摘  要：
为了研究不同火干扰烈度对喀纳斯泰加林土壤有机碳含量及碳储量的影响,以喀纳斯泰加林同一火烧时间不同火干扰烈度的火烧迹地为研究对象,对不同土层(0～10 cm,10～25 cm)有机碳含量进行测定并估算其碳储量,采用单因素方差分析及LSD多重比较进行差异显著性分析。结果表明,相同火干扰烈度下0～10 cm土层土壤有机碳及碳储量均大于10～25 cm土层。0～10 cm土层中碳储量表现为:未火烧>轻度火干扰>中度火干扰>重度火干扰,在10～25 cm土层中碳储量表现为:轻度火干扰>中度火干扰>未火烧>重度火干扰。0～10 cm土层的土壤有机碳含量和碳储量以及10～25 cm土层的有机碳含量损失程度会随着火干扰烈度的增加而增加。10～25 cm土层碳储量会在轻度和中度火干扰后出现增加。

摘  要：
The aim is to study the effects of fire disturbance on the content of organic carbon and carbon storage of soil in Taiga forest. In this study, soil organic carbon contents in different soil layers(0-10 cm, 10-25 cm) under different fire disturbance intensities in the same fire time of Taiga forest were calculated, and the soil carbon storage was evaluated. The significance of difference was analyzed by the unary variance and LSD multiple. The results showed that the organic carbon and carbon storage in the upper layer(0-10 cm) soil were all greater than those in the lower layer(10-25 cm) soil under the same fire disturbance intensity. The carbon storage in the upper layer(0-10 cm) soil showed: unburned > slight fire > moderate fire > severe fire and that in the lower layer(10-25 cm) soil showed: slight fire > moderate fire > unburned > severe fire. The loss of soil organic carbon content and carbon storage in 0-10 cm soil layer and the organic carbon content in 10-25 cm soil layer increase with the increase of fire disturbance intensity. Carbon storage in the 10-25 cm layer increases after slight and moderate fire disturbance.
