对闽东、闽北和闽南茶区典型剖面的各层土样及相应的茶树植株进行地球化学研究．结果表明，茶区土壤全氟含量均值２３７±５５ ｇｇ－１，处于世界与我国土壤含氟量的偏低水平；闽北茶区显著高于闽东与闽南茶区。而闽南土壤水溶氟却略高于闽北和闽东。氟在红壤的含量与土壤中的铝、钛、锰等元素呈显著正相关，而与硅、镁、钾、钠等元素呈显著负相关。土壤全氟和水溶氟含量，呈现一个完整的淋溶──堆积系列，丘陵坡地的紫色土含氟量向一阶地的潮土增加的明显趋势。
Soil samples from the typical sections of the eastern Fujian, northern Fujian and southern Fujian tea regions and the corresponding tea plants were studied geochemically. The results showed that the average soil total fluorine content in the tea area was 237 ± 55 gg-1, which was lower than that of the soil in our country. The tea area in northern Fujian was significantly higher than that in the eastern and southern Fujian tea regions. However, the water solubility of Fujian southern soil was slightly higher than that of northern Fujian and eastern Fujian. The contents of fluoride in red soil were positively correlated with elements such as aluminum, titanium and manganese in soil, but negatively correlated with elements such as silicon, magnesium, potassium and sodium. Soil perfluorinated and water-soluble fluorine content, showing a complete leaching ─ ─ accumulation series, purple soil slope hilly slope to a trend of the first trend of the trend of the Chao soil.
