摘要:
为了探明达里诺尔湖流域地表水与地下水的氢(H)、氧(O)同位素的变化特征及相互补给关系,于2013年对达里诺尔湖及其周围的河水、井水、泉水中H、O同位素进行了取样分析,并结合总溶解性固体悬浮物(TDS)和区域水文地质对达里诺尔湖流域的补给关系进行讨论分析.结果表明:1) 河水、泉水、井水中H、O同位素的值基本落在全球雨水线上,湖水H、O同位素落在全球雨水线的右下方,说明河水、井水、泉水没有发生蒸发分馏,而湖水则发生较大程度的蒸发分馏;对达里诺尔湖流域地表水与地下水的H、O同位素进行回归模拟,得出该区域的蒸发趋势线方程:δD=4.8753 δ18O-20.139(n=32,R2=0.9968).蒸发线表明,这些水样具有相同水源的特征.2) 从实地考察发现,泉水补给河水,泉水和河水补给湖水,同时井水、泉水和河水有相似的δD、δ18O和TDS值,且不随季节变化而变化,推断达里诺尔湖附近地下水补给湖水;区域水文地质条件亦证明达里诺尔湖周边地下水补给湖水.

Abstract:
To examine the characteristics of hydrogen and oxygen isotopes change in surface water and groundwater and their relationships of discharge and recharge in the Lake Dali basin, the hydrogen and oxygen isotopes were detected from the water samples of rivers, wells and springs around the Lake Dali in 2013. The discharge-recharge relationship in the Lake Dali basin was analyzed with regional hydrogeology and total dissolved solids(TDS) of the lake. The results showed that 1) the values of hydrogen and oxygen isotopes in the rivers, springs and wells are all on the globe rainfall lines, while those in the lake are at the right below the globe rainfall line. It means there was no evaporation in the rivers, wells and springs, but a larger evaporation in the lake. The regression analysis of groundwater and lake water of the Lake Dali basin was performed and the regional evaporation equation is δD=4.8753 δ18O-20.139(n=32, R2=0.9968). The evaporation equation showed that the water samples have the characteristics of identical water source. 2) It is observed that springs recharge rivers and both of them recharge lake. Meanwhile, springs, rivers and lake have the similar values of δD, δ18O and TDS, and the values do not change with seasons. It can conclude that the groundwater around Lake Dali recharges the lake, and it is also proved with regional hydrogeological conditions.
Key words:  Hydrogen and oxygen isotopes  total dissolved solids  groundwater  surface water  recharge relationship  Lake Dali
