摘　　要：为了提供讨论华南地区酸性降水形成机制的背景资料，１９８８年１月与８─９月，在广州、柳州、韶关、南宁、阳朔、龙门使用Ａｎｄｅｒｓｅｎ气溶胶分级采样器采集了分级气溶胶样品，并对水溶性的Ｆ－、Ｃｌ－、ＮＯ、ＳＯ、Ｎａ＋、ＮＨ、Ｋ＋、Ｃａ＋＋、Ｍｇ＋＋进行了分析，结果表明，在工业城市中粗粒态粒子显著多于清洁地区，工业城市气溶胶水溶性成分中的ＳＯ、ｃａ＋＋显著高于清洁地区，而Ｃｌ－有明显损耗。An Andersen particle sampler (Model 20-709) has been used for the collecting and measuring of atmospheric total aerosol samples at Guangzhou,Liuzhou,Shaoguan,Nanning,Yangshuo and Longmen in South China during the winter and summer in 1988.The mass distributions of total aerosol and the distributions of fluorine,chlorine,nitric,sulphuric,sodium,ammonia,potassium,calcium,magnesium ions of water soluble have been analyzed.The results show that the coarse particles are obviously higher in industrial cities than those in clean regions.The sulphuric and calcium ions of water soluble of aerosols are obviously higher in industrial cities than those in clean regions, and chlorine ionsis markedly loss.
