摘要
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 。
The serious lack of water resources is the main factor that restricts the development of industry and agriculture in Fucheng County. Because of the natural geography,surface water resource is very limited in this county.In this region most shallow groundwater is salty or slightly salty.The groundwater has been over-exploited.So the groundwater level drops down.From 1980 to 1993 the interface between the salty and fresh water falls about 10~20 meters,and the quality of deep groundwater has been changed.Salty water enters this region,and the mineral degree of deep groundwater increaes by 0 3g/L generally.For this reason,countermeasures are suggested.
