Abstract
Three richness indices, four species diversity indices and five evenness indices were used to analyze vegetation in Luya Mountains, Shanxi. In addition, relationships among these indices were studied by correlation analysis. The results indicated that: 1) the evenness indices increased with the increase of elevation, while the richness indices and species diversity indices showed the opposite trend; 2) the species diversity indices order of the vegetation type was as follows: deciduous broad_leaf forestconiferous and broad_leaf forestwarm coniferous forestcool temperate coniferous forestdeciduous broad_leaf shrubsubalpine shrub and grasslandherb_shrub; 3) the relationship among the 12 diversity indices were well reflected by the two_dimensional ordination diagram of DCA; 4) there were very significant correlation among richness indices, among species diversity indices and among evenness indices. All richness indices, species diversity indices and evenness indices were compared with each other, in which R 0、N 1、N 2、E 4 and E 5 were superior to the others.
