Research progress on effect of grazing on soil microbes of grassland

This paper summarized the research of different grazing intensities on compose of soil microbes, number of microbes and change of microbes in timespace of grassland in China, and the effect of different utilization ways on microbes. Soil microbes of grassland were composed of fungi, bacteria and actinomycete, which were the most three populations. The number of soil bacteria was the highest, the second was actinomycete, and the number of fungi was the lowest. In spatial, the numbers of soil microbes were all gradually decreasing with increase of soil depth. Season change of soil microbes increased with the increase of soil temperature in spring, and the highest on mid of August and the lowest in winter. So, soil microbes were very important for energy flow and matter translation in grassland ecosystem.
