乌拉特荒漠草原群落物种多样性和生物量关系对放牧强度的响应

Abstract

Abstract:

In this paper, the shrub and herb plant communities in the Urat desert steppe in Inner Mongolia were researched. The responses of different grazing treatments (control, moderate grazing and heavy grazing) to the composition of community species, species diversity and relationship between species diversity and aboveground biomass of two plant communities in the desert steppe were studied. The results were as follows: ① With the increase of grazing intensity, the dominant degree of Reaumuria songarica and Allium polyrhizum in shrub grassland community was increased, but that of Stipa glareosa was decreased. Moreover, heavy grazing reduced the dominant degree of S. glareosa and increased that of A. mongolicum and A. polyrhizum in the herb grassland community; ② Different grazing treatments reduced significantly the coverage and height of both two grassland communities and the density of shrub grassland community (P<0.05), and removed the difference of coverage between the shrubs and herbs in the grassland community (P>0.05). Moderate grazing reduced the Pielou evenness index in shrub grassland community, and heavy grazing reduced the species richness in shrub grassland community. There were no significant differences in other diversity indices in both shrub and herb grassland communities under the grazing treatments (P>0.05). Except for species richness, the difference of other diversity indices between shrub and herb grassland communities were significant (P<0.05); ③ Different grazing treatments reduced significantly the aboveground biomass and litter biomass in shrub and herb grassland communities, and resulted in the significant difference of aboveground biomass between shrub and herb grassland communities (P<0.05); ④ There was a negative correlation between aboveground biomass and Simpson dominance index, and also a positive correlation between aboveground biomass and Shannon-Wienner diversity index and also between aboveground biomass and Pielou evenness index. Furthermore, aboveground biomass was positively correlated with density and species richness under grazing treatments. Additionally, grazing treatments changed the composition, structure and function of plant community in desert steppe, and then changed the important relationship between community structure and function.

Key words: desert steppe, grazing intensity, community structure, species diversity, aboveground biomass, Inner Mongolia
