东营地区海水入侵与土壤盐渍化现状分析

Analysis of the current situation of seawater intrusion and soil salinization in Dongying area

该文研究分析了2020-2022年东营市海水入侵和土壤盐渍化状况及趋势变化。在东营市河口区、垦利区、广饶县设置监测站位,分别于枯水期和丰水期进行采样监测,监测结果中地下水(水井水)的氯离子浓度指标超过1 000 mg/L,表明监测区发生严重海水入侵。根据土壤盐渍化监测结果,东营沿海地区土壤盐渍化程度也较高。对比发现电导率和氯离子监测数据存在一定的相关性,这可用于野外现场调查时快速判定海水入侵程度。总得来看,海水入侵和土壤盐渍化状况及变化趋势暂无明显规律性,有待进一步优化监测站位进行长期监测和研究。

The paper studied and analyzed the status and variation trend of seawater intrusion and soil salinization in Dongying city from 2020 to 2022.Monitoring stations were set up in Hekou district,Kenli district and Guangrao county of Dongying city,the taking of sample were performed in dry season and wet season,chlorine ion concentration indicator in groundwater(well water)exceeding 1000 mg/L in the monitoring results,Indicates that significant saltwater intrusion is occurring in the monitoring area.According to the results of soil salinization monitoring,the degree of soil salinization is also higher in coastal areas of Dongying.Comparisons revealed some correlation between conductivity and chloride ion monitoring data,which can be used to quickly determine the extent of seawater intrusion during field site investigations.Overall,there is no obvious regularity in the status and trend of seawater intrusion and soil salinization,pending further optimization of monitoring stations for long-term monitoring and research.
