Аннотация:42 meteoric water samples were analyzed for their δ18O and δD values. 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(‰)=−0.24 NL° + 0.04 and δD(‰)=−1.84 NL° + 6.88. The relationship between δ18O, δD and altitude in the southeastern part of the Guizhou Plateau is: $$ - \delta ^{1{\rm B}} O(\% o) = 0.003H(m) + 5.24 and - \delta D(\% o) = 0.0134H(m) + 39.8.$$
