摘要
对中国东部从广西板八(北纬21.70°)至黑龙江五大莲池(北纬48.80°)之间采集的42个大气降水样品进行了H、O同位素组成研究,并讨论了其纬度效应和高度效应等。
δ18O and δD values for 42 meteoric water samples were analyzed. It can be seen that both δ18O and δD values vary synchronously with latitude along our investigation-tour route from Guangxi (22.7 NL°) to Heilongjiang(48.8 NL°). Their relationship is presented as follows: δ18O() = - 0.24NL°+ 0.04 andδD(‰) = - 1.84NL° + 6.88. The relationship between δ18O, δD and altitude in the southeastern part of the Guizhou Plateau is: - δ18O(‰) = 0.003H(m) + 5.24 and - δD(‰) = 0.0134H(m) + 39.8.
