摘要
基于土壤、岩石、水体的电性、放射性及磁性差异,通过了解水体、土壤及岩石的物性变化,进行构造填图,研究和评价水资源环境,总结出沿海岸地带影响水环境的三个主要因素:一是地质运动使其遭受海侵事件影响;二是由于现代人类活动造成地下水位下降,引起地面沉降,海水渗透侵入;三是天然或人工核辐射源污染水质和生活环境。
On the basis of the electric,radioactive and magnetic differences of soil,rock and water body and through investigating physical character variations of these three bodies,the authors conducted structural mapping and studied and evaluated water resource environment.It is concluded that three major factors have affected the water environment of coastal areas,i.e.,the influence of marine transgression caused by geological movement,the surface subsidence resulting from the falling of the underground water level caused by human activities,and the water quality pollution and living environmental pollution from the natural and human-caused nuclear radiation.
