Abstract
According to group test planning,28 plots of plant communities were established along the road slope of Hushaan Highway between Xinyang and Nanyang.Species diversity indices of the plants growing the slopes with different soil types were compared.Relationship between vegetation factors and species diversity was studied.The results showed that the correlations among the Shannon Weiner index,Margalef index and Pielou index of two communities were relatively higher: Amorpha fruticosa+ Cynodon dactylon+Festuca elata community,and Lespedeza bicolor+C.dactylon+Festuca elata community.A significant relationship was observed among species diversity indexes.The Shannon Weiner index,margalef index and pielou index were related remarkly with aboveground biomass,while there was a poor correlation between species diversity indices and the vegetation height,the vegetation coverage and the coefficient of soil conservation.The coefficient of soil conservation was closely related to the vegetation coverage,and remarkable correlated to the vegetation height.
