研究了东北东部张广才岭西坡东北林业大学老山人工林实验站于1966年春栽植的红松人工林生态系统(包括:红松(Pinus koraiensis)人工纯林,红松蒙古柞(Quercus mongolica)混交林,红松白桦(Betula platyphylla)混交林土壤有机碳质量分数、碳密度和储碳能力,研究结果表明,土壤碳库是由土壤L层、F层、H层和B层分室构成,每个分室具有储碳功能和潜力。经双因素方差分析得知,不同红松人工林生态系统类型、不同土层分室、不同坡位种类均对Soc质量分数,Soc密度有显著影响,红松蒙古柞混交林Soc密度最高为278.63 Mg·hm-2,以分室比较属B层分室碳密度最高,为212.28 Mg·hm-2,以坡位比较坡下Soc密度最高,为394.1 8 Mg·hm-2,同时揭示了Soc质量分数,Soc密度与各分室有机质含量,分室的土壤垂直深度有明显的规律。这些研究结果说明,温带湿润地区地带性红松人工林与天然林混交的生态系统土壤有较高的碳储能力,为防止气候转暖,实施减排发展低碳经济提供参考。图3表8参12。
This paper studied the Pinus koraiensis plantation pure Pinus koraiensis plantation and the mixed Quercus mongolica plantation in the spring of 1966 in Laoshan plantation experiment station of Northeast forestry university in the northeast of Northeast China. The results showed that the soil carbon pool consisted of the soil L, F, H and B compartments, each of which had a soil organic carbon mass fraction, carbon density and carbon storage capacity in the Betula platyphylla mixed forest. According to two-factor analysis of variance (ANOVA), it was found that different types of Pinus koreanum plantation ecosystems, different soil compartments and different slope types all had significant effects on Soc mass fraction and Soc density. The highest density of Soc in the mixed forest was 278.63 Mg · hm-2, the highest density was 212.28 Mg · hm-2 in the sub-compartment of the B-compartment, and the highest SOC density was 394.1 8 Mg · hm-2 , Revealing the Soc mass fraction, Soc density and the organic matter content in each compartment, and the vertical depth of soil in the compartment have obvious rules.These results indicate that the ecosystem soil mixed with natural forest and Pinus koraiensis plantation in the temperate zone has Higher carbon storage capacity, in order to prevent climate warming, the implementation of emission reduction for the development of low-carbon economy to provide a reference.
