Species Diversity of Plant Community in Shigaoshan
The species richness index,diversity indices and evenness indices were used to study the species diversity of different plant communities and the relationships with elevation gradient,aimed to reveal the species diversity of community and the structure on elevation gradient in Shigaoshan,Shanxi.The results indicated that:1) On the community vertical structure,the species richness index order was as follows:herb layer＞shrub layer＞tree layer;2) The richness index size of the order which contrast to the diversity index and evenness index in different communities was deciduous broad-leaf forest ＞ coniferous and broad-leaf forest ＞ coniferous forest ＞ shrub ＞ herb-shrub;3) With altitude increase,species richness increased first and then decreased,diversity and evenness drop before they rise and the fitted curves of richness index,diversity index and evenness index with altitudinal gradient were more significant.
