| 摘 要： | 近20多年,济南泉水流量逐渐衰竭,泉水断流时有发生,为保护泉水,恢复泉水喷涌,塑造济南城市形象,该次研究基于50多年的济南地下水勘查、试验和研究成果,实现对城市多源、海量、多期次、多比例尺、异构地质数据的有效管理,然后建立不同地质数据的专业模型,实现对模型时空展布特征的三维可视化再现,并提供对模型的专业处理与分析。最后,从二维三维等水文地质概念模型出发,加入时间维度,由历史积累的时空关系,反映济南城市地下水的时空变化规律,在三维地质模型的基础上实现地下水动态监测数据的嵌入,构成地下水四维地质信息系统,在其空间表征的基础上,介绍了城市地下水的形成,泉水的分布、成因、演化以及泉水断流的原因、保泉供水的对策措施等,引导城市地下水的保护和发展,为政府决策提供参考。

| Abstract: | In recent 20 years, the flow of spring water in Jinan city is gradually exhausting and spring water breaks out. In order to protect the spring water, restore the spring flow, and shape the image of Ji''nan city, based on the groundwater exploration, test and research results in 50 years, effective management of multisource, massive, multiperiod, multiscale and heterogeneous geological data has been realized, professional models of different geological data have been established, threedimensional visualization of the spatial and temporal distribution characteristics of the model has been realized, and professional processing and analysis of the model have been carried out. The accumulated spatialtemporal relationship reflects the temporal and spatial variation law of groundwater. Finally, based on the twodimensional and threedimensional hydrogeological conceptual model, adding the time dimension, temporal and spatial variation law of urban groundwater in Jinan has been reflected from the timespace relationship of historical accumulation. The embedding of groundwater dynamic monitoring data has been realized on the basis of threedimensional geological model, and form the fourdimensional groundwater geological information system in its space. On the basis of spatial representation, the formation logic of urban groundwater, the distribution, origin, evolution of spring water, the reasons for spring water cutoff and the countermeasures for water supply protection have been introduced. It can guide the protection and development of urban groundwater and provide references for government decisionmaking. |
