Title: Investigation on Biomass of Different Vegetational Type of Grassland in Alpine Meadow of Gemutan
Abstract: The biomass of different vegetational type of grassland in Alpine meadow of Gemuton was investigated.The results showed that there was the significat difference in the biomass of different vegetationcl type of grassland(P0.05),and the above-ground biomass and the under-ground biomass of different vegetational type of grassland showed the order as follows:Kobresia tibetica swamp meadowSalix oritrepha shrub meadowK.pygmaca meadow.Changes of Biomass of above-ground in different functional group composition,biomass of above-ground of sedges showed the pattern like this:K.tibetica swamp meadowSalix oritrepha shrub meadowK.pygmaca meadow,biomass of above-ground of gramineae and forbs both showed the pattern like this:Salix oritrepha shrub meadowK.tibetica swamp meadowK.pygmaca meadow,In the various plots,biomass of under-ground were decreasing with increasing of soil depth.
