摘　　要：生物富集是指生物体从周围介质中吸收、积累某种元素或难以降解的物质,使其在生物体内浓度超过环境浓度的现象。本文介绍了植物对土壤重金属富集的生理机制及其应用研究,以期为生物富集相关内容的教学提供参考信息。Bio-concentration refers to the phenomenon in which organisms absorb and store certain elements or indigestible substances from the surrounding environment,resulting in a concentration in the body exceeding that in the environment.In this paper,the physiological mechanism and practical applications of plants on soil heavy metals enrichment were introduced,in order to provide reference for the teaching of bio-concentration.

关 键 词：生物富集 重金属 超富集植物
