| 摘 要： | 土壤微生物是草地生态系统的重要组成部分,在养分循环、有机质降解和植物多样性维持等方面发挥着重要作用.利用土壤微生物对环境变化的敏感性,以其特性变化来表征草地生态系统当前的状况,能较早的对退化系统做出预警.文章综述了天然草地土壤微生物特性,以及在放牧、刈割、围封、氮肥添加4种不同人为干扰下土壤微生物特性变化的研究进展,并对未来研究进行了展望. |
| 关 键 词： | 草地生态系统 土壤微生物 微生物量 微生物群落结构 人为干扰 |

| Abstract: | Soil microorganism is an important part of grassland ecosystem and plays a significant role in the degradation of organic matter, nutrient cycling and plant diversity maintenance, etc. Taking advantage of the environmental sensitivity of soil microorganism, the degenerate system of grassland is able to be predicted early. The characteristics of soil microorganisms in natural grassland, and the advances of property changes of soil microorganism under different human disturbances including grazing, mowing, enclosure and nitrogen fertilizer addition treatments are reviewed in this paper. The prospects of research directions are forecast at the same time. |
| Keywords: | Grassland ecosystem Soil microorganism Microbial biomass Microbial community structure Human disturbance |
