【摘要】 济南市泉群喷涌经历了自流期、自流 -季节断流期、季节性断流或长年断流期、人工调控期等几个历史阶段。本文在分析济南市四大泉群喷涌历史演变的基础上 ,利用统计资料 ,首先建立泉群年平均喷涌量与年最低地下水位之间的定量方程 ,得出四大泉群喷涌的底限水位与最低景观流量的对应关系 ,然后 ,计算泉域内地下水的入渗补给量 ,再得出保证泉涌的地下水最大允许开采量的控制性参数。最后 ,结合保泉供水的实际需求 ,提出扩大地表水供应量、开辟新水源、实施多种形式的人工回灌以及调整供用水结构、实施分质供水等宏观调控措施。更多还原

【Abstract】 WT5BZ]The process of Jinan springs spurting can be divided into several periods including artesian flowing period, artesian flowing-exploiting mixed period, seasonal or perennial zero-flow period and artificial controlling period. Based on the analysis of the historical evolution of Jinan springs’ spurting, a quantity equation between the annual average spring discharge and the annual lowest water table is built according to the statistic data, which enable us to gain the corresponding relation between baseline water level and the smallest scenic discharge of spring gushing. Then the groundwater recharge in the spring area is calculated and the controlling parameter of maximum available amount of groundwater exploiting is obtained. Finally, in the light of actual demand, some macro-methods are put forth as follows, expanding surface water supply, exploiting new water source, implementing various types of artificial recharge engineering, adjusting the pattern of water supply and practicing water supply by different quality.更多还原
