岩溶介质非均质性导致岩溶水运动复杂,精细刻画岩溶水动力过程是水文地质领域亟待突破的难点问题之一。项目以济南泉域为例,从岩溶含水介质的空隙结构特征入手,采用野外试验、室内实验等工作手段,结合分形理论、频率分析、时间序列分析、三维图像数字建模等新技术,研究岩溶水系统优势径流通道特征。取得主要成果如下:1岩溶大泉排泄区介质结构特征研究表明,岩溶含水介质孔隙结构类型及渗透性差异性巨大;分形维数与孔隙度是正相关;岩溶径流通道为单一管道型与多管道型并存;且毛管束越简单其渗透率越高。不同尺度空隙类型的水力特征研究表明,奥陶纪灰岩岩溶最发育、连通性好,其次是寒武纪张夏灰岩、凤山组灰岩;泉域排泄区岩溶连通性优于补给径流区,排泄区地下水平均流速320.8m/d,远大于补给径流区。2研究岩溶发育带、裂隙带水温发现,岩溶区垂向上有四种类型温深曲线;形成了判别水平径流通道的温深曲线拐点法;建立了热传导模型计算表明岩溶水垂向交替速率远远低于示踪试验确定的水平视流速。3制定岩溶区优势渗流通道特征因子判别标准,形成了识别优势渗流通道的模糊评判法。将管道流与渗流耦合提高岩溶大泉水位预测精度。基于优势渗流通道识别,创立了SCE-UA耦合优化算法的模拟—优化反演模型,研发岩溶水污染溯源技术方法。4基于时间序列分析,解析了大裂隙—管道流和裂隙—孔隙流对泉水动态影响,形成了北方岩溶大泉动态对降水时滞响应的判别方法。构建了动态频率分析法和水化学法相结合的泉水补给来源混合比定量计算方法,首次确定趵突泉、黑虎泉、珍珠泉与五龙潭补给来源的混合比。主要创新:揭示岩溶介质不同空隙类型孔隙性与渗透性的定量关系,建立北方岩溶水系统优势径流通道识别方法。研究成果不仅丰富和深化了对岩溶水运动特征的认识,也对北方岩溶大泉保护有指导意义。

    为了研究岩溶水成因及演化,保护岩溶水系统,以济南泉域为例,运用水文地质分析、孔内地下水监测、示踪试验等综合手段,研究和揭示北方岩溶水流系统的分级、成因类型及其演化。结果表明:北方岩溶水系统发育多级次地下水流系统,地形、岩溶发育率是岩溶水流系统识别要素。局部地下水流系统可分为溢流型、侵蚀型和接触型;中间地下水流系统分为越流型、人工开采型和断裂溢出型;区域地下水流系统分为顺层型、穿层型和断裂带循环型。局部流动系统多发育于间接补给区,地形、岩性是局部流动系统的主控因素,区域流动系统主要受地形控制。济南泉域内趵突泉、黑虎泉、珍珠泉、五龙潭泉群受区域流动系统补给,动态稳定,南部山区岩溶泉主要受局部流动系统补给,岩溶泉的断流与复现指示局部流动系统发育情况。局部地下水流动系统以泉形式排泄后,就近入渗,补给区域地下水流动系统,维持区域流动系统汇区的岩溶大泉持续喷涌。根据多级次地下水流系统发育特征,圈定济南泉域张夏组灰岩补给范围,将张夏组岩溶含水介质对泉水的补给贡献量由13.54×104 m3/d修正为10.71×104 m3

    岩溶介质的各向异性造成岩溶水动态复杂多变,研究岩溶水系统响应机制对于泉水保护具有重要意义。本文以济南岩溶水系统为例,采用时间序列、相关分析、滑动窗口分析等方法,研究岩溶水动态特征,阐明岩溶水系统中地下水流动系统分级与发育规律,揭示岩溶泉域不同级次地下水流动系统的地下水位动态对大气降水的响应。结果表明:(1)泉域内地下水位响应具有高度的季节性和周期性变化特征,不同级次流动系统内地下水动态各异,局部流动系统地下水动态变化剧烈、变幅大;区域流动系统地下水动态稳定、变幅小。(2)不同级次流动系统地下水动态响应滞后时间不同,具有地域性特征。主要受到地形、地质构造、岩性、裂隙岩溶发育强度的控制。断裂构造、裂隙岩溶缩短地下水动态的响应滞后时间,局部流动系统地下水转化区域流动系统地下水延长岩溶大泉的喷涌时间。(3)不同级次流动系统地下水位对次降水的初始响应时间存在滞后性,局部流动系统响应滞后时间在0.75~2.32 d,区域流动系统响应滞后时间在30.79~33.35 d。岩溶发育、地层岩性、地质构造、裂隙岩溶发育程度是响应滞后时间存在差异性的重要因素。研究成果可望丰富济南泉域多级次地下水流动系统理论...

    The investigation of groundwater quality and hydrochemical assessment holds immense significance in safeguarding and ensuring the rational utilization of groundwater resources. This study utilizes groundwater sampling and testing data from the Laiwu region (LWR), encompassing both dry and wet seasons, to delve into the hydrochemical characteristics, ion sources, and overall groundwater quality. The research findings indicate that the groundwater in LWR exhibits weak alkalinity, with the dominant ions being Ca2+ followed by Mg2+, Na+, and K+, and HCO3-, SO42-, NO3-, Cl-, and F-. The average total dissolved solids (TDS) concentrations during the dry and wet seasons are recorded as 683 mg/L and 679 mg/L, respectively, classifying LWR's groundwater primarily as hard-fresh water. The spatial pattern of TDS concentration in LWR displays consistency throughout both the dry and wet seasons, with relatively low TDS levels observed in the northern and southeastern regions and higher concentrations in the lower reaches of the Dawen River and nearby Gangcheng. Predominantly, Ca2+, Mg2+, and HCO3- ions in groundwater originate from the dissolution of calcite and dolomite, with the hydrogeochemical process of carbonate rock weathering involving the presence of sulfuric acid. It is noteworthy that human activities significantly impact the chemical composition of groundwater in LWR. Notably, during the dry and wet seasons, the average concentration of NO3- in groundwater is 102.81 and 106.61 mg/L respectively, and the analysis shows that agricultural practice is the main source. Furthermore, the calculated average values of the entropy water quality index (EWQI) during those seasons are 58.44 and 57.24, respectively. The EWQI shows good to moderate water quality in most areas, except for a few poor-quality spots in the west. It is worth mentioning that LWR's groundwater is deemed suitable for agricultural irrigation. These research findings provide valuable insights and serve as a significant reference for the rational development and sustainable utilization of groundwater resources in the LWR region.

    数值模拟是解决地下水开采评价问题的有效途径之一。为安全高效开发岩溶塌陷区地下水资源,以山东省临沂市岩溶区为例,根据水文地质调查分析,充分掌握了岩溶区地下水补给规律、运移规律、分布规律,在此基础上,选取合理模拟范围,建立数值模型,开展多方案地下水动态演化数值预测分析,据此来分析评价最优开采方案。研究结果表明:方案一岩溶塌陷危险性较高,数值观测孔水位在第1 279 d、第1 644 d、第2 019 d和第3 105 d时,水位降至灰岩顶板标高39.9 m以下,将引发岩溶塌陷风险;方案二则较安全,数值观测枯水期水位接近灰岩顶板标高,既达到地下水开发利用潜力的标准,又可保证生态地质环境安全,因此,建议采用方案二。开采过程中预警区水位应位于基岩顶板标高以下,以避免岩溶塌陷发生。本文研究结果可为类似塌陷区的科学开采提供参考。

    准确掌握地下水的环境质量状况是合理确定地下水资源开发策略和有效进行地下水资源保护的重要前提。通过随机森林(random forest)法构建弥河-潍河流域地下水质量评价模型,结果表明:(1)随机森林法在进行地下水水质分类时具有分类精度高、泛化能力强等特点,且在进行超参数优化后,其分类精度会进一步提高,证明将随机森林法应用于地下水质量评价是可行的,并且其综合性能要优于逻辑回归模型;(2)研究区地下水水样均为Ⅳ类和Ⅴ类水,说明水质状况整体较差;(3)通过分类指标重要性评价可以看出,研究区地下水水质的主要影响指标为硝酸盐、总硬度和溶解性总固体,而此类指标的主要来源是蔬菜种植化肥的不合理使用及河流污染入渗,因此要进一步加强对蔬菜种植污染排放及河流水质的监测和控制。

    Due to the influences of geological structures, many confined ascending springs occur in North China's karst area. The electrical conductivity (EC) of karst spring flow has been a fundamental variable in characterizing karst systems. However, deeply exploring the hidden nonlinear dynamic characteristics is challenging. To avoid overreliance on the fitting polynomial order in the detrending process by classic multifractal detrended fluctuation analysis (MFDFA), the intrinsic time-scale decomposition (ITD) method was applied to identify the external trend term of the data by decomposing the original data into different frequency modes, and the ITD-MFFA method was proposed to reveal the formation mechanism of spring EC complex characteristics in the Jinan spring area. The results showed that the EC sequences of karst springs in North China are characterized by multifractal behavior and antipersistence and display multiyear complexity with an overall decreasing trend. Different recharge sources, formation conditions, and seasonal precipitation might be the primary factors driving the spring's EC complexity. Compared with the traditional MFDFA method, the ITD-MFFA method improves the anti-interference ability and stability. The timely determination of the dynamic complexity of spring EC data and monitoring the future trends of the spring water quality have guiding significance for protecting karst springs.

    Groundwater shortage and pollution are critical issues of global concern. In Wulian County, a typical hilly area, groundwater is the main source of water supply. This study investigates the current situation of groundwater pollution in Wulian City through the analysis of groundwater water chemistry characteristics, water quality evaluation, and health risk evaluation. After the analysis of the controlling factors of chemical components in groundwater and the analysis of ion sources, the main ion sources in groundwater were determined. The results showed that the major cations in groundwater were Ca2+ and Na+ and the major anions were HCO3 and SO42−. Nevertheless, NO3 exceeded the standard to different degrees in pore water (PW), fissure pore water (FPW), and fissure water (FW). The minimum NO3 concentration exceeded the standard in FW. Under the influence of rock weathering and salt rock dissolution, the main hydrochemical types of groundwater were the HCO3-Ca, HCO3-Ca·Mg, and SO4·Cl-Ca·Mg types. According to the water quality evaluation and health risk assessment, the FW area in the south had the highest water quality, where Class I water appeared and potable water was more widely distributed. The PW and FPW areas in the north had lower water quality, with higher health risks. Category V water gradually appeared in the FPW area, which is not suitable as a water supply source. Factor analysis and ion ratio analysis showed that the study area is strongly affected by anthropogenic factors. These research methods have important reference value to the research of groundwater pollution status.
