| 摘 要： | 通过对南海腹地岛屿测站和南海北岸测站气溶胶样品中水溶性成分的分析，以及与华南大陆清洁测点和城市测点的对比，结果表明:海岛测点气溶胶总质量与诸离子浓度均大大低于海岸与大陆测点。其分布以三峰型出现的比较多，海岛与海岸气溶胶中水溶性成分以SO2-4，Cl-与Ca2+，Na+为含量比重最大的离子成分；与华南大陆测点相比，Cl-，Na+比重显著增加而NH+4的含量比重有所下降。

| Abstract: | An Andersen particle sampler (Model 20-709) is used for collecting and measuring atmospheric total aerosol samples over the South China and South China Sea during period from January 1988 to July1990. The mass distributfon of total aerosol and the distribution of water-soluble chlorine, nitric,sulphuric, sodium, ammonia, potassium,-calcium and magnesium ions have been analyzed. The resulitsshow that the concentrations of total aerosol and water-soluble composition in island stations are obvi viously lower than in seaboard stations and inland stations. Their size-distribution mostly exhibits atripeak distribution. The water-soluble sulphuric, chlorine, calcium and sodium ions in aerosols are hemost important ions composition islands and in seaboard stations. The concentration of water-solublechlorine and sodium ions in aerosols in the island and seaboard stations are obviously higher than in Inland stations of South China, but the concentration of ammonia ions is lower. |
