摘　　要：综述宁夏多种生态环境中AM真菌种群落多样性。通过对多种土壤因子、土壤类型、植被类型与AM真菌多样性、孢子密度以及菌根侵染率的关系比较,探讨环境因子对AM真菌多样性的影响。研究表明,宁夏不同土壤类型区域中AM真菌种类及分布在一定程度上是与植被类型、植物多样性和土壤肥力特征相对应的。Abs The paper reviewed the AM fungi diversity in diverse ecological habitats in Ningxia, and then discussed the impact of environmen- tal factors on AM fungi diversity from the relations of multiple environmental factors of soil types and vegetation types with the diversity, spore density and infection rate of AM fungi. The species and distribution of AM fungi are related to vegetation types, plant diversity and soil fertiliz- er characteristics in Ningxia to a certain degree.
