Effect of grazing intensity on the phytosociological character of the Hulunbuir steppe

doi:10.11686/cyxb20150121

Abstract

Abstract: Phytosociology is the study of the composition, distribution and relationships between different species in plant communities. This study used the Braun-Blanduet and functional grouping methods to clarify the rules governing community structure and species characteristics in the Hulunbuir (Stipa krylovii) steppe under different grazing intensities. Two main associations and two sub-associations were found. Following increased grazing intensity, those species with good resistance to grazing and drought, for example, Allium species were frequently present while the frequency of palatable species reduced, some disappearing. There were significant differences in community structure, species number and diversity index due to different grazing intensities.
