湖北铜绿山铜矿区土壤铜污染状况及优势植物对铜的吸收

摘要

矿区重金属污染十分严重，寻找并筛选适合当地生长的优势植物成为推广矿区植物修复技术的前提。铜绿山矿区土壤重金属铜含量高，在矿区发现4种优势植物。通过测定植物根际土壤及植物各器官铜含量，得出在此4种植物对铜的积累与迁移特点，评估其在矿区土地恢复与植被重建方面的作用与价值。%The mining area of heavy metal pollution is very serious , searching and selecting advantage plants which are suitable for the local area becomes the premise of phytoremediation technology to promote mining area .The content of heavy metal Cu is high in soil from Tonglushan copper mining area . There were four advantaged plants found in the mining area . Through the determination of the Cu content in plant rhizosphere and in different organs , it is conclu-ded that accumulation and migration of Cu in the four plants , as-sessmenting their role and value in the mining area ’ s land and veg-etation recovery and rebuilding .
