摘要
Abstract
The studied area is located within the effected zone of Wenchuan earthquake in southwest Chi-na .In order to evaluate the effect of hydrogeological condition w hich caused by the earthquake , the hydrogeochemical and isotopic research was carried out in southwest China .According to the hydrogeo-chemical and isotopic analysis results ,the pH range of groundwater is from 7.90 to 9.48 ,which is alka-line and the TDS is mostly less than 500 mg・L -1 .The chemical composition of the groundwater changes obviously in vertical direction and is mainly HCO 3 Na type .The analysis of groundwater hydrogen and oxygen stable isotope shows that the groundwater is mainly of meteoric origin .The tritium content de-creases with depth increasing ,which reflects the circulation ability of shallow groundwater is stronger than that of deep groundwater system .It also indicates that the groundwater circulation is mainly vertical in the study area .关键词
