摘要
土壤微生物是土壤亚生态系统的重要组成成分,它们在土壤的养分和物质循环、形成和发育、肥力维持与提高的过程中起着重要的作用,但其本身的群落结构与功能极易受土壤、水分、温度、植被、污染物质的影响。本文综述各种环境条件变化对土壤微生物产生影响的研究进展,以期促进对土壤微生物与土壤健康关系的研究。
Soil microbe, an indicator of soil health, plays an important role in nutrient cycling as well as in soil formation and development and soil fertility maintenance and improvement. However, the soil microbe is sensitive to any chan ges in soil environment and related human activity. The present paper reviews im pacts of soil environmental variations on soil microbe activity and population d ynamics with a view to encouraging researches and management practices on soil m icrobe health and soil health.
