Abstract:

On the basis of expounding the concept and mechanism of soil biological degradation, this paper discusses the unavoidability of soil biological degradation and the significance of controlling it. The paper also compares the control measures of soil biological degradation with ecological restoration, puts forward measures for preventing and curing soil biological degradation, suggests to organize united task forces with multiple disciplines of plant protection, soil science, plant nutrition, soil microbiology, plant ecology and chemical ecology, according to the principles of restoration ecology. Studies on soil biological degradation from micro ecological restoration view point are carried out.

Key words: soil degradation, soil biological degradation, replant obstacle

摘要：

在阐述土壤生物退化概念和退化机理的基础上，论述了土壤生物退化的不可避免性和防治的重要性；比较了土壤生物退化治理与生态恢复；提出了土壤生物退化的防治措施；建议按照恢复生态学的原理组织植物保护学、土壤学、植物营养学、土壤微生物学、植物生态学及化学生态学多学科联合攻关，从微观生态恢复角度对土壤生物退化问题展开研究。
