摘要/Abstract

摘要： 对2009年6月在莱州湾沿岸采集的地下水样品进行水化学特征分析,结果表明:(1)莱州湾东、南岸海水入侵区地下水中的Na⁺和CI^-与TDS之间呈显著相关,地下淡水中对应的相关系数较小,海水入侵区地下水中K⁺、Ca²⁺、Mg²⁺、SO^2-₄ 也与TDS有较为明显的正相关;(2)根据离子比值特征分析,南岸海水入侵区地下水阳离子交换程度普遍高于东岸,其淡化历史也较东岸长;(3)莱州湾沿岸地下水,由电导率推算的矿化度值同实测值之间的相对误差均较小,在海水入侵监测中可以利用电导率作为矿化度的替代指标。

Abstract: The chemical composition of underground water samples in the coast area of Laizhou Bay was analyzed. The results show that: (1)the correlative coefficient among Na⁺、Cl^-and TDS of the underground water reached significant level in seawater intrusion area in eastern and southern coasts of the Laizhou Bay, while that in the underground fresh water was much less. The correlative coefficient among K⁺、Ca²⁺、Mg²⁺、SO^2-₄ and TDS of the underground water in seawater intrusion area reached a high level; (2)according to the characteristics of ionic ratio, the degree of ion exchange of the groundwater in the seawater intrusion area of southern Laizhou Bay is generally higher than that in the eastern coast, and its history of desalination is also longer than that in the eastern coast; (3) relative error between the calculated values of TDS by using the data of electrical conductivity and the the measured values was vary small in the coast area of Laizhou Bay, so the electrical conductivity was suggested as a substitute indicator for TDS.

Key words: Laizhou Bay, seawater intrusion, hydrochemistry, electrical conductivity
