摘要
Abstract
Lixiviation and evaporation are main salinization processes of groundwater stored in loose sediments in inland arid basins.The TDS indicates t he salinity of groundwater directly,and the variations of δ18O are ma inly influenced by evaporation.We can draw a line parallel to the evaporation li ne from each sample point on the TDS-δ18O relationship diagram.This parallel line will intersect the lixiviation line at c.The section a and b on both sides of c in the lixiviation line represent the contribution of lixiviation and evaporation to the sample's salinization respective.a=(TDS 3-TDS1-b)/(TDS3-TDS1)×100%，b=k(δ18O3-δ18O1)/(T DS3-TDS1)×100%. Applyng this method to analyze the groundwater salinizati on features in Taklimakan Desert,lixiviation is proved to be the main salinizati on process of groundwater though there is an arid climate and a high evaporation关键词
