摘　　要：山东省是资源性缺水省份,济南东南部山区作为济南市的重要地下水补给区、生态功能区和流域水环境保护区,其水质环境非常重要。为加强济南东南部狼猫山水库上游山区地下水化学特征的研究,于2012年对该地区水样进行了采集和分析。结果表明,济南东南部山区地下水主要受碳酸盐岩控制,为中等硬度的HCO_3·SO_4^-Ca型清洁与尚清洁淡水,p H在7.1~7.3之间,呈弱碱性,总溶解性固体(TDS)在(190~470)mg/L之间,无色、无味、无臭,透明,口感良好。各种元素含量较为适量,特别是Na^+、SO_4^(2-)、Cl^-含量,都远小于中国和世界卫生标准,所采水样硬度为中等硬水-淡水,主要阳离子Ca^(2+)为优势离子,其次为Mg^(2+);主要阴离子为HCO_3^-,其次为SO_4^(2-)。根据中国天然矿泉水评价标准,在界限指标中,部分水样锶(Sr)元素含量接近或者超过矿泉水标准;在限量指标中,除部分地区铁(Fe)元素有少量超标外,其它元素指标都在标准安全范围内,适宜饮用。Shandong lacks water resources and the Jinan southeastern mountain area is an important groundwater recharge area, ecological function area and basin water environment protected area. This area＇s water quality environment is important. In order to strengthen research on the chemical characteristics of groundwater in the upper reaches of the Langmaoshan Reservoir,we collected and analyzed water samples from the Jinan southeastern mountain area across different geological backgrounds in 2012. We found that the groundwater in the Jinan southeastern mountain is clean or almost clean freshwater; the hardness of water samples belong to medium hardness. The dominant hydrochemistry type for these water samples are Ca-HCO3-SO4 type; the elements in this water samples are mainly controlled by carbonate rock. Water samples were weakly alkaline; the p H values were between 7.1-7.3. Total dissolved solids were between（190-470）mg/L. The water was colorless, tasteless, odorless, transparent and has a good drinking taste.The concentration of each element is appropriate, especially the Na-＋, SO4-（2-） and Cl--concentrations which are far less than the Chinese and world drinking-water quality guidelines. The water hardness is moderate hard water-fresh water. Ca-（2＋） and Mg-（2＋） are two dominant cations, and HCO3--and SO4-（2-）are two dominant anions. The strontium concentration of some water samples is close to or exceeds the Chinese Natural mineral water evaluation standard. The iron of some water samples exceeds the limited amount index; other elemental concentrations are within the Chinese and world standard security range and suitable for drinking.
