中文摘要	对来自 GNIP 的我国和印度8个站点的加权平均年大气降水氧同位素(delta~(18)O_p)和年降水量数据进行的线性相关分析结果表明: 我国华南地区的 delta~(18)O_p与降水量的关系不显著, 说明用该区域相关的古记录来指示降水量的变化, 其价值和意义是有限的; 印度季风区4个站点的 delta~(18)O_p与年降水量之间普遍更显著的负相关关系, 说明印度季风区 delta~(18)O_p变化很可能受控于年际尺度的降水量效应, 印度夏季风强度变化可能通过瑞利分馏效应对东亚季风区 delta~(18)O_p产生重要影响.
英文摘要	In the present study, linear correlations between weighted-average annual precipitation oxygen isotopes (delta~(18)O_p) and annual precipitation amount (original data from five Chinese and three Indian GNIP stations, respectively) demonstrated that: 1) correlation between delta~(18)O_p and annual precipitation amount is insignificant in southern China, so the significance of relevant geological proxy records as indicators of variations in past precipitation amount is limited in this area; 2) overall, negative correlations between delta~(18)O_p and annual precipitation amount at the four stations in the Indian monsoon region are much more significant than those for the four stations in the East Asian monsoon region. This indicates that delta~(18)O_p in the Indian monsoon region is probably controlled by an interannual amount effect, and delta~(18)O_p in the East Asian monsoon region may be strongly influenced by variations in Indian summer monsoon intensity via the Raleigh fractionation effect.
