| 摘 要： | 利用现有的国内外研究成果,分析土壤重金属与植物根伸长的相关性。根据含重金属土壤植物根伸长的生态毒性特性,将土壤重金属对植物根伸长抑制效应进行分级。按照不同土壤类型对土壤重金属质量的要求,对土壤重金属质量进行分级。利用土壤重金属对根伸长抑制率建立土壤重金属的评价标准,并与现有评价标准进行比较。结果表明,利用土壤重金属对根伸长抑制率建立土壤重金属的评价标准更能真实地反映土壤重金属的生物有效性。

| Abstract: | The correlation of heavy metals in soil and plant root elongation was analyzed based on present research results at home and abroad.According to the ecological toxicity characteristics of plant root elongation,the inhibition effect on plant root elongation was classified by soil containing heavy metal.According to different soil types of quality requirements for heavy metals,the quality of soil containing heavy metal was classified.Finally,the evaluation standard of soil containing heavy metals was established by using the inhibition ratio of root elongation compared with the existing evaluation standard. |
