[Colonization and community structural features of AM fungi in urban ecosystem: a review].

Arbuscular mycorrhizal (AM) fungi, an important component of soil microbes, are of significance in maintaining the sustainable development of urban ecosystem. This paper summarized the characteristics of the colonization and community structure of AM fungi in urban ecosystems, and discussed the effects of urban ecological factors, e.g., human activities, vegetation re-establishment and maintenance, and urban soil status, on the colonization and community structure. It was considered that the researches on the community structure and function of AM fungi in urban ecosystems, such as the effects and mechanisms of the key urban ecological factors (e.g., water resource shortage and heat island effect) on the alternation of AM fungal community structure should be strengthened in the future.
