摘要

基于稳定同位素质量平衡及水量平衡

推导了内陆湖泊稳定同位素模型

结合羊卓雍错氧同位素数据计算了羊卓雍错湖水渗漏量。讨论了湿度因子、温度因子对湖泊渗漏量的影响。结果表明

在其他影响因子不变条件下

渗漏量所占比重越大

湖水δ18O值越负。羊卓雍错湖每年的渗漏量达到补给量的30.6%。

Abstract

Based on stable isotopic mass balance and water balance

a stable isotopic model is built. According to the measured stable isotopic data and relevant hydro meteorological data of the Yamzho Lake

the mean leakage is calculated by the stable isotopic model. Factors affecting the lake water leakage are discussed

too. If the factors do not change

the δ18O depletes more with the water leakage. The result shows that leakage is 30.6% of the recharge rate. The model has some guidance significance to study stable isotope variation of inland lake.
