摘　　要：海水入侵已成为我国比较突出的环境灾害,严重影响海岸带地区的生态环境与可持续发展。高密度电阻率法在确定海水入侵范围、识别海水入侵界线方面具有工作效率高、成本低等优势,但也存在结果多解性等问题,难以建立统一的判别标准。本研究开展潮汐影响作用下海水入侵模拟实验,在分析不同因素对地层电阻率影响基础上,采用连续的地层电阻率观测方法,通过分析其频率、振幅特征与模拟的潮位数据之间关系来划定海水入侵的范围,进而摆脱单剖面电阻率测量多解性的局限性,建立了一种基于连续高密度电阻率法确定海水入侵界面的新方法。Seawater intrusion has emerged as a significant coastal hazard in our country,profoundly impacting the ecological environment and sustainable development of coastal regions.The high-density resistivity method offers notable advantages,such as cost-effectiveness and efficiency,in delineating the extent of seawater intrusion and identifying its boundary.However,it also presents challenges,including the potential for multiple interpretations of results,which hinder the establishment of a standardized criterion.This study conducted a simulation experiment on seawater intrusion,considering the influence of tides.By analyzing the impact of various factors on formation resistivity,and examining the relationship between frequency,amplitude characteristics and simulated tide level data using the continuous formation resistivity observation method,the researchers successfully outlined the scope of seawater intrusion.Consequently,they overcame limitations associated with multiple solutions in single-section resistivity measurement and proposed a novel approach to determine the seawater intrusion interface based on the continuous high-density resistivity method.
