摘要
大气降水氚浓度的研究不仅能提供重要的背景资料,而且能为运用同位素进行环境同位素科学以及与之相关的水文学、气象学和环境学科的研究提供一种有效的手段。以我国大气降水同位素监测数据(1985年—2002年)为基础,对单个站点、多个站点进行年际尺度的氚浓度的分析,讨论了氚浓度的时空变化的趋势及气象因素、地理要素的相关性。
The ratio of 1H content of precipitation will not only provide important background information,but also for the use of isotopes for environmental science and the associated isotope hydrology, meteorology and environmental disciplines. The analysis was conducted on monthly and annual mean 1H content of precipitation for spatial and a fixed location by using the data of China （1985--2002） in Global Network of Isotopes in Precipitation （GNIP） Database. The tritium concentrations of temporal and spatial changes in trends and meteorological factors, geographic factors were discussed.
