摘　　要：应用高密度电阻率法测量手段,结合水质调查取样,对山东寿光市咸水入侵过渡带的基本特征进行了研究。通过对典型高密度电阻率法测量剖面的视电阻率进行分析,初步确定10Ω·m作为该区域咸淡水分界线的视电阻率指示值,并初步推断了咸淡水过渡带的咸水区、咸淡水过渡区及淡水区的位置。结果表明高密度电阻率法具有高效、省时、成本低等优点,可以配合其他方法,作为大范围咸水入侵监测的有效手段。In this paper,high density electrical resistivity method was employed to study the salt-water intrusion transition zone combined with water quality survey sampling.Through an analysis of typical high density measurement section,10Ω·m is preliminary determined as the apparent resistivity indicator of the brackish water boundary in this area,and the location of brackish water zone,brackish water transition zone and fresh water zone in brackish and fresh water transition zone is preliminarily deduced.The result shows that the high density electrical resistivity method has the advantages of high efficiency,time saving and low cost,and can be used as an effective means to monitor the large range of salt water intrusion together with other methods.
