摘要
为研究鲁西沿黄地区的地下水循环特征及黄河水、东平湖水的渗漏补给范围,利用水化学、D、^(18)O同位素识别地下水中主要水化学组分来源及控制性因素确定了补给范围,利用地下水动力学方法和端元混合模型对黄河水及东平湖水的渗漏量、不同水体之间的转化进行了定量计算;并将上述成果与地下水动力学结合探究鲁西沿黄地区地表水地下水循环的演化规律。结果表明:研究区地下水水化学类型主要以HCO_(3)^(-)—Ca^(2+)·Mg^(2+)型为主,水化学组分受硅酸盐岩的风化溶解作用控制;黄河水及东平湖水渗漏补给影响带范围分别为1.5~4.5 km、0.5~1.5 km;丰水期(2023.6~2023.9)黄河水及东平湖水渗漏量分别为:457.63×10^(4)m^(3)、222.80×10^(4)m^(3);枯水期(2023.10~2024.5)分别为261.50×10^(4)m^(3)、456.91×10^(4)m^(3)。研究区地下水以大气降水为主,黄河水渗漏补给两侧第四系孔隙水,东平湖水侧渗补给周边第四系孔隙水;孔隙水接受大气降水及黄河水、东平湖水补给后下渗补给下伏岩溶水。地下水地表水循环演化研究成果可为该地区地下水资源量的计算提供参考。
Objectives:In order to clarify the influence zone of seepage recharge pore water in the Yellow River and Dongping Lake,and to clarify the evolution law of surface water groundwater circulation along the Yellow River in western Shandong Province.Methods:The sources and controlling factors of the primary hydrochemical components in groundwater were identified through groundwater chemistry and isotope analysis.Additionally,the seepage from the Yellow River and the Dongping Lake,and the leakage quantity and the transformation among different water bodies were quantitatively analyzed.Results:The research shows that the main hydrochemical types are HCO_(3)^(-)—Ca^(2+)·Mg^(2+)type,followed by HCO_(3)^(-)—Ca^(2+)and HCO_(3)^(-)·SO_(4)^(2-)—Ca^(2+)type,and the hydrochemical components are controlled by the weathering and dissolution of silicate rocks.Through the application of groundwater dynamic field,hydrochemistry and isotope methods,the influence zones of water seepage and recharge of the Yellow River and Dongping Lake are calculated to be 1.5~4.5 km and 0.5~1.5 km respectively.During the wet season(June,2023~Sept.,2023),the water leakage of the Yellow River and the Dongping Lake was 4.5763×10^(4)m^(3)and 2.2280×10^(4)m^(3)respectively.During the low water period(Oct.,2023~May,2024),it is 2.6150×10^(4)m^(3)and 4.5691×10^(4)m^(3)respectively.Conclusions:The groundwater in the study area is mainly replenished by atmospheric precipitation,and the water level of the Yellow River is higher than the ground on both sides,with leakage replenishing the Quaternary pore water on both sides.The surrounding terrain of the Dongping Lake is high in the northeast and low in the southwest,and the lake water permeates the surrounding Quaternary pore water.The pore water receives atmospheric precipitation and water from the Yellow River and the Dongping Lake,and then permeates and recharges the underlying karst water.The research results of groundwater—surface water cycle evolution can provide a reference for the calculation of groundwater resources in this area.
