水资源匮乏是制约阜城县工农业生产发展的主要因素。由于该县工农业生产及生活用水主要依靠开采深层地下水 ,造成了地下水的严重超采 ,使地下水位下降 ,咸淡水界面下移 ,深层地下水水质发生变化。经初步研究从1980～ 1993年 ,该县深层地下水咸淡水界面下移了 10～ 2 0 m,咸水入侵范围遍及全县 ,深层地下水矿化度平均升高 0 .3g/L。利用以往及近期采用地面电测法对咸淡水界面进行探测获得的资料 ,从水文地质、成井结构、开采强度等方面 ,分析了界面下移的原因 ,提出抑制界面下移的措施 Water scarcity is the main factor restricting the industrial and agricultural production in Fucheng County. Because the county’s industrial and agricultural production and domestic water mainly relies on the exploitation of deep groundwater, serious over-exploitation of groundwater has resulted in a decrease of groundwater table, a shift of the salt-to-freshwater interface and a change of groundwater quality. Preliminary studies from 1980 to 1993, the county deep groundwater salt water freshwater interface down 10 ~ 20m, the scope of salt water intrusion throughout the county, the average depth of groundwater salinity increased 0.3g / L. Based on the past and recent data obtained by the ground electrical measurement method for the detection of the salt-freshwater interface, the reason of the downward movement of the interface was analyzed from the aspects of hydrogeology, well-formation structure and mining strength, and the measures to suppress the downward movement of the interface
