土壤修复与改良利用的生物技术研究进展

Advances in Biotechnology Research on Soil Remediation and Improvement

随着工业的快速发展,我国的环境污染日益严重,尤其是土壤污染及退化,治理土壤污染和退化的工作越发受到重视。本文针对土壤重金属污染、土壤有机物污染和土壤盐碱地等问题,提出了生物修复技术,综述了其研究进展,明确土壤生物修复技术与盐碱地改良存在的技术难点,展望土壤污染治理新技术的研究前景,为改善土壤环境、增强土壤可持续利用提供理论依据。

In recent years, soil pollution and degradation were increasingly becoming an important environ-mental problem. The research on the restoration and improvement of soil pollution is being paid more and more attention. In order to improve the soil environment and enhance the ability of the sustainable use of soil, biological technology is a new technology for soil treatment. This paper mainly summarizes the bioremediation of soil heavy metal pollution, soil organic pollution and soil salinization, including phytoremediation and improvement, microbial remediation and utilization. At the same time, the problems existed in soil bioremediation technology and improvement technology were reviewed. In the future, the development trend of biotechnology of soil treatment is prospected.
