摘　　要：本文研究我国南北某些地区针叶林土壤中活性铝的形态分布,探讨了以羊毛铬菁R为显色剂测定活性铝的流动注射分析方法,并用四种化学浸提液作土壤中活性铝的溶出及形态分离。结果表明:土壤本身的酸度对铝的溶出和形态分布有明显影响。The active aluminum species on coniferous forest soils obtained from different districts in China was studied. Different species of active aluminum were leached respectively by four kinds of chemical extraction solutions and then determined by FIA method. Results show that the acidity of soil has siginificant effect on the content of aluminum leached and the aluminum species in soil.Investigation on the determination of aluminum by flow injection analysis was also made.
