| 摘 要： | 本文通过初步分析杭嘉湖地区地下水化学和同位素特征,认为地下水的水化学分布存在着一定的分带性.浅层地下水化学类型为Cl,HCO3-Ca,Na型,代表了降水或地表水补给的形成过程,且补给前受到不同程度的蒸发.深层承压水化学类型为HCO3-Ca,Na和HCO3-Na型,代表了以铝硅酸盐矿物溶解为主的形成过程,其补给源为古气候条件下的降水补给.利用氘过量参数d值判断了第I承压水(120～150 m)总体流向为南西至北东,即由杭州和湖州向嘉兴方向径流.

| Abstract: | The hydrochemical and isotope characteristics of groundwater in Hangjiahu area are preliminarily studied in this paper.It is concluded that the hydrochemistry distribution of underwater in this area shows a certain zonation.The chemical types of shallow groundwater are of Cl,HCO3-Ca and Na types,representing the formation process of precipitation and surface water recharge.The chemical types of deep confined water are of HCO3-Ca,Na and HCO3-Na types,representing the dissolution process of aluminosilicate-do... |
