摘　　要：为了更加客观、高效地进行地下水水化学类型空间划分,基于GIS技术,分别采用Voronoi图和DTM方法进行地下水化学类型的空间划分,并以潘一矿煤系砂岩裂隙含水层为例,对两种方法进行了验证。结果表明:这两种基于GIS的地下水化学类型分区方法可行,且在实例应用中分区结果总体一致,基于DTM的方法能更好地反映数据在空间上的变化特征,且可视化效果相对更好。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.
