在海水入侵的研究中 ,由于不同地区的地下水特征不同 ,运用统一的海水入侵判定标准 ,对判定研究区的海水入侵会产生很大的误差 ,因此本文根据深圳地区孔隙水和裂隙水的特征 ,分别对其海水入侵的标准进行了分析。为了较准确的确定出该研究区的地下水背景值 ,运用Grubbs统计方法对数据中的干扰数据进行剔除 ,并运用SPSS统计软件 ,在判定各项组分分布类型的基础上 ,确定出不同类型的地下水的环境背景值。同时提出了该研究区的海水入侵的判定标准值。
In the study of seawater intrusion, due to the different characteristics of groundwater in different regions, the application of a unified standard of determination of seawater intrusion will produce a great error in the determination of seawater intrusion in the study area. Therefore, according to the characteristics of pore water and fissure water in Shenzhen, The standards of seawater intrusion were respectively analyzed. In order to more accurately determine the background value of groundwater in the study area, Grubbs statistical method is used to eliminate the interference data in the data and use SPSS statistical software to determine the distribution types of each component based on different types of Groundwater environmental background value. At the same time, the standard value of seawater intrusion in this study area is proposed.
