红层地下水开发的经济技术条件

THE ECONOMIC AND TECHNOLOGICAL CONDITIONS FOR GROUNDWATER DEVELOPMENT OF RED BEDS

按照一般水文地质调查评价的标准,通常认为红层弱含水岩组中的地下水不具有开采利用价值。根据农村生活需水量小和红层含水层富水性普遍弱但分布广泛的特点,依据勘查示范项目的数据并结合前人已有的成果,重点探讨了红层地下水富水等级的划分和开发利用的经济技术条件,更新了红层地下水资源的价值观,使红层地下水开发具有普遍适用性、技术可行性及经济合理性,对解决红层地区的干旱缺水困难具有重要而普遍的意义。

As a general hydro-geological investigation and assessment criteria, it is generally considered that the groundwater of weak water-bearing rock group in Red Beds is not valuable of exploitation. According to the characteristics of weak hydrous but widespread for the water demand in rural life and red beds aquifer, based on sur- vey data from demonstration projects and combined with the results of our predecessors, it is discussed that the grade division of groundwater water-rich in red beds and the economic and technological conditions of development and utilization, updated the values of red-beds groundwater resources, so that there are more general applicability, technical feasibility and economic rationality for the development of red-beds groundwater. There is important and universal significance to solve the difficulty of drought and water shortage in the red beds region.
