Study On The Dominant Tree Biomass And Carbon Storage In Daqing Mountian

This article takes Pinus Tabulaeformis,Betula platyphlla,principis-rupprechtii mayr in daqing mountain as the research object.studying total aboveground biomass in different forest stand in daqing mountain,biomass equations of single plant and closed linear correlation existed between trunk, branches, leaves, bark,other components of biomass and diameter at breast height, tree height, stand volume of living tree volume, stand density ;estimating the carbon storage of typical ecological forest in daqing mountain. the results showed that:Judging from the trunk biomass, principis-rupprechtii mayr > Betula platyphlla > Pinus Tabulaeformis; Judging from the skin biomass , Betula platyphlla > principis-rupprechtii mayr > Pinus Tabulaeformis; Judging from the branches biomass , principis-rupprechtii mayr > Pinus Tabulaeformis > Betula platyphlla; Judging from the leaves biomass , principis-rupprechtii mayr > Pinus Tabulaeformis > Betula platyphlla; Judging from the total aboveground biomass in different forest stand, Betula platyphlla> principis-rupprechtii mayr > Pinus Tabulaeformis.There are very significant linear correlation between the stand biomass of each component of three kinds of forest stand in daqing mountain and the average stand diameter at breast height, average tree height,stand density,the various components of forest biomass and stand volume of living trees linear estimation model of stand biomass and stand volume can be directly applied to the regional scale. From the theory we can propose that linear estimation model of stand biomass can be directly applied to the regional scale.Biomass model and stand volume model are established. W Pinus Tabulaeformis= 8009-248.084V, W principis-rupprechtii mayr = 2686 +453.322 V, W Betula platyphlla = 4349+ 215.95V, and estimating the biomass and carbon storage in different forest stand in daqing mountain. The results show that judging from the carbon storage density, principis-rupprechtii mayr > Betula platyphlla > Pinus Tabulaeformis, in the aspect of carbon storage, Betula platyphlla > Pinus Tabulaeformis > principis-rupprechtii mayr.
