| 摘 要： | 中d小,受沿途降水冲刷作用的影响,降水中稳定同位素比率较低;在旱季,受大陆性气团的影响,我国西南地区降水的水汽主要来源于西风带的输送和内陆再蒸发水汽的补给,空气湿度小,降水中稳定同位素比率和d较大. |
| 关 键 词： | 西南地区 降水 稳定同位素 过量氘 水汽来源 |

| Abstract: | In order to reveal the vapor origins of precipitation over Southwest China,the variations of stable isotopes including deuterium excess d and the relationships of the stable isotopes with temperature and humidity at Mengzi and Tengchong sampling stations are analyzed.Under the monsoon system,d in precipitation has distinct seasonality with lower values in the rainy season and higher values in the dry season.Analyses show that the relationship of d in precipitation with temperature and humidity in the middle... |
