摘要利用2009~2019年阿克达拉国家大气本底站CH₄浓度数据、气象要素数据，使用随机森林模型、后向轨迹模型聚类分析方法对其CH₄浓度变化特征和影响因素进行分析.结果表明，10a间阿克达拉站CH₄浓度增长明显，年平均浓度为（1934.30±30.94）×10^-9，平均增长率0.45%；季节变化呈现秋冬高、春夏低的特征，冬季（1973.77±36.72）×10^-9>秋季（1935.86±36.14）×10^-9>春季（1922.36±26.38）×10^-9>夏季（1920.92±29.82）×10^-9.阿克达拉站CH₄浓度受到气象因素综合影响，气温和相对湿度占主导作用.基于HYSPLIT模式和全球资料同化系统气象数据（GDAS）后向轨迹聚类分析发现，阿克达拉站气团移动的主要通道是与额尔齐斯河河谷平行，途径阿拉山口和老风口的西北路径，且秋冬季节气团移动速度慢、春夏快，可能影响了CH₄浓度季节变化.

Abstract：The observation data of CH₄ concentrations and meteorological elements of Akedala station from 2009 to 2019 were used to analyze the CH₄ concentration changes and influencing factors using random forest model and backward trajectory model with clustering analysis methods. The results showed that the CH₄ concentrations at Akedala station increased significantly during the recent 10yaers with an annual average concentration of (1934.30±30.94)×10^-9 and an average growth rate of 0.45%. The seasonal changes showed high CH₄ in autumn and winter and low CH₄ in spring and summer, with winter (1973.77±36.72)×10^-9>autumn (1935.86±36.14)×10^-9>spring (1922.36±26.38)×10^-9>summer (1920.92±29.82)×10^-9. The CH₄ concentration change at Akedala station is influenced by a combination of meteorological factors, with air temperature and relative humidity playing the dominant roles. Backward trajectory clustering analysis based on HYSPLIT model driven by GDAS meteorological data reveals that air mass movement to Akedala station is mostly along the northwestern path paralleling to the Valley of Erchez River, and passing through Alashankou and Old Wind Pass. In addition, the low movement speed in autumn and winter as well as its high speed in spring and summer could affect the seasonal variation of CH₄ concentrations.
