摘要：

通过分析2006年8月～2009年7月临安区域大气本底站Flask瓶采样获得的CH4浓度特征，结合地面风向、后向轨迹、排放清单，研究了CH4浓度变化特征和长三角地区排放源对CH4浓度的影响作用。结果表明，临安区域大气本底站的CH4浓度分布在1 7584×10-9~1 9700×10-9，具有较明显的季节波动变化特征，浓度季节变化幅度为737×10-9；CH4浓度平均年增幅达176×10-9，增速较快。东北风和东南风时，CH4浓度较高；西南风时CH4浓度较低。导致CH4高浓度分布的气团主要来自临安站的东北、偏东方向；导致CH4低浓度分布的气团集中在西南偏南

Abstract:

Characteristics of atmospheric CH4 concentration obtained by Flask measurements were analyzed at Lin'an regional background station from August 2006 to July 2009.According to the wind direction,backward trajectories and emission inventory,the variation characteristics of CH4 concentration was studied and the impact of emission sources on CH4 concentration was evaluated in Yangtze River Delta.The results revealed that atmospheric CH4 concentrations at Lin'an regional background station were between 1 7584×10-9 and 19700×10-9.The CH4 concentration varied as seasons change and the annual difference was about 737×10-9.The longterm trend of CH4 concentration showed rapid growth year by year;the average growth rate was about 176×10-9/a.The CH4 concentrations were high when the winds were from the northeast and southeast,and the CH4 concentrations were low when the winds were from southwest.The air mass contained high CH4 concentrations mainly came from the northeast and east sector while the air mass contained low CH4 concentrations almost came from the southwest and south sector
