山东烟台大季家地区海水入侵界面划分的意义

在沿海地区划分海水入侵界线具有重大意义,在海水入侵范围内,地下水由于含盐量高,虽然工业生产、人畜生活不能利(饮)用,但深部海水可为海产品养殖业带来较高的利用价值。利用高密度电法和可控源音频大地电磁2种方法准确划分了浅、深部海水入侵界线,并根据电性特征分析探讨了海水入侵区域的由浅至深的侵入特点,推测了不同深度上岩石破碎及富水规律,为探讨沿海养殖业利用温度相对稳定或较高的深部入侵海水进行了积极、有益的探讨。

Significance of Seawater Intrusion Interface Division in Jijia Area in Yantai City of Shandong Province

Seawater intrusion interface division in coastal area has great significance. Within the scope of seawater intrusion, due to high salt content of underground water, it can not be used in industrial production, human and animal life, but deep sea water can bring high value in marine aquaculture. By using highdensity electrical method and controlled source audio magnetotelluric method, seawater intrusion interface between shallow seawater and deep seawater has been accurately divided. According to electrical characteristics, seawater intrusion characteristics which is from shallow to deep has been analyzed and studied, and rock breaking and waterrich regularity in different depth has been predicated. It will provide some references for carrying out coastal aquacultur by using deep intrusion seawater with higher temperature.
