地下的

Due to the exploitation and utilization of deep groundwater in northern Shandong plain, a lot of environmental problms have been occurred,such as,the regional deep groundwater depression is continuously enlarging,in some area,deep groundwater exhausted and water quality is becoming more and more saltish,as well as land subsidence was aggravated and endemic appeared in some major towns.The reason is that the groundwater exploitation is most concentrated in towns areamabd tge exploiting methods is much more irrational.

摘 要：鲁北平原在深层地下水开发利用过程中，由于开采地段过于集中在城镇，加上不合理开采等因素，出现了区域性深层地下水超采漏斗不断扩大、部分地段地下水资源枯竭和水质咸化问题严重、重点城镇地面沉降加剧及饮用高氟高碘地下水引发的地方病呈上升趋势等诸多水环境问题。
