摘要: 以五常凤凰山林场皆伐迹地上45年生不同起源(人工造林、人天混更新、天然更新)形成的落叶松纯林、落叶松与阔叶树混交林和次生阔叶林3种林分为研究对象,调查分析不同林型林分乔木层、灌草层、凋落物层、土壤层碳储量以及3种林型林分总碳储量,分析不同更新方式对森林碳储量的影响,探究具有高固碳能力的森林更新方式。研究结果表明:人天混交林能增加林分灌草层碳储量(P<0.05);凋落物未分解层碳储量、半分解层碳储量和凋落物总碳储量均以落叶松纯林最高,且半分解层碳储量和凋落物总碳储量在3个林型间差异显著(P<0.05);土壤总碳储量以及森林生态系统总碳储量针阔混交林均略高于其它两种林分,但差异并不显著(P>0.05)。研究表明人天混更新有利于植被碳汇和土壤碳汇能力的提高。人工针叶纯林具有较高的凋落物碳储量。

Abstract: In Wuchang Fenghuangshan Forest Farm on the west slope of Zhangguangcai Mountain, we selected Larch(Larix olgensis L.), Larch and broad-leaved mixed forest(H), and secondary broad-leaved natural forest(C) in different origins(artificial regeneration, artificial-natural regeneration, and natural regeneration) to study the carbon storage of tree layer, shrub and grass layer, the litter layer, soil layer and the total carbon storage of all three types of forest stands, explore the effects of different ways of regeneration on forest carbon storage, and determine the way of forest regeneration with high carbon sequestration capacity. Artificial-natural mixed stand could increase the carbon storage of the shrub and grass layer(P<0.05). L showed the highest carbon storage of undecomposed litter layer, semi-decomposed litter layer and the highest total carbon storage of litter, and its carbon storage in the semi-decomposed litter layer and the total carbon storage of litter were significantly different in the three forest types(P<0.05). The total soil carbon storage and the total carbon storage of the forest ecological system were higher in H than that in the other two forest types, but the difference was not significant(P>0.05). The artificial-natural regeneration was conductive to increasing the carbon sink capacity of vegetation and soil, and Larch artificial regeneration had high carbon storage of litter.
