The Study Of Single Biomass, Carbon Storage And Distribution Of Larix Principis-ruppr Echtii And Populus In Hebei Province

As the main body of the terrestrial ecosystem, the forest has a wide distribution area, the highest level of biological productivity and the largest biomass accumulation. Forests absorb CO2 and have the ability to long-term preservation of CO2. They play a tremendous role of the "biological pump" in the exchange of carbon between the terrestrial ecosystems and atmospheric carbon pools. Therefore, establishing the single plant biomass model and carbon storage model, building up a unifying standard, which have far-reaching significance.In this paper, as the research of single biomass and carbon storage of Larix principis-rupprechtii Mayr. and Populus in Hebei province, we have found out the allotment regulation, and build up the model of DBH, height, volume, biomass and carbon storage, and analyzed they. The results are as follows.1 The allotment regulation of biomass and carbon storageIn Hebei province, with the increase of DBH, the allotment regulation of biomass and carbon storage of Larix principis-rupprechtii Mayr. and Populus is as follows: the proportions of trunk biomass and carbon storage are the largest; the proportion of roots biomass and carbon storage are basically stable, which have remained at about 20%; the proportion of leaf biomass and carbon storage is decreasing. The proportion of branches and leaves biomass and carbon storage of Populus have more fluctuations than Larix principis-rupprechtii Mayr.2 The regression model of DBH, tree height and biomassApplied the software SPSS17.0, we carry on Pearson relativity analysis to DBH, height, biomass and carbon storage of Larix principis-rupprechtii Mayr. and Populus. The results are as follows. DBH, biomass and carbon storage of the two species have a highly significant correlation (P<0.01,NL=63,NP=20). Height, biomass and carbon storage of Larix principis-rupprechtii Mayr. have a highly significant correlation (P<0.01,NL=63,NP=20). Height, biomass and carbon storage of Populus. have lower significant correlation. The models of W = a(D 2H)b and W = aDb can nicely draw up to match the relationship betweens DBH, height and biomass, carbon storage. But the model of W = a(D~ 2H)~b is much better.3 the relationship of volume, biomass and carbon storageApplied W = a+bV model to the volume, biomass with carbon storage, we find that it is good to draw up to match effect between take skin volume measure or to the skin volume measure and biomass or carbon storage of the two trees. Applied C = aV~b model to the volume with carbon storage to carry on drawing up to match, its correlation coefficient is higher than the W = a+bV model’s. It is mean that the C = aV~b model can get better draw up to match effect, we should consider it first.
