为寻找喀斯特地貌具有汞富集作用的优势植物，对贵州万山、务川、开阳主要汞矿区废弃地带的植物进行调查表明，采矿区与矿渣区共有17种植物，其中蜈蚣草、草等8种植物数量较多，均为20株以上；苍耳、蜈蚣草等6种植物地上部鲜重较多，均为100 g 以上；蜈蚣草、狗尾草等7种植物地上部汞含量较多，均高于1 mg/kg。狗尾草、蜈蚣草的汞富集系数较高。综合比较各项指标，蜈蚣草对于汞污染土壤的适应和富集具有一定的优势。

Plant species in abandoned lands of Wanshan,Wuchuan and Kaiyang mercury mines in Guizhou were investigated to seek dominant plants with mercury enrichment capacity in karst area.There are 17 plant species in mining area and slag area.The quantity of Pteris vittata ,Arthraxon hispidus and other six species is higher and more than 20 plants of each species can be found in a sample plot.The fresh weight of the aboveground part of Xanthium sibiricum ,Pteris vittata and other 4 species is above 100g. The mercury content of Pteris vittata 、Setaria viridis and other 5 species is above 1mg/kg.Setaria viridis and Pteris vittata are of higher mercury enrichment coefficient in 17 plant species.In conclusion,Pteris vittata has the good adaptability to soil polluted with mercury and higher mercury enrichment capacity according to integrated indexes.
