| 摘 要： | 依据国际原子能机构(IAEA)提供的天津地区1988~2001月降雨和同位素资料,分析了该地区大气降水的稳定同位素的组成和变化以及主要影响因素.天津大气降水线与我国东部季风区的局地大气降水线方程较为接近.大气降水同位素组成变化中的温度和降水效应较小,主要受季风以及季节水汽来源不同的影响,有显著的季节效应.

| Abstract: | According to the isotope and precipitation data of 1988 - 2001 in Tianjin area from the IAEA, the composition and distribution in the area of stable isotopes of precipitation and the main factors were analyzed. The local meteoric water line was in line with the eastern monsoon region meteoric water line in China. The temperature and precipitation was not very striking by the changes of isotopic composition of precipitation, the monsoon and moisture from different sources in different season are the mainly factors, and seasonal factors are very significant. |
