| 摘 要： | 于2012年4月沿大九湖湿地平均分布10个采样点，各采集0~10、10~20以及20~30 cm浅层土壤，采用GC-MS对大九湖湿地浅层土壤中USEPA 16种优控多环芳烃（PAHs）进行分析，对其分布、组成、来源进行了详细的讨论，并对高山湿地PAHs污染标志物进行了浅析.结果表明，研究区0~10、10~20、20~30cm浅层土壤中∑16PAHs含量分别为48.55~984.73、14.36~806.47、12.84~1191.53 ng·g-1，均值分别为302.94、142.98、208.68 ng·g-1；7种致癌单体多环芳烃含量范围分别为21.20~844.29、2.96~592.06、0.66~964.70 ng·g-1，均值分别为197.25、93.16、147.16 ng·g-1，分别占总PAHs的65.12%、65.13%、69.08%；泥炭区PAHs含量明显高于非泥炭区，且已达到重度污染程度；PAHs组成以4、5、6环为主；结合IcdP/（IcdP+BghiP）及Pyr/BaP比值分析，推测大九湖湿地浅层土壤中PAHs主要来源于化石燃料及木材的燃烧，近年来旅游车辆的进入对PAHs的贡献较大；对浅层土壤中各单体PAH与PAHs总含量进行回归分析表明、苯并（b）荧蒽、茚（1，2，3cd）并芘、苯并（a）蒽作为泥炭地PAHs标志性化合物，用来评价PAHs的污染程度.
