本文提出北京西山香峪向斜的奥陶系灰岩层是一个深埋地下千米的独立的储水和输水构造.构造西端翘起,被永定河切割,接受河水的渗漏量达10立米/秒,构造东北端的两翼,岩溶水出露成泉,如玉泉山泉、黑龙潭泉、白家疃泉、温泉等,在个别地段,承压岩溶水透过第三系地层补给永定河冲积扇.其东南翼被八宝山逆掩断层超复后又被坨里～洼里正断层所切,造成岩溶水参与深部震旦系地层热水循环. 正确认识这个输水构造,不仅是正确评价北京市地下水资源的一个重要条件,而且如果这个构造有永定河水补给的保证,则对日益恶化的北京市地下水现状的改善和北京市热水资源的增加,都将起到积极的作用.
This paper proposes that the Ordovician limestone layer of Xiangxiang syncline in Xishan, Beijing, is an independent water storage and water delivery structure with a depth of 1000 km underground.The structure is tilted at the west end, cut by Yongding River, and the seepage of water reaches 10m / Second, the construction of the two wings of the northeast end, karst water out into the spring, such as Yuquan spring, black Longtan spring, Baijiquan spring, hot springs, etc., in individual areas, pressured karst water through the Tertiary formation recharge Yongding alluvial fan The southeast wing was overthrown by the Babaoshan overthrust and was cut by the Tuoluli-Wali normal fault, causing the karst water to participate in the hot water circulation in the deep Sinian strata. Correctly understanding this water conveyance structure is not only a correct assessment of Beijing Groundwater resources, and if this structure is guaranteed by Yongding river water supply, it will play a positive role in the deteriorating groundwater situation in Beijing and the increase in hot water resources in Beijing.
