Based on the evaluation system, the plants whose relative remediation age was between 0~10 years were named as"Hyperaccumulator"and those between 10 ~ 50 years were named as"Accumulator".7 In the experiments six kinds of substrates were mixed with different solid wastes and the absorption and enrichment of plants on heavy metal Cd was studied. The results showed that relative remediation age was an ideal index to evaluate the capability of the phytoremediation on heavy metals, because it took into account more factors which affected the absorption evaluation effects than others, such as the heavy metal content and the biomass of the over-ground part of plants, the heavy metal content and the whole gross in substrates, harvesting frequency of plants and the environment standard of heavy metal. This made relative remediation age be suitable to the sorption capability evaluation of not only different plants on one heavy metal but also one plant on different heavy metals.8 It can be drawn from the relative remediation age of heavy metal Cd that the absorption capability of different plants was not same.

以相对修复年限为评价指标定义相对修复年限为0-10年的植物为"超富集植物"，10-50年的植物为"富集植物"。7在由不同废弃物按一定的比例混合配制的六种土地复垦基质上，系统地研究了几种植物对重金属镉的吸收和富集情况，结果表明，相对修复年限既适用于不同植物对同一种重金属元素的吸收能力的评价，又适用于同一植物对不同重金属元素的吸收能力的评价，是衡量重金属元素植物修复效果的理想指标。8从不同植物对同一基质重金属镉的吸收和富集能力看，不论是经过多年种植的基质，还是第一次种植的基质，小白菜和油菜都是相对理想的植物；而黑麦草、高羊茅和苜蓿的吸收效果并不理想。
