摘要: 运用地下水系统分析理论, 以山西省太原盆地东西山地区为实例, 利用GIS技术对区内岩溶大泉地下水系统进行了圈划.运用岩相古地理、地质构造和水文地质分析方法, 首次提取了研究区岩溶含水系统的区域隔水底板等高线、边山断裂两壁投影图及岩溶水系统图等定量或半定量水文地质信息, 圈划出了东西山岩溶水系统的局部饱水带、饱水带和碳酸盐岩非饱水带.研究结果表明, 西山地区兰村泉、晋祠泉属于同一个岩溶子系统; 西冶泉岩溶子系统是相对独立的岩溶水系统; 东山基岩山区大部分属于娘子关泉岩溶子系统, 且东山岩溶水子系统与盆地地下水有密切水力联系而与兰村泉-晋祠泉岩溶子系统无直接关系.这些为模拟盆地地下水系统和评价北方岩溶地下水资源提供重要的科学依据, 对前人就太原盆地边山岩溶水系统边界的确定和内部结构的划分提法有了新的认识.Abstract: This paper takes the eastern and western mountain areas of Taiyuan basin, Shanxi Province as a case study. On the basis of groundwater system theory and geographic information system (GIS) technique, some quantitative or semiquantitative structural information was first extracted from lithofacies paleogeography, geology, tectonics and hydrogeology in the study area, including the isolines of the base of regional karst-water aquifers, the projective section of both the planes of a fault and the mapping of karst-water system. The distribution of karst aquifers, the stratum permeability, the boundary characteristics and the relationship between the internal and external system all serve the classification of the karst-water system as local zone of saturation, regional zone of saturation and zone of passage. The research results show that in the western mountain area, the subsystem of Lancun spring and that of Jinci spring belong to the same regional karst-water system, and the subsystem of Xiye spring is an independent karst-water system. The majority of eastern mountain area belongs to the subsystem of Niangziguan spring. The subsystem of the eastern mountain area closely related to the groundwater system in the Taiyuan basin has no direct relation with the subsytem of Lancun and Jinci springs. These scientific evidences can effectively be employed to simulate the groundwater system and to evaluate the karst-water resources in the Taiyuan basin. Meanwhile, some new viewpoints about the boundary and the internal structure of the karst-water system have been presented with the demarcation method in this study area.
