Preliminary analysis on monitoring data of seawater intrusion and soil salinization in three coastal cities in Jiangsu
Seawater intrusion is a common disaster in coastal areas.It is usually associated with other natural disasters,such as deterioration of water quality and soil salinization,which affect normal indus-trial production,agricultural activities and human life.This study was conducted in three coastal cities in Jiangsu(Ganyu district of Lianyungang,Dafeng district of Yancheng,and Qidong city of Nantong)in November 2019 to determine the monitoring sections for sampling,to analyze the basic monitoring indicators of seawater intrusion and soil salinization,and to get a preliminary grasp.The current situa-tion of seawater intrusion and soil salinization disasters in three coastal cities in Jiangsu were reviewed.The results showed that seawater intrusion and soil salinization disasters had occurred in three coastal cities in Jiangsu:severe seawater intrusion and heavy saline soil had occurred in Ganyu and Qidong parts of the survey area.The chloride ion concentration in Ganyu groundwater was as high as 2260.90 mg/L.The chloride ion concentration in the Qidong area was as high as 1472.30 mg/L.The soil salin-ization in Qidong and Ganyu was relatively large,and the degree of seawater intrusion and soil saliniza-tion in Dafeng was relatively light.Based on the current situation of seawater intrusion and soil saliniza-tion intrusion,and the analyzing the causes of intrusion in some regions,it would be helpful for follow up research.
