中文摘要:
      大别山南麓、江汉平原北缘,区内无大型河流分布,地表水资源贫乏;区内主要分布一套元古界变质岩系,裂隙发育较差,地下水资源贫乏。研究结果表明,区内地下水主要为岩溶-孔洞裂隙水、变质岩风化-构造裂隙水、岩浆岩风化-构造裂隙水等三类地下水。在广泛分布的副变质岩区不宜开展大规模找水工作,即使在构造密集区域,受岩性影响,也不利于地下水的大规模汇集;局部分布的正变质岩区、岩溶区、岩浆岩区,在生产生活需要的前提下,可选择构造发育地区或岩溶发育地区开展局部找水工作,寻找富水构造,开采地下水资源。
英文摘要:
      The southwest piedmont area of Dabieshan mountains is located at the north margin of Jianghan plain. No large rivers flow and the surface water is depleted in the area. A sequence of Proterozoic metamorphic rock occurrs here with less developed cracks thus undergroud water also depleted. Karst-cavern fissure water, metamorphic rock weathering-structural fissure water are the three main types of underground water. The wide spread parametamorphic rock areas, even at the area with dense structure are not suitable for large-scale water exploration because the lithology is not conducive to large-scale groundwater collection. According to the production and living needs local water prospecting can be preferentially carried out at areas where structure or karst are developed to search for the water-concentrated structure and exploit the water resources.
