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
