and typically have high heavy metal (such as Zn and Cd) accumulation capacities with fast growth rates and relatively high Pb tolerance in contaminated soils. We compared the accumulation characteristics of heavy metals in species through meta-analysis. Furthermore, we analyzed the effects of soil organic matter (SOM) and soil pH on Cd, Pb and Zn accumulation by and and the correlation between various metals. Results showed that the accumulations of Cd and Zn in shoots were higher than that of roots, but Pb accumulated in roots more than shoots. Moreover, there is a significant positive correlation between the accumulation of Zn and Cd in shoots. We found that the heavy metal accumulation rate in shoots was higher with lower soil pH. species had the highest Cd adsorption capacity in 20-30 g/kg SOM and the highest Zn adsorption capacity in SOM less than 20 g/kg. The accumulation rate of Cd in shoots of was increased with exposure time, while the accumulation rate of Zn was slightly decreased.
并且通常具有较高的重金属（如锌和镉）积累能力，生长速度快，在污染土壤中对铅具有相对较高的耐受性。我们通过荟萃分析比较了不同物种中重金属的积累特征。此外，我们分析了土壤有机质（SOM）和土壤pH值对某物种镉、铅和锌积累的影响以及各种金属之间的相关性。结果表明，地上部分镉和锌的积累量高于根部，但铅在根部的积累量多于地上部分。此外，地上部分锌和镉的积累之间存在显著正相关。我们发现，土壤pH值较低时，地上部分重金属积累率较高。某物种在土壤有机质含量为20 - 30 g/kg时镉吸附能力最高，在土壤有机质含量低于20 g/kg时锌吸附能力最高。某物种地上部分镉的积累率随暴露时间增加，而锌的积累率略有下降。
