摘要
The paper researches the status and mechanism of the seawater intrusion from the karst water source of Daweijia in Dalian City.By analysing the regional tectonic conditions,karst development regularity,and groundwater dynamics it focuses attention on studying the plane of seawater intrusion,the vertical distribution rule and the evolution process of seawater intrusion.The results show that the mechanism of seawater intrusion is complicated in this area and mainly affected by multiple actions such as geologic structure,karst development and the excessive exploitation of groundwater.In order to control seawater intrusion,it is necessary to control the extraction of groundwater,build the groundwater monitoring system of this region and establish the underground karst reservoir in the key sections of seawater intrusion.
