Abstract:ased on data from 125 Plots,species richness, evenness and species diversity of plantcommunities in Dongling Mountain were discussed. Generally speaking plant communities inthe area from 1300m to 1600m above sea level high diversity and in turn are those in the areafrom 1600m to 2303m and then below 1300m.The species richness and diversity indices de-crease along with the increase of elevation,while the evenness is on the contrary. The speciesrichness of tree stratum and shrub stratum are similar which are ...
