摘要/Abstract

摘要： 通过测定土壤样品的重金属含量,调查了上海七宝镇污染水系两侧与上海宝钢集团厂区的重金属污染状况.结果表明,在污染水系两侧重金属含量较对照稍高,而上海宝钢厂区各样点土壤重金属含量明显高于对照,存在较严重的污染.同时在这两处重金属污染地带观察记录了绿化树种的生长状况,采集植物样品以ICP仪进行树木样品的重金属含量分析,综合两方面数据对近20种常见绿化树种的重金属污染的防护特性进行了比较研究.结果表明,法国冬青、紫薇、木芙蓉、女贞和龙柏等植物种类富集重金属能力较强,且生长状况较为良好,最适于作为重金属污染厂区的生态防护绿化的主要树种;而蚊母、夹竹桃和石楠等植物种类虽然富集重金属能力较低,但有较强的耐性,能良好生长,也适于作为污染区绿化美化树种.

关键词: 重金属, 污染防护, 绿化树种

Abstract: In this paper,the stream banks nearby Qibao town and the factory area of Shanghai Baoshan Steel Company were selected as the typical areas contaminated by heavy metals.The polluted status was investigated by measuring the heavy metal concentrations of the sampled soils.The results showed that the heavy metal concentrations in the soils of stream banks were a little higher than the control,but obviously higher in the factory area of Shanghai Baoshan Steel Company.The growth status of the greening trees was recorded,and their heavy metal concentrations were measured by ICP.According to the research results and historic data,the excellent greening tree species mainly applied in polluted factory area were Viburnum awabuki,Lagerstroemia indica,Hibiscus mutabilis,Ligustrum lucidum and Sabina chinensis,which could grow well on contaminated soil,and accumulate high concentrations of heavy metal elements.The other tree species such as Distylium racemosum,Nerium indicum,and Photinia serrulata might be also available in greening for heavy metal pollution protection.

Key words: Heavy metal, Pollution protection, Greening tree species
