重金属污染对土壤生态系统的影响及其修复技术研究

Research on Effects of Heavy Metal Pollution on Soil Ecosystem and its Remediation Technology

为了更好地改善土壤生态系统,本文首先阐述了重金属污染的四种类型及其对土壤生态系统的具体影响。然后结合土壤生态系统重金属污染的成因,提出了相应的修复技术,指出只有结合土壤生态系统的重金属污染原因以及污染程度,从工程修复技术、物理修复技术、化学修复技术、生物修复技术中选择出最合适的修复技术,才能有效解决土壤环境中的重金属污染问题,恢复土壤生态系统的功能与作用。

In order to better improve the soil ecosystem,this paper first expounds the four types of heavy metal pollution,and its specific impact on the soil ecosystem.Then combined with the causes of heavy metal pollution of soil ecosystem,gives the corresponding repair technology,points out that only combined with the cause of heavy metal pollution of soil ecosystem and pollution degree,from engineering repair technology,physical repair technology,chemical repair technology,biological repair technology to choose the most appropriate repair technology,to effectively solve the problem of heavy metal pollution in soil environment,restore the function and role of soil ecosystem.
