| 摘 要： | 采用热转换元素分析同位素比值质谱法(TC/EA-IRMS)对重庆至上海段长江干流的氢氧同位素进行了监测,分析了该段长江水的氢氧同位素和氘过量参数的空间变化规律,并探讨了δ(18O)和δ(D)与大气降水氢氧同位素的关系.结果表明:长江干流不同地段水体受补给来源、大陆效应、高程效应等因素影响,其水体氢氧同位素也呈现出不同的...

| Abstract: | This paper analyses the spatial variation characteristics of hydrogen and oxygen isotopes and deuterium excess parameters,and studies the relationship of hydrogen and oxygen isotopes between water of Yangtze River and of precipitation based on the data of hydrogen and oxygen isotopes of Yangtze River from Chongqing to Shanghai.The results show that hydrogen and oxygen isotopes present different characteristics along Yangtze River due to influences of water recharge sources,continental effect and altitude ef... |
