| 摘 要： | 大沽河下游平原区沉积了丰富的砂层，平面上呈串珠状分布，厚3～8m，下伏白垩纪红砂岩不透水层。该砂层由上亚层全新统细中砂和下亚层晚更新统砂砾石组成，具高角度斜层理、槽状交错层理和平行层理，下亚层还有铁染和钙质结核。砂层水质好，水量大，最大含水量达22448．12万m^3，枯季含水量达7404．37万m^3，是青岛市理想的水源地。

| Abstract: | There are abundant sand layers in the Dagu River plain, which are 3~8 m thick and like a string of beads in the plane distribution. Under the sand is Cretaceous unpermeable red sandstone.The sand is composed of fine-medium-grained sand (Q 4) in the upper and gravel (Q 3) in the lower,in which can be found high-angle oblique bedding, trough cross bedding and parallel stratification. In addition, the lower sublayer has iron rust and is cemented by Ca. The sand layer is of good water quality and abundant water quantity,and contains 224 481 2 million ton of water in flood season and 74 043 7 million ton of water in dry season,so it is considered as water resource for Qingdao city. |
