摘要
土壤微生物是森林生态系统中十分重要的一个组分部分,大量研究表明,生态系统的功能、结构以及土壤肥力会受到土壤微生物的直接影响。本文通过对土壤微生物多样性相关文献的查阅、整理、归纳,总结了其研究进展,目前,关于土壤微生物多样性的研究主要集中在物种、遗传、结构、功能等四个方面。还从微观角度分析了其影响因素,自然因素主要涉及水分,土壤pH值、土壤温度以及植被等方面,人为因素主要涉及种植制度和施肥两个方面。
Soil microorganisms are a very important component of forest ecosystem.A large number of studies have shown that the function,structure and soil fertility of ecosystem are directly affected by soil microorganisms.In this paper,the research progress of soil microbial diversity was summarized by reviewing,sorting and summarizing relevant literature.At present,the research on soil microbial diversity mainly focuses on species,heredity,structure and function.The influence factors are also analyzed from the micro point of view.The natural factors mainly involve water,soil pH value,soil temperature and vegetation,and the human factors mainly involve planting system and fertilization.
