GIS-based approaches for spatially dividing groundwater chemical types
Abstract：For more objectively and efficiently dividing groundwater chemical types,Voronoi diagram and DTM method were employed to spatially divide groundwater chemical types based on GIS respectively,and the coal measures sandstone fracture aquifer of Panyi Mine was used as a case to verify the two methods.The results indicate that these two GIS-based methods are feasible in spatially dividing groundwater chemical types,and the division results of the instance application by the two methods are consistent.The DTM-based method can better reflect the variety characteristics of the data in space,and has a better visual effect.
