土壤退化是目前全球最严重的环境问题之一。而在当今提倡生态效益为重的前提下,生物改良措施已成为研究的热点。普遍认为生物改良措施是最具有生态效益、经济效益的措施,从宏观领域综述了土壤通过高聚物土壤改良剂在土壤改良中的应用,重点介绍了生物改良的研究进展,主要包括:植物对重金属污染土壤的改良、土壤动物对土壤的改良、土壤微生物对土壤的改良。又从微观领域研究了土壤—植物系统的磁生物效应及其微观机制。
Soil degradation is one of the most serious environmental problems in the world. However, under the premise of advocating ecological benefits today, biological improvement measures have become the hotspot of research. It is generally accepted that bioremediation measures are the most ecologically and economically beneficial measures. The application of soil amendments to soils through polymer soil amendments is reviewed from macro-level. The progress in bioremediation is highlighted, including: Improvement of heavy metal contaminated soils, improvement of soils by soil animals, and improvement of soils by soil microorganisms. From the microscopic field, we also studied the magnetism effect and its microscopic mechanism of soil-plant system.
