Research progress of groundwater pollution source identification based on process simulation
Groundwater is an important water resource.Compared with air and surface water,groundwater pollution has the characteristics of concealment,lag and irreversibility.After the occurrence of groundwater pollution,the information of pollution sources(quantity,location,release history)can be quickly grasped through the identification of pollution sources,which plays an important role in the prevention and control of groundwater pollution sources,the reasonable design of pollution remediation programs,and the accurate identification of pollution responsibilities.In this paper,the mathematical equation inversion method based on process simulation in groundwater pollution source identification was reviewed.Besides,the relevant literature based on CiteSpace and VOSviewer bibliometric software was analyzed to obtain the research status and hot spots in this field.Finally,the future development trend in the research of mathematical equation inversion based on process simulation was put forward.
