doi:10.17521/cjpe.2021.0055

Abstract

Abstract:

Ephedra rhytidosperma is an endemic and endangered plant in East Alxa, and its community is one of the unique desert plant communities in the Helan Mountain. In this paper, we investigated 16 plots of the E. rhytidosperma community in 2019 and analyzed its flora characteristics, applied TWINSPAN to classify community types. Results showed that: 1) The species composition of E. rhytidosperma community was dominated by Gramineae, Compositae, Leguminosae and Zygophyllaceae, belonging to 13 families, 24 genera and 27 species. 2) The main life forms of E. rhytidosperma community were perennial herbs (44.44%) and shrubs (29.63%); the main floristic geographic elements were Palaeo-Mediterranean element (44.44%) and East Asia element (33.33%); the main ecological types of water were xerophyes (40.74%) and super-xerophytes (37.04%). 3) Based on the life forms and species composition, the E. rhytidosperma communities were divided into two major Association Groups. Ephedra rhytidosperma - Semi-Shrub Desert and Ephedra rhytidosperma - Herb Desert, which were further divided into 3 Associations: Ephedra rhytidosperma - Convolvulus tragacanthoides - Lespedeza davurica Semi-Shrub and Herb Desert, Ephedra rhytidosperma - Convolvulus tragacanthoides - Ptilagrostis pelliotii Semi-Shrub and Herb Desert and Ephedra rhytidosperma - Ptilagrostis pelliotii Semi-Shrub and Herb Desert.

Key words: Ephedra rhytidosperma, life form, flora composition, community classification
