It is caused by continuously withdrawal of groundwater. The distribution of seawater incursion areas shows a consistence with that of the groundwater zone of negative table values, and both of them indicate an identical extending trend. Based on monitored data of groundwater withdrawal and seawater incursion, the relation between excessive withdrawal of groundwater and seawater incursion is analyzed by regression method. The results show that volume of excessive withdrawal of groundwater is closely related with values of the seawater incursion area. The measures and suggestions for controlling seawater incursion are also put forward.展开更多
