为了掌握地下水变化的幅度和规律,评价水利资源,进行估量计算,正确地布局井位,确定井深,科学打井。在陕西省水文一队三分队的帮助下,我县从一九七三年三月开始,开展了地下水的动态观测工作,通过两年来动态资料分析,初步确定出县境内地下水静储量为76亿吨。每年可开采量为1.59亿吨。目前全县已开采量达到1.8亿吨/年(其中卫业用2190万吨/年)。在石川河阶地和美原洪积扇两区,由于开发程度较高,每年超
In order to grasp the magnitude and regularity of groundwater changes, evaluate water conservancy resources, carry out estimation and calculation, properly lay out well locations, determine well depths and conduct scientific drilling. With the help of the first unit of Shaanxi Provincial Hydrology First Team, our county started the dynamic observation of groundwater from March 1973 and through the dynamic data analysis in the past two years, we initially determined that the groundwater reserves in the county are 7.6 billion Ton. The annual recoverable amount is 159 million tons. At present, the county has been mining volume reached 180 million tons / year (of which 21.9 million tons for the health industry). In the Ishikawa River terrace and the US original alluvial fan two districts, due to the high degree of development, super
