摘　　要：通过采样分析,研究了不同月份各采样点TSP质量浓度、同一时间各采样点TSP和PM10质量浓度,并对桂林市大气颗粒物中无机离子(Cl-、NO-3、SO2-4、K+、Na+、Ca2+、Mg2+、NH4+)进行定量分析测定。结果表明:桂林市大气颗粒物TSP质量浓度在11月要高于8月,3个监测点TSP日均值分别为0.2213,0.2775,0.1301 mg/m3;TSP与PM10质量浓度的相关系数为0.7406,PM10/TSP比值达到0.71以上,颗粒物构成基本相同。桂林市大气颗粒物中水溶性无机离子主要以SO2-4,Cl-,Ca2+,NH4+,Na+和K+为主,桂林市第八中学、八里街第一小学、建干路三采样点的无机离子组分状态大体相同,但存在个体差异。Samples of TSP and PM10 in the different months were collected,and the TSP and PM10 mass concentrations at the same time of each point had been studied. The inorganic ions of atmospheric particulates（ Cl^-、NO3^-、SO4^2-、K^＋、Na^＋、Ca^2 ＋、Mg^2 ＋、NH4^＋） in Guilin had been quantitatively analyzed and determined. Results showed that the atmospheric TSP concentration in Guilin was higher in November than in August,and the daily mean values of TSP at three sites were 0. 2213,0. 2775,0. 1301 mg / m^3,respectively; correlation coefficient of the mass concentration between the PM10 and the TSP was0. 7406,and the ratio of PM10 to TSP was up to 0. 71,indicating that the composition of the particulates were basically the same. The water-soluble inorganic ions in atmospheric particulate in Guilin were mainly SO4^2-,Cl^-,Ca^2 ＋,NH4^＋,Na＋and K^＋. The inorganic ionic components of the three sampling points,Guilin Eighth Middle School,the First Primary School in Eight Street and Jiangan Street,were roughly same,but existing individual differences.
