沂蒙缺水地区碳酸盐岩地下水富水性研究

Study on Underground Water Rich Property in Carbonate Roch in Water Shortage Area in Yimeng Area

沂蒙缺水地区地处山东省中南部,大面积分布泰山群变质岩及各类侵入岩,赋水性极差,生活、生产用水非常困难。通过研究地层岩性、地质构造、地形地貌、补给条件和水动力条件,在地形、构造、岩性复合的有利部位发现蒙阴-桃墟、沂水-姚店子和马牧池等3处裂隙岩溶富水地段,水质良好,具备建设中、小型水源地的条件。认为地层岩性是控制地下水存在的基础、地质构造控制着地下水的运动和赋存条件、地形地貌是影响地下水补给及运动最主要的因素等地下水赋存规律;研究成果对解决区内用水困难具有重要意义。。

Water shortage area is located in the south ol Shandong Province. Metamorphic rocks ol Taishan group and various intrusive rocks distributed widely. Water bearing range, lile and production using water are very short-age .Through study on lithology, geological structures, topography, supply conditions and hydrodynamic conditions, three Iracture karst water rich areas, such as Mengyin - Taoxu, Yishui - Yaodianzi and Mamuchi have been lound in topography, lithology and tectonic complex lavorable positions. Water quality is good and can construct medium and small water sources. It is regarded that lormation lithology is the basis lor controlling the existence ol groundwa-ter, geological structure controls the movement and occurrence ol groundwater, topography and geomorphology are the main lactors aflecting groundwater recharge and movement. It has important significance lor solving water short-age in this area .
