Carbon Coefficient Regularity Of Spruce And Pine

The forest has been playing a vital role in altering global climate. Therefore, it is essential to reinforce monitoring of forest carbon storage and study carbon fixation and oxygen release of the forest. To be emphasized, carbon content factor (CCF) is a key index. Based on the data of dragon spruce (picea asperata) and masson pine (pinusmassoniana), the CCF’s of different organs of the same tree species and the same organ of different tree species have been analyzed systematically using Hypothesis test and regression analysis. The result has indicated that:(ⅰ) the CCF’s of different organs in dragon spruce (picea asperata) are significantly different, and the order by CCF from the lowest to the highest is stemwood, root, stembark, branch and foliage;Dry wood, roots, bark, branches, leaves carbon coefficients are as follows:0.5321、0.5382、0.5440、0.5699.(ⅱ) the CCF’s of different organs in massonpine (pinusmassoniana) are significantly different, and the order by CCF from the lowest to the highest is stembark, branch, root, stemwood and foliage;Dry skin, branches, roots, dry wood, leaves carbon coefficients are as follows:0.4507、0.4883、0.4951、0.5010、0.6064.(ⅲ) the CCF’s of stemwood and stembark on different heights are significantly different, whereas theCCF’s of branches in different storeys and CCF’s of roots in different size classes are not significantly different;(iv) the CCF’s of different organs are relatively stable, and are not related significantly to the tree origin,diameter and height.
