Abstract:: Shrub-grass vegetation plays an important role in maintaining the functions of ecosystems. On degraded lands, different disturbances might alter species diversity and distribution pattern of shrub-grass vegetation, and even the relationship between plant species diversity and productivity. However, our knowledge of the consequences of these effects on diversity and composition of ground flora remains very poor. In this study, we examined the species diversity, productivity and the relationship between diversity and productivity in undisturbed, grazing and fire vegetation of northwest Guangxi. It’s found that shrubs exhibited lower species richness and Shannon-Wiener index under both grazing and fire treatments than those of the undisturbed site. Moreover, compared with undisturbed treatment, the evenness index of shrubs differed insignificantly under grazing treatment, while it’s reduced by fire treatment. With respect to grass species, grazing had no influence on their diversity, but it did reduce the Shannon-Wiener index and evenness index distinctly. On the contrary, fire treatment decreased the grass species diversity, whereas it showed little effect on the Shannon-Wiener index and evenness index. In addition, the relationship between species diversity and productivity of shrubs and grasses was also affected inconsistently by grazing and fire treatment.
