摘要: 利用山东莱州湾沿岸海水入侵监测剖面的水化学监测数据,从水化学指标与Cl-含量的关系入手,采用不同侵染程度组段将所选定的水化学指标对Cl-含量作回归分析的方法,对海水入侵过程中浅层地下水水化学特征变化作了研究。研究表明,多数水化学指标及几项灌溉水质指标与侵染程度有较明显的宏观相关性,但不是简单的线性关系,两个剖面分析数据的对比揭示出莱州湾东部与南部沿岸海(咸)水入侵的区域差异性。

Abstract: Using the data of the water samples of seawater intrusion monitoring in the coastal area of Laizhou Gulf,Shandong Province, and adopting the method of linear regression conducting in respective groups of intrusion degree, the author made a study on the relation between series of hydrochemical indexes and the Cl- content, which involves 13 indexes including some main hydrochemical compositions of the water and the water quality indexes for irrigation.So the changes of the hydrochemical indexes in the process of seawater intrusion are shown by a series of linear regression equations with different slopes and relation coefficients. The analysis results also show the difference of seawater intrusion in the southern and eastern of coastal regions of Laizhou Gulf,the author considers that it is mainly because of the difference in the intrusion sources (current seawater or coastal underground salt water), salinization history and its affecting degree in the different parts of the coastal regions of Laizhou Gulf.
