摘要:
以济南地区地质、水文地质条件为基础，论述千佛山所在流域及其毗邻流域与济南泉水的关系。指出大千佛山景区为济南泉水直接补给区的一部分，千佛山断层并非泉水补给的南北向通道。勘察资料表明：济南泉水来自东南部以石灰岩为主的小清河流域，名泉20年断流干涸的原因是由于济东地区过量开采地下水造成的。全面停采济东地下水，可确保名泉持久正常喷涌。有十几项确凿证据证明：以刘长山一带的火成岩体为界，济西地区为独立于济南泉域之外的地下水系统，全面、合理开发济西地下水不影响名泉喷涌。济西地下水供水潜力巨大，作为保泉替代水源，完全能够满足济南市供水需求。落实省、市两级政府“采西停东”的保泉供水决策和济南“南控”战略，乃济南保泉供水成功的根本途径。大千佛山景区应当成为泉水直接补给区保护的样板。
Based on the geological and hydrogeological conditions in Jinan, this paper discusses the relationship between adjacent watershed and Jinan spring water. It is pointed out that the Qianfo Mountain scenic spot is a part of the direct recharge area of spring water and the Qianfo Mountain fault is not the north- south channel of spring water supply. Geological survey data show that: Jinan spring water from the southeastern limestone distribution area of the Xiaoqing River basin, the famous springs 20 years drying up due to the eastern region of over-exploitation of groundwater caused. To ensure the long-term normal spewing springs, the pumping groundwater in the Jinan eastern region should be stopped. There are a number of conclusive evidences to prove that the Liuchang Mountain area of igneous rock as the boundary and the western region of Jinan are independent of groundwater system with spring area. The comprehensive and rational development of the groundwater of Jinan western region does not affect the Jinan spring spewing. As an alternative source of spring protection, the potential of groundwater in Jinan western region is huge, which can fully meet the demand of water supply. Implementation of the provin-cial and municipal levels of governance “mine western region and stop pumping eastern region” of the protection of spring spewing and spring water supplying decision-making and “control the city southern development” strategy, is the fundamental way protection. The Qianfo Mountain scenic spot should be a model for the protection of the direct spring water recharge area.
