Abstract: In order to reveal the distribution characteristics of community biomass along the horizontal environmental gradients or among the vertical layers of communities in Ergis river,this paper studied the biomass distribution characteristics of 6 forest stands,several analysis methords are used such as study plot,trunk analysis and experience model.The results showed that variation range of average organs biomass are in order trunk 59.485~100.697 t·hm-2,bark 7.649~19.434 t·hm-2,branch 6.366~40.208t·hm-2,leaf 1.834~5.694 t·hm-2,root 11.820~46.265 t·hm-2. All existent significant power correlation between each organs biomass of P.laurifolia, P.jrtyschensis, P.alba,S.alba and DBH,correlated equation is M=aDb(R2=0.884~0.984). Vertical distribution of community biomass in order tree layer>shrub layer>herb layer>litter layer showed inverted pyramid shape. Community biomass presented a unimodal form of increasing before decreasing with the distance increasing from the river channel.
