蚯蚓与重金属污染治理及蚓粪应用的研究进展

Recent developments of earthworm in heavy metal contamination treatment and application of vermicompost

论述了蚯蚓作为一种十分有益的腐殖性土壤动物 ,在土壤生态系统腐屑食物网中所占有的重要地位 ,探讨了蚯蚓能够通过生态链的放大作用富集重金属元素 ,在重金属污染区的土壤改造和生态恢复中发挥的巨大作用 ,并可以作为重金属污染区污染程度的监测生物 .进而提出了蚯蚓参与土壤有机质的分解 ,在正常的代谢过程中所产生的蚓粪所具有的重要生态和经济利用价值 .并论述了国内外目前在这两方面的研究进展 .

Earthworm, as a very beneficial soil fauna, play significant roles in the detritus food webs of soil ecosystem. For one thing, earthworm can concentrate heavy metals through ecosystem, so in the contaminated area, earthworm can be used as monitor of metal contamination degree and play significant roles in ecological restoration. For another, the vermicompost, they produced in normal metabolism, have great value in ecosystem and economy. The article mainly introduces the latest research result about the two aspects mentioned above.
