摘　　要：Fluoride contents in plants and soils in Kaili City were measured with fluorinion as per electrode method and the related characteristics were analyzed in order to explore effects of air fluoride pollution on plant and soil.The results indicated that fluoride content in plants tended to be volatile in 135.62-1 420.97 μg/g and averaged 513.99 μg/g;fluoride content in soils changed from 240.50-340.36 μg/g and averaged 279.60 μg/g.The contents of plant and soil both exceeded background value,suggesting that plants and soils in the region have been polluted.In addition,fluoride contents differ significantly upon plants.In detail,the maximal content was in Camelliaolelfera Abel and the minimal in Camelliaolelfera Abel.The contents of fluoride in different plant species vary,as follows：shrub vine herbaceous plant arbor;evergreen plants deciduous plant;fluoride contents in plants and soils also differ in varying degrees upon research sites.为了解大气氟污染对植物、土壤的影响,采用氟离子选择电极法对凯里的植物和土壤的氟含量进行了测定,并对其特征进行了分析。结果表明:该区植物的氟含量在135.62～1420.97μg/g之间,平均含量为513.99μg/g;土壤氟含量在240.50～340.36μg/g之间,平均含量为279.60μg/g。植物、土壤的氟含量都超过了背景值,该区植物和土壤都受到了不同程度的氟污染。不同植物的氟含量存在较大差异,油茶的氟含量最高,马尾松的氟含量最低。不同类型植物的氟含量不同,灌木>藤本>草本>乔木;常绿植物>落叶植物。不同研究点植物和土壤的氟含量存在差异,但有些植物差异较大,有些差异不明显。
