| 摘 要： | 研究典型区域大气温室气体的变化有助于有效应对气候变化、减缓全球变暖和减少极端气候事件.选取1997-2018年瓦里关和2009-2015年上甸子温室气体月值数据，应用线性趋势分析法和Mann-Kendall突变检验法分析两站温室气体的时间序列特征、季节变化趋势，构建HYSPLIT后向轨迹模型分析季风运输和大气边界层条件对温室气体的潜在影响.瓦里关和上甸子温室气体均逐年增长，具有明显的季节变化特征.两站CO2均在8月达到最低值，CH4则在8月达到峰值，SF6四季差异不大.瓦里关N2O在12月达到最高，6月降到最低；而上甸子N2O在7月达到峰值，9月降至最低.瓦里关和上甸子大气温室气体均受到局地生物源和非生物源、季风远距离运输、大气边界层条件和光化学过程等多种因素的共同作用.

| Abstract: | Studying the changes of atmospheric greenhouse gases in typical regions will help effectively cope with climate change, slow global warming and reduce extreme climate events. In this paper, monthly data and the linear trend analysis method and Mann-Kendall mutation test method were used to analyze the characteristics of time series and seasonal variations of atmospheric greenhouse gases at Waliguan station during 1997-2018 and Shangdianzi station during 2009-2015. The HYSPLIT backward trajectory model was established to analyze the potential impacts of monsoon transportation and atmospheric boundary layer conditions on greenhouse gases. The greenhouse gases at both Waliguan and Shangdianzi stations significantly increased year by year, with obvious seasonal variations. Atmospheric CO2 at the two stations fell to the lowest in August, atmospheric CH4 reached peaks in August, and SF6 reached its maximum values in August and September, respectively. Atmospheric N2O at Waliguan station reached the highest in December and fell to the lowest in June, while atmospheric N2O at Shangdianzi station reached peaks in July and fell to its lowest in September. Atmospheric greenhouse gases at both Waliguan and Shangdianzi were affected by various factors such as local biological and non-biological sources, long-distance monsoon transportation, atmospheric boundary layer conditions and photochemical processes. |
