摘　　要：文中通过对淄河源区的实地调查、钻孔岩心分析及区域地层对比,研究了淄河源区地下水的赋存条件和含水层介质特征,将源区划分为三种主要的含水岩组类型:松散岩类孔隙水含水岩组、碳酸盐岩类裂隙岩溶水含水岩组及块状岩类风化裂隙水含水岩组,并预判出四个潜在的富水靶区:向斜轴部附近区、河床切割较深区、断裂交汇区、松散层覆盖较厚区。经过钻孔抽水试验,富水区单孔涌水量大于1L/m·s,绝大多数孔出水量均较丰富,其中,七个孔的稳定出水量均在4200 m^3/d以上,结果表明拟建水源地所选潜在靶区正确,水源井孔位设计合理。研究成果将对区域水资源高效利用及生态环境保护提供科学决策依据,也为同类地区找水提供科学借鉴。In this research, the occurrence conditions of groundwater and the characteristics of aquifer medium in the Zihe source area were studied by field investigation, borehole core analysis and regional stratigraphic comparison. Water sources could be mainly divided into three types of water-bearing rock groups: loose rock pore water-bearing rock group, carbonate rock fissure Karst water-bearing rock group, massive rock weathering fissure water-bearing rock group. Four potential water abundance target areas are predicted: the area near the synclinal axis, the deep riverbed cutting area, the fault intersection area and the thick loose layer cover area. By the drilling pumping test, the water influx of single hole in the water-rich area was obtained about 1 L/m·s, the most holes are abundant in water output and the seven among them are above 4200 m^3/d. Correct potential target area of water source and reasonably well location design are proved. Thus, it can provide scientific decision-making basis for efficient use of regional water resources and ecological environmental protection, and also be a scientific reference for finding water in similar areas.
