Aboveground Biomass and Importance Value of Constructive Species in Desert Steppe Are Co-Regulated by Grazing Intensity and Climate.

ABSTRACT: Constructive species are the creators and constructors of plant communities, exerting significant control over community structure and environmental formation. This study investigates the effects of grazing intensity on the biomass and importance value of the constructive species in a desert steppe and its contribution to community biomass. This study conducted a 5-year monitoring on a long-term grazing experimental platform in desert grasslands. The experiment set four grazing intensities, and from May to September each year, the aboveground biomass, plant height, density, and community biomass of the community were measured. Results showed that different grazing intensities altered the importance value and aboveground biomass of Stipa breviflora, which were regulated by rainfall a
