摘要
为丰富镉(Cd)超富集植物种质资源的筛选,促进植物修复技术研究,以现有文献报道的Cd超富集植物为基础,统计分析了Cd超富集植物的种类组成、区系分布特征及在中国的地理分布,并对后续Cd超富集植物的筛选及应用研究提出建议。结果表明,目前已筛选出的镉超富集植物共计80种,隶属29科69属,菊科植物种类占比最大,十字花科次之,有16种入侵植物。Cd超富集植物分布较广,具有从热带、亚热带向温带过渡的区系分布特点。就我国境内分布来看,Cd超富集植物主要分布于气候温和的地区,以西南地区分布最多。
The aim of this study is to enrich the selection of cadmium(Cd)hyperaccumulators germplasm resources and to strengthen the phytoremediation techniques research.Based on the existing literature on Cd hyperaccumulators,the species composition,floras characteristics and geographical distribution of Cd hyperaccumulators in China were analyzed,and then some suggestions were put forward for the selection and application of Cd hyperaccumulators.The results showed that there were 80 species of Cd hyperaccumulators,belonging to 29 families and 69 genera,16 species of them were invasive plants.Among them,compositae account for the largest proportion,followed by crucifer.The Cd hyperaccumulators were mostly cosmopolitan,diverse flora types and the most important flora type was the transition from tropical and subtropical to temperate zone.In terms of distribution in China,Cd hyperaccumulators are mainly distributed in temperate regions,with the largest distribution in southwest.
