基于重金属对土壤动物多样性影响评价土壤重金属的研究

Study of Evaluation Standard of Heavy Metals in Soil Based on Inhibition Effect of Soil Animal Diversity

利用国内外研究成果,分析了土壤重金属与土壤动物多样性抑制率的相关性。根据含重金属土壤动物多样性的生态毒性特性,将土壤重金属对土壤动物多样性抑制效应进行了分级,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。利用土壤重金属对土壤动物多样性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了比较,结果表明:利用土壤重金属对土壤动物多样性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生物有效性。

This study analyses the correlation of heavy metals in soil and the diversity of soil animal with present research results at home and abroad. According to the ecological toxicity characteristics of soil animal, the inhibition effect on soil animal is classified by soil containing heavy metal. According to different soil types of quality requirements for heavy metals,the quality of soil containing heavy metal is classified. Finally, the evaluation standard of soil containing heavy metals is established by using the inhibition ratio of soil animal and it is compared with the existing evaluation standard.
