四川温江金马地下水开发利用研究(附答辩文稿)

摘 要 本次实习针对成都市温江金马地区地下水进行了调查研究。其地下水分为两层，即上部潜水含水层和下部承压含水层。 上部含水层厚25米左右，主要为粘土层和砂层。水量较为丰富，一般埋深8-10米，以HCO3-Ca型及HCO3·SO4- Ca型水为主，部分微量元素有超标现象，特别是铁离子超标现象严重。 下部含水层埋深60米，厚75米左右,间杂透晶体，分布不均匀，主要为砂砾石层。以HCO3-Ca型水为主，其水质较好，未受污染。 关键词：成都平原、地下水、水质、水量 Abstract In this practice , we made investigation to the groundwater of Jinma district in Wenjiang.The groundwater of there can be divided into two types : the first aquiferous and the second aquiferous. The first aquiferous is composed of claypan and sand bed .The thickness of it is about 25m .There is abundance water source . Always the depth of this aquiferous is 8m-10m . HCO3-Ca and HCO3·SO4- Ca is the primary type of water in this area .The concentration of some trace element exceed the criterion .Particularly iron ion . The thickness of the second aquiferous is about 75m .The depth of the water of this aquiferous is 60m . This aquiferous is very asymmetry .The primary type of the water is HCO3-Ca . The water of this aquiferous is not be polluted and the water quality is very fine. Key word : Chengdu plain 、groundwater 、Water quality 、Water quantity
