摘　　要：本文梳理了巨淀湖附近浅部的地层结构,通过地下水动态监测、水位统测等手段刻画了地下水流场,分析了湖区水文地质特征及三水转化规律。研究结果表明:湖区附近地层结构以多层粉砂质黏土、黏土质粉砂夹粉砂为主,湖区北部地区海相沉积特征明显。浅层孔隙水主要补给有大气降水、灌溉回渗和地表水侧渗,主要排泄方式为潜水蒸发和人工开采,湖水与20 m以浅的孔隙水水力联系密切。研究区咸水入侵现象明显,北部地下水为Cl-Na型,南部为HCO_(3)·Cl-Na·Ca·Mg型,TDS含量由北向南逐渐降低。该研究为巨淀湖生态保护修复方案提供地质支撑,对提高湖区蓄水量,恢复湿地功能对维持生物多样性,改善区域生态环境有积极作用。Shallow geological structures near Judian lake have been set up.Through groundwater dynamic monitoring,water level measurement and other means,groundwater flow field has been introduced,and hydrogeological characteristics and three types water transformation laws of the lake area have been analyzed.It is showed that geological structures near the lake area are mainly composed of multiple layers of silty clay and clayey silt interbedded with silt,and the marine sedimentary characteristics are obvious in the northern part of the lake area.The shallow pore water near Judian lake is mainly supplied by atmospheric precipitation,irrigation backflow,and surface water lateral seepage.The main discharge methods are groundwater evaporation and artificial mining.There is a close hydraulic connection between lake water and pore water shallower than 20m.The phenomenon of saltwater intrusion is obvious in the research area,with Cl-Na type groundwater in the north and HCO_(3)·Cl-Na·Ca·Mg type groundwater in the south.The TDS content gradually decreases from north to south.This study willIt provide geological support for ecological protection and restoration plan of Judian lake,improve the water storage capacity of the lake area,and maintain biodiversity and improve regional ecological environment.
