Composition of arbuscular mycorrhizal fungi communities in different proportions in natural mixed forest of Larches and Betula platyphylla in the Cold temperate zone of the Great Khingan Mountains

The Greater Khingan Mountains is a typical ecosystem in the cold region. Through exploring the composition of arbuscular mycorrhizal fungi communities under larches and betula platyphylla in different proportions, the relationship between forest vegetation and soil microbial diversity was revealed.
