respectively Shuimoxi Spring,Xiangshuidong underground river,drilling ZK03.
