为了解湘西花垣县兴银锰业周边土壤重金属污染状况及优势植物蓄积特征,采集了当地空心莲子草(Alternanthera philoxeroides )、窃衣(Torilis scabra )、商陆(Phytolacca acinosa Roxb.)、五月艾(Artemisia indica )、蒿草(Kobresia )、川莓(Rubus setchuenensis)等6种优势植物,根际土壤及5~10 m范围内未长植物的裸露土壤进行了研究。结果表明,研究区土壤主要存在Pb、 Zn、Cu、Mn、Cd等污染,土壤中Fe、Cr污染程度处于相对安全等级,裸露土壤单因子污染指数和内梅罗综合污染指数高于根际土壤;6种优势植物对重金属的富集量未超出临界值,对重金属具有较强的转运能力;植物根际土壤中真菌、细菌、放线菌...

In order to explore the situation of soil heavy metal pollution and the bioaccumulation characteristics of dominant plants around Huayuan Xingyin Manganese Industry in Xiangxi ,dominant plants such as A lternanthera philoxeroides ,Torilis scabra ,Phytolacca acinosa Roxb .,A rtemisia indica ,Kobresia ,Rubus setchuenensis ,rhizo-sphere soil and bare soil in the range of 5-10 m near the rhizosphere soil were researched .The results showed that Pb , Zn ,Cu ,Mn and Cd polluted the soil in the study area ,Fe and Cr pollution in the soil was at the relative safety level . The single factor pollution ...
