【摘要】：利用山东省第7次森林资源清查数据,采用生物量-蓄积量转换函数和平均生物量法,结合不同树种的含碳率,研究山东省森林生态系统立木碳储量、碳密度及其按优势树种、龄组和林种的分布特征.结果表明:2007年山东省森林立木碳储量为25.27 Tg,其中,针叶林、针阔混交林和阔叶林的立木碳储量分别占全省立木碳储量的8.6%、2.0%和89.4%.不同林龄组的立木碳储量大小顺序为幼龄林中龄林成熟林近熟林过熟林,其中幼龄林和中龄林占全省立木总碳储量的69.3%.用材林、经济林和防护林的立木碳储量分别占全省立木碳储量的37.1%、36.3%和24.8%.山东省森林平均立木碳密度为10.59 t·hm-2,低于全国平均水平,主要是由于现有森林用材林和经济林比重高,中幼林多、成过熟林少.
[Abstract]:Based on the data of the 7th forest resource inventory in Shandong Province, the carbon storage, carbon density and dominant tree species in forest ecosystem of Shandong Province were studied by using the biomass-volume conversion function and the average biomass method, combined with the carbon content of different tree species. Distribution characteristics of age groups and forest species. The results showed that the carbon storage of standing trees in Shandong Province was 25.27 Tg in 2007. Among them, the standing carbon reserves of coniferous forests, coniferous broadleaved mixed forests and broadleaved forests accounted for 8.6% and 89.4% of the total standing carbon reserves in Shandong Province, respectively. The order of standing carbon storage in different forest age groups was that the mature forest was near mature and the young and middle aged forest accounted for 69.3% of the total carbon storage of stumped trees in the whole province. The standing carbon storage of timber forest, economic forest and shelterbelt forest accounted for 37.1% and 24.880% of the total standing carbon storage in the province, respectively. The average stand carbon density of forest in Shandong Province was 10.59 t 路h ~ (-2), which was lower than the national average level, mainly due to the high proportion of existing forest timber forest and economic forest, the large number of middle and young forest, and the less overmature forest.
