土壤真菌多样性及分子生态学研究进展

摘要/Abstract

摘要： 真菌是土壤中一类重要的微生物,参与有机质分解,与植物共生为植物提供养分,同时病原真菌也会引起粮食产量的降低.土壤真菌多样性在维持生态系统的平衡和为人类提供大量未开发资源上起到了独特而重要的作用.本文从物种多样性、生境多样性、功能多样性角度阐述了土壤真菌多样性,并从农田、林地、草地、极端环境与一些复杂环境土壤真菌多样性层面综述了土壤真菌多样性分子生态学研究进展,同时论述了一些影响真菌多样性的因素,并对土壤真菌多样性研究的前景提出展望.

Abstract: Fungi are a kind of important soil microorganisms that participate in the decomposition of organic materials and supply nutrients to the plant through symbiosis.But,they can also reduce the output of food due to the existence of pathogenic fungi.Soil fungal diversity plays a fundamentally unique role in maintaining the balance of ecosystem and in supplying large amount of undeveloped resources for the people.In this paper,soil fungal diversity was expatiated from the viewpoints of species diversity,habitant diversity and functional diversity,and furthermore,the research advances in the molecular ecology of soil fungal diversity were reviewed from the aspects of the fungal diversity of farmland,woodland,pasture,extreme environment,and other complex environments.The affecting factors of soil fungal diversity were discussed,and the development trend of the study on soil fungal diversity was also approached.
