摘　　要：北方岩溶水系统具有固定补给范围和资源要素,是岩溶地下水进行独立循环的基本单元,控制了岩溶水的运移富集、水化学演化特征、资源构成以及环境地质问题。开展岩溶水系统研究的首要任务是确定系统边界位置及其水文地质性质。以北京西山黑龙关泉域岩溶水系统为研究对象,采用地质学、岩溶动力学、流体动力学、水文地球化学、地球物理勘探等方法,确定黑龙关泉域岩溶水系统是由南部大石河背斜岩溶水子系统和北部百花山向斜南翼岩溶水子系统2个次级系统组成;其含水岩层分别为蓟县系铁岭组、雾迷山组和青白口系景儿峪组、奥陶系、寒武系碳酸盐岩。根据边界的水文地质性质可以划分为地表分水岭边界、地下分水岭边界、隔水边界、岩溶含水层深埋滞流性边界等类型。With a fixed supplied scope and resource elements, karst groundwater system circulates as an inde- pendent unit in northern China, which controls karst water transport and enrichment, hydrochemical evolution, composition of water resources and environmental geological problems. In order to carry out karst groundwater sys- tem research, the primary task is determining the location and hydrogeological properties of boundaries. In this pa- per, we choose Heilongguan karst water system at Xishan region in Beijing as research object and determine the hydrogeological boundaries by geology, karst dynamics, fluid dynamics, hydro-geochemical, geophysical explora- tion and other methods. Finally, we conclude that Heilongguan karst water system is composed of two subsystems. The one is Dashihe anticline karst water subsystem, situated in the south and composed by the Upper Proterozoic aquifer;The other is Baihuashan syncline karst water subsystem, situated in the north and composed by Cambrian-ordovician aquifer. According to hydrogeological properties of boundaries, there are surface water watershed boundary, underground watershed boundary, confining boundaries, karst aquifers deep stagnant boundary and other types.
