Abstract:

根据2010年在长沙地区所收集的降水、河水、泉水和井水水样资料,分析了取样期间不同水样稳定同位素的变化特征,并结合湘江长沙段水位和相关气象资料,揭示了降水中δ18O、δD因水汽来源不同而其表现出冬半年高、夏半年低的特点;由于降水降落于地表后,地表对降水滞留作用而使得河水、泉水和井水中δ18O、δD的波动幅度明显小于降水中δ18O的波动幅度;在汛期,河水中δ18O算术平均值大于降水,在枯水期河水中δ18O比泉水和井水中δ18O要大;河水线(RWL)的斜率和截距与全球大气水线(GMWL)比较接近,说明该地区位于季风区河流的补给主要来自大气降水,井水线(WWL)的斜率和截距比泉水线(SWL)要小,这表明降水入渗形成井水过程中经历的蒸发作用要比形成泉水要强,井水补给比泉水补给要复杂。这为今后研究该地区地表水-地下水-大气降水之间转换关系提供了科学依据,对掌握“三水”间转换规律和合理开发利用水资源具有重要的意义。
