Amygdalus mongolica is a kind of rare and endangered plant in China, which has high academic value and diagnostic significance for the evolution of the flora and the biodiversity and stability of the ecosystem. The 14 Amygdalus mongolica sites were set up to investigate its community composition in Ningxia. The results showed that the 74 plant species in Amygdalus mongolica sites in Ningxia belong to 53 genera from 28 families were recorded, including 2 trees, 21 shrubs, 11 subshrubs, 36 perennial herbs and 4 annual herbs. TWINSPAN divides 14 Amygdalus mongolica sites into Amygdalus mongolica - Herbs Desert, Amygdalus mongolica - Subshrubs Desert Associations Group and Amygdalus mongolica - Stipa tianschanica var. gobica, Amygdalus mongolica - Oxytropis aciphylla, Amygdalus mongolica - Stipa breviflora, Amygdalus mongolica - Ajania achilleoides, Amygdalus mongolica - Elymus alashanicus, Amygdalus mongolica - Ajania achilleoides + Stipa breviflora 6 Associations. Our study will provide basic data for the protection, utilization and compilation of vegetation of Amygdalus mongolica.
