通过湖南花垣和苏仙两矿区野外踏查,数据检测Pb、Zn、Cu、Cd在两矿区相应植物土壤及植物中的含量及相关分析。结果表明:两矿区均受到Pb、Zn、Cd的污染。Pb元素在苏仙矿区是重污染,Zn对花垣矿区为中度污染,Cd对两矿区污染均为重污染,综合污染指数表明两矿区均为重污染。通过富集系数、转移系数、滞留率分析,发现14种优势植物表现出不同的吸收和富集特征,其中箬竹(Indocalamus tessella?tus)、油茶(Camellia oleifera)为富集型植物,菖蒲(Acorus calamus)、灯心草(Juncus effusus)、节节草(Equisetum ramosissimum)、毛萼莓(Rubus chroosepalus)、茅草(Imperata cylindrica)为根部囤积型植物,飞龙掌血(Todda?lia asiatica)为规避型植物。
通過湖南花垣和囌仙兩礦區野外踏查,數據檢測Pb、Zn、Cu、Cd在兩礦區相應植物土壤及植物中的含量及相關分析。結果錶明:兩礦區均受到Pb、Zn、Cd的汙染。Pb元素在囌仙礦區是重汙染,Zn對花垣礦區為中度汙染,Cd對兩礦區汙染均為重汙染,綜閤汙染指數錶明兩礦區均為重汙染。通過富集繫數、轉移繫數、滯留率分析,髮現14種優勢植物錶現齣不同的吸收和富集特徵,其中箬竹(Indocalamus tessella?tus)、油茶(Camellia oleifera)為富集型植物,菖蒲(Acorus calamus)、燈心草(Juncus effusus)、節節草(Equisetum ramosissimum)、毛萼莓(Rubus chroosepalus)、茅草(Imperata cylindrica)為根部囤積型植物,飛龍掌血(Todda?lia asiatica)為規避型植物。

The research and selection of dominant plants in mining area is an important approach to solve the soil heavy metal pollution repair. The samples are collected and investigated at the Huayuan and Suxian mining area in Hunan Province. 4 kinds of heavy metals (Pb、Zn、Cu、Cd) in soil and plants were analyzed in laboratory. The results showed that this two mining area were polluted mainly by Pb, Zn and Cd. And the Pb was heavy pollution in the Suxian mining area;The element Zn was moderate pollution in Huayuan mining area in Suxian mining area; the Cd was heavy pollution in Suxian and Huayuan mining area. The comprehensive pollution index shows that both mining area as heavy pollution. The heavy metal content were evaluated in plants of mining areas by enrichment coefficient,transfer coefficient and retention rate and the results showed that:14 kinds of dominant plants showed different absorption and accumulation characteristics,Indocalamus tessellatus and Camellia oleifera are enriched palnts,Acorus calamus,Juncus effuses,Equisetum ramosissi-mum,Rubus chroosepalus and Imperata cylindrica are root accumulation plant,Toddalia asiatica are avoid-ance type plant.
