| 英文摘要 | A total of 117 water samples, including cave water, ground water, spring water and river water, collected from the monsoonal area of China have been analyzed for their H- and O-isotope composition. Overall, a delta(18)O-delta D correlation is observed of delta D = -4.45 + 6.6 delta(18)O (R(2) = 0.90) and a significant evaporation effect observed for the southern sites. Average delta(18)O and delta D site values generally correspond to those of precipitation in nearby cities, with correlations of delta D = 2.18 + 7.23 delta(18)O (R(2) = 0.95) for the sample sites and delta D = 11.05 + 7.95 delta(18)O (R(2) = 0.95) for the cities. The effects of rainfall amount and temperature on precipitation delta(18)O were calculated using a simplified theoretical model derived from the Rayleigh distillation equation, which demonstrated that the sign of delta(18)O(P) vs. T correlation is dependent on precipitation intensity. The mean delta(18)O value of cave waters exhibit decreasing trends with increasing latitude and reveal a spatial pattern of positive correlation with annual mean temperature and precipitation, mainly reflecting isotopic fractionations in the moisture source traveling from the ocean side to the inland continent. This spatial pattern implies that the delta(18)O values recorded in the proxy climate records derived from speleothems might be influenced by shifts in monsoon boundary during the past, especially between glacial and interglacial intervals.
