摘要
植被通过影响土壤环境，从而影响到土壤微生物群落的结构和多样性．受植被影响的土壤环境中土壤微生物群落的多样性比不受植被影响或者没有植被的土壤环境中的微生物群落的多样性要高很多，不受植被影响的表面以下土壤环境中的微生物群落具有显著的优势ＯＴＵ种群，而表层土壤环境中没有显著的优势ＯＴＵ种群．植被对微生物的影响同时也表现在对生命物质ＤＮＡ的影响，即有植被的土壤环境中的微生物ＤＮＡ具有更高的活性，其基因在克隆过程中更容易被转移，获得更多的克隆细胞和种群．
The overlying vegetation on soil can change surface soil environment, and affect some ecological factors for soil microbial living. The soil environment with plant activity is more suitable for soil microbial population. It’s better for microorganisms to reproduce and grow in the surface soil environment with overlying plants. Diversity is higher in surface soil with overlying plants than that in the soil environment without overlying plants or in the original subsurface soil not affected by vegetation. There is no dominant OTU population in the soil microbial community in the surface soil environment, and there are obvious dominant OTU populations in the subsurface soil environment. Vegetation can affect the activity of DNA from soil microbial community.
