Abstract

Abstract:

Potaninia mongolica is an important constructive species and paleoendemic species in the Alxa desert, and it is a national secondary key protected plant species in China. Investigating the characteristics of the natural communities of Potaninia mongolia and its community classification can provide data support for the conservation and long-term monitoring of this species. In this study, 14 plots were investigated in eastern Alxa, and the quantitative characteristics of communities were studied by quadrat method. The results showed that: (1) A total of 48 plants species were recorded in the investigated communities, belonging to 39 genera of 14 families, dominated by Gramineae, Amaranthaceae, Compositae and Leguminosae. Annual or biennial herbaceous species were the dominant life form, accounting for 33.33% of the total species. Perennial herbs (25.00%), shrubs (20.83%) and semi-shrubs (20.83%) had similar proportions, but shrubs constituted the dominant layer of the community. Xerophytes are the primary water ecological type, accounting for 79.17% of the total species, of which strong xerophytes accounted for 35.42%, reflecting the climatic characteristics of intense aridity. Gobi species and gobi-Mongolia species dominate the floristic geographic elements, accounting for 29.16% and 22.92%, respectively, reflecting the floristic characteristics of desert vegetation. (2) According to the coexisting life forms and the degree of dominance, Potaninia mongolica desert in eastern Alxa was classified into four Association Groups: Potaninia mongolica - Herb Desert Association Group, Potaninia mongolica + Shrub - Herb Desert Association Group, Potaninia mongolica + Shrub Desert Association Group, Potaninia mongolica - Semi-shrub - Herb Desert Association Group, which were further divided into 13 Associations.

Key words: eastern Alxa, Potaninia mongolica, community characteristics, community classification
