Above-ground Carbon Storage Allocations of Main Tree Species in Broad-leaved Natural Secondary Forest of Changbai Mountains

Abstract

Abstract: Based on the investigation data of 8 sampleplots of Jingouling station of Changbai mountains in 2007,the paper analyzed above-ground standing carbon storage of main tree species(DBH ≥4cm)and their distribution according to DBH(diameter at breast height) classes and layer height classes. The results are showed as following: (1) The amount of above-ground standing carbon storage of main tree species is in this sequence: Betula spp(20 675.902kg/hm²)>Acer mono Maxim.(7 065.584kg/hm²)>Tilia amurensis Rupr.(4 740.284kg/hm²)>Populus davidiana (3 777.076 kg/ hm²)>Fraxinus mandshurica Rupr.(3 440.810kg/hm²)>Picea asperata Mast. and Abies nephro- lepis (2 430.327kg/hm²)>Pinus koraiensis Sieb.(1 625.146kg/ hm²). (2) The carbon-storage curve of Pinus koraiensis Sieb.,Picea asperata Mast. and Abies nephrolepis were stabler than broadleaved tree species 's. (3) Carbon storage' distribution according to layer height class increased remarkably with height increasing,after that carbon storage decreased with height increasing in the tree level. Stem' carbon-storage percentage of above-ground carbon storage in broad leaved tree species deceased as the tree height classes increased,but Pinus koraiensis Sieb,,Picea asperata Mast. and Abies nephrolepis were on the contrary.

Key words: biomass, carbon storage, allocations in each layer height class, allocations in each DBH class
