摘要于2018年冬季（1月）和夏季（7月）在中国南方江西于都某偏远乡村采集PM_2.5样品，分析PM_2.5中BC浓度及其稳定碳同位素（δ¹³C_BC），水溶性离子浓度.结果表明，采样期间BC在冬季和夏季平均浓度分别为（1.3±0.8），（0.8±0.3）μg/m³，δ¹³C_BC在冬季和夏季平均值分别为（-25.8±1.6）‰和（-26.3±0.7）‰，两者整体呈现冬季高夏季低趋势，可能受到不同来源影响.相关性分析和贝叶斯模型源解析结果表明：冬季受生物质燃烧贡献最大为44.3%，其次机动车尾气和煤燃烧，分别为29.3%和26.4%；夏季受机动车尾气贡献最大为58.5%，其次生物质燃烧和煤燃烧，分别为28.8%和12.7%.后向轨迹表明，中国南方乡村的BC可能受到城市污染区域的长距离输送影响.

Abstract：In this study, PM_2.5 samples were collected in winter (January) and summer (July) 2018 at a remote site over the southern China. Black carbon (BC) concentrations of PM_2.5 and their stable carbon isotope (δ¹³C_BC) values, as well as water-soluble ion concentrations were analyzed. The results showed that the average concentrations of BC were (1.3±0.8) μg/m³and (0.8±0.3) μg/m³, while the average values of δ¹³C_BC were (-25.8±1.6)‰ and (-26.3±0.7)‰ in winter and summer respectively. Both BC concentrations and δ¹³C_BC showed high in winter and low in summer, suggesting that BC may be affected by different sources in different season. The results of Bayesian model showed that the fractional contributions of BC were 44.3% (28.8%) from biomass combustion, 29.3% (58.5%) from motor vehicle exhaust and 26.4% (12.7%) from coal combustion in winter(summer). The backward trajectories indicated that the BC in the background area of southern China may be affected by the long-distance transport from urban polluted areas.

Key words： PM_2.5 black carbon stable carbon isotope biomass burning nss-K⁺/BC
