Bryophyte biomass in dark coniferous forest of Changbai Mountain

Abstract

Abstract: In this paper,the floor and epiphytic bryophyte biomass was sampled from the dark coniferous forest on the north slope of Changbai Mountain,with an altitude from 1100 m to 1700 m.The floor bryophyte biomass was measured by the method of transect sampling,and epiphytic bryophyte biomass was measured by McCune method.The results showed that bryophytes distributed unevenly,and their biomass changed greatly with increasing altitude.The biomass was the least (543 kg穐m^-2) at 1 100 m,but the greatest (5 097 kg穐m^-2) at 1 250 m.The changes of bryophytes biomass could indicate different environmental situations.The biomass change of Hylocomium splendens and Rhytidiadelphus triquetrus with ascending altitude had some relativity with the community character of forest ecosystem.The biomass of Hylocomium splendens increased,but that of Rhytidiadelphus triquetrus decreased with altitude ascending from 1 100 m to 1 700 m.Moreover,the biomass changes could also show the needed physiological conditions of different bryophytes.

Key words: Dark coniferous forest, Bryophyte, Biomass, Hylocomium splendens, Rhytidiadelphus triquetrus, Changbai Mountain
