中文摘要	对南京市城区与郊区秋季PM_(10)中水溶性离子的浓度水平,变化规律及其相关性进行分析。结果表明:水溶性离子是南京市PM_(10)的重要组成部分,占PM_(10)总量的26.8%~49.5%;NO3-、SO24-为南京PM_(10)中离子的主要成分同时SO_4~2-与PM_(10)的相关性高,在郊区与城区相关系数分别为0.97与0.98;土壤源对Mg~(2+)的贡献多于海洋气溶胶。郊区与城区非海盐Mg~(2+)和Ca~(2+)的比值分别为0.0308~0.0557与0.0314~0.0558,与中国北方沙漠地区相异,说明观测期间南京大气PM_(10)主要受局地源影响;南京城、郊NO_3~-/SO_4~(2-)均值分别为0.74和0.80,说明南京市城郊PM_(10)中NO_3~-与SO_4~(2-)更多地来自于机动车尾气排放。
英文摘要	It was researched that the concentration level,change law and correlativity of the water soluble ions in PM_(10) in autumn in the urbon and suburban areas of Nanjing.The results showed that water soluble ions were an important part of PM_(10) in Nanjing,which accounted for 26.8% to 49.5% of PM_(10) total amount;NO_3~-,SO_4~(2-) were the main component of PM10 in Nanjing while the correlation between SO_4~(2-) and PM_(10) was high,in suburban and urban areas correlation coefficients were 0.97 and 0.98;the soil source contribution to Mg~(2+) was more than marine aerosols.Suburban and urban non-sea salt Mg~(2+)/Ca~(2+) ratios were 0.0308~0.0557 and 0.0314~0.0558,which were different from desert regions of northern China,showing that PM_(10) is mainly affected by local source;suburban and urban NO_3~-/SO_4~(2-) ratios(average) were 0.74 and 0.80,showing that NO_3~- and SO_4~(2-) in PM_(10) in Nanjing were mainly from vehicle exhaust emissions.
