随着首都社会主义建设的迅速发展,工农业生产及城市供水需要量与日俱增。当前,地下水开采量已占总用水量60％以上。由于在地下水开发利用过程中,缺乏科学管理和合理规划布局,造成区域性地下水位大幅度的下降;单井涌水量逐年衰减,地下水源污染,水质恶化及水的硬度逐年升高问题,特别是近年来气候干旱,雨量偏少,严重地威胁着城市正常供水。
With the rapid development of capitalist socialist construction, industrial and agricultural production and urban water supply are in increasing demand. At present, groundwater extraction has accounted for more than 60% of the total water consumption. Due to the lack of scientific management and rational planning and layout in the process of groundwater development and utilization, the regional groundwater table will decrease drastically. The single well water inflow declines year by year, groundwater pollution, water quality deterioration and water hardness increase year by year. In particular, In recent years, the arid climate and less rainfall have seriously threatened the normal urban water supply.
