Study on Relationship between Groundwater Conductivity and Chemical Characteristics in Seawater Intrusion Area around Laizhou Bay

摘要

Based on the monitoring data in the coastal area of Laizhou bay, the paper presents the correlation between groundwater conductivity and chemical characteristics. The results showed that, compared with titration method,appIication of Diagometer has the advantages of high accuracy,fast speed and simple operation. When the seawater intrusion has not yet occurred or relatively weak,the effect of the application of diagometer is not very obvious. Only when seawater intrusion occurs serious, application of Diagometer can reflect the changes of mineralization degree and chloride ion concentration of groundwater accurately.
