On Carbon Sequestration Rates and Differences of Main Tree Species in Changbai Mountain Forest Area
摘要
Abstract
In order to estimate the carbon storage of regional forest accurately,the organic carbon sequestration rate of different organs of 14 main tree species in Changbai Mountain forest area was determined by wet-burning method.Meanwhile,the single-tree biomass equation of each tree species was used to determine the average carbon content.The results show that average carbon contents of the whole plant of the 14 species were 44.56%, 48.77%,49.44%,38.59%,49.76%,45.08%,45.53%,45.37%,45.38%,48.40%,52.20%,50.26%, 50.79%,53. 39% in Acer mono,Populus davidiana,Tilia amurensis,Ulmus japonica,Betula costata,Betula platyphylla,Maackia amurensis,Fraxinus mandshurica,Juglan mandshurica,Quercu mongolica,Abies nephrolepis, Pinus sylvestris,Larix gmelinii and Pinus koraiensis,and indicate that the carbon content in coniferous species is more than that in broad leaf species.The difference between the weighted average carbon content of whole plant species and the average carbon content of their organs is within 1.39%. The variation of carbon content in different organs of each species ranged from 33.98% to 53.98%,and the overall performance was stem>branch>root>leaf.The coefficient of variation of different organs within the species ranged from 1.10% to 7.98%,and the coefficient of variation of carbon content in organs ranged from 7. 60% to 11. 29%. Further multiple comparisons showed that the carbon content of different organs of the same species differed significantly in significance level and had no certain regularity.There was a certain similarity between some species of organs at the carbon content of organs.关键词
