摘要
在研究总结植物修复技术进展现状基础上,以株洲某工业区土壤及植物重金属含量数据为对象,分析在该区筛选重金属超累积植物及开展土壤重金属污染的植物修复工作的可能性。据研究区植物重金属含量分布规律,认为该区可筛选出Cd等元素的超积累植物;据植物生物量估算,认为以菊芋等植物组合并辅以施肥等强化措施,可进行土壤重金属污染的植物修复。
This paper reviews the progress and status of phytoremediation and conducts a research on the identifi- cations of the plants that? hyper - accumulate contaminants? of heavy metals in the soil and makes a feasibility study on the cleaning up of contaminants in the soil using phytoremediation, based on the analysis of the data of heavy metal contents in the soil and plants in a Zhuzhou Industrial Zone. On the basis of the distribution of heavy metal contents in the plants of the area under the research, this paper identifies the plants that hyper - accumulate contaminants such as Cd. In accordance with the estimation of plant biomass, the paper proposes that a combination of Jerusalem artichoke and some other plants, together with strong measures such as fertilization, can be used to clean up the soil contaminated by heavy metals.
