摘　　要：通过探讨福建省平和县钟腾、泮池、鸡笼山、大芹山4个主要矿区内地球化学元素在岩-土-植被中的迁移规律,以期为该区植物地球化学找矿提供依据。研究表明,土壤中主要金属元素及稀土元素REE的分配规律在垂向上与岩石具有一致性;植物对元素种类的吸收具有选择性,Zn在该区植物中显示强积聚的特征,Co、Ni、Cu属一般积聚型元素,Bi、Mo、As是弱积聚型元素。毛蕨和夹竹桃对稀土元素REE的富集十分明显,超过平均含量达千倍以上。初步判断毛蕨、夹竹桃对在研究区内寻找铜钼矿具有一定的指示意义。This study explored the migration regularities of geochemical elements in rocks-soil-plants from the Zhongteng, Panchi, Jilongshan and Daqinshan Cu-Mo districts in Pinghe County, Fujian Province, aiming to provide evidence for the botanogechemical ex- ploration in this region. It is shown that the distribution of the main metal elements and REE is consistent with that in rocks vertically. The plants absorb elements selectively： the element Zn is strongly enriched in the plants of this area, the elements Co, No and Cu are generally enriched, and the elements Bi, Mo and As are weakly enriched. It is obvious that Cyclosorus and Nerium are highly enriched in REE, about more than one thousand times of the average content. Therefore, Cyclosorus and Nerium can be considered as indicator plants for the copper-molybdenum mineralization in this area.
