应用原子吸收法对九台营城煤矿废弃地修复前后土壤中五种重金属元素(Cu、Ni、Pb、Cd、Zn)含量进行了测定,并利用内梅罗综合污染指数法评价其重金属污染强度,比较了三种牧草(黄花草木樨, Melilotus suaveolens；紫花苜蓿,Medicago sativa；白花三叶草,Trifolium repens)的适应能力、修复效应及富集特征。结果表明,引进品种黄花草木樨“斯列金1号”修复效应较好,适应能力较强,种植两年后土壤由重度污染降为轻度污染,污染严重的镉(Cd)降为中度污染,生物量增长较大,其次是紫花苜蓿,白花三叶草不能生长；黄花草木樨、紫花苜蓿对5种重金属的富集转移规律不尽相同,且随着种植时间的变化而变化,其中黄花草木樨的富集能力及转移能力均大于紫花苜蓿,并随着种植时间的延长而增强,对五种重金属元素中镉(Cd)、铜(Cu)的富集能力和转移能力较强；紫花苜蓿的富集能力和转移能力随着种植时间的延长而降低,其对Cd的富集能力较强,种植第一年对Pb转移能力强,种植第二年对Cu的转移能力较强。

Atomic absorption spectrometry was used to determine the concentration of five heavy metals (Cu, Ni, Pb, Cd, Zn) in Yingcheng coal mine restoration in Jiutai City. Nemerow pollution index method was selected to evaluate the heavy metal pollution intensity. The repair effects and accumulation characteristics of three forage (ME-Melilotus suaveolens; MS-Medicago sativa;TR-Trifolium repens) were compared. The results showed that repair effects of MS was the best transforming the heavily polluted soil pollution to light by planting two years. The transfer rule of heavy metal enrichment was different between ME and MS changed through planting period. The total average enrichment capabilities and metastasis of ME were higher than that of MS. The enrichment ability of MS was high in Cd, whose ability of transforming was higher in Pb and Cu in two planting periods.
