森林的固碳释氧功能对缓解全球气候变暖发挥着重要作用,因此森林碳储量监测日益受到重视,而含碳系数是一项重要的基础计量指标。以东北落叶松为对象,利用假设检验和回归分析方法,对不同器官的含碳系数进行了系统分析,结果表明:落叶松不同器官的含碳系数大都存在显著差异,从大到小依次为:干皮(树枝(树叶(树根(干材;树干上部的含碳系数明显大于中部和下部,但中部和下部的含碳系数没有显著差异;不同大小树根的含碳系数差异不显著,树根与地上部分的含碳系数也没有显著差异;不同器官的含碳系数相对比较稳定,与林木直径和树高等因子无关,但全树尤其是树根生物量的含碳系数与起源相关显著。
The function of carbon sequestration and oxygen release plays an important role in alleviating global warming. Therefore, the monitoring of forest carbon storage has been paid more and more attention, and the carbon content is an important basic measurement index. The results showed that there were significant differences in the carbon content of different organs of Larix gmelinii in the order of descending order: The stems (leaves (stems (dry material; the carbon content in the upper part of the trunk was significantly greater than the middle and lower parts, but the carbon content in the middle and lower parts was not significantly different; There was also no significant difference in carbon content between roots and aboveground parts. Carbon content of different organs was relatively stable, not related to tree diameter and tree height, but the carbon content of whole tree, especially tree root biomass was significantly related to its origin.
