摘　　要：利用黑龙江省穆棱市下属的3个林场2012年、2016年两期森林资源固定样地调查数据,研究森林固碳情况以及树种、平均胸径、平均树高、每公顷株数、海拔和坡度等因素对森林碳储量的影响情况。结合生物量相容性模型以及不同树种含碳系数估算各林场内样地碳储量情况,使用ArcGIS的普通克里金插值方法,空间插值得到并分析两期碳储量空间分布格局及其动态变化。分析碳储量与海拔、坡度等地形因子和树高、胸径等林分因子之间的关系,并得到碳储量估算模型。结果表明:研究区域碳储量总量呈上升趋势,森林碳汇功能不断增强,中西部碳储量明显高于其他地区,东南部碳储量相对较低,阔叶混交林、柞树和人工落叶松在该区域森林植被碳汇功能中扮演重要角色。结果表明:森林固碳情况良好,应更加注重森林资源的保护及分布平衡等问题。In order to study the carbon sequestration of forests and its influencing factors such as tree species,mean DBH,average tree height,stems per hectare,altitude,slope and so on,this paper used two types of the forest resources permanent sample plot survey data from three typical forest farms in Muling City,Heilongjiang Province in 2012 and 2016.The carbon storage capacity of each forest farm was estimated by combining the biomass compatibility model and the carbon content of different tree species.Using ArcGIS’s ordinary Kriging interpolation method,spatial interpolation was used to obtain and analyze the spatial distribution pattern and dynamic changes of the two phases of carbon storage.The relationship between carbon storage and topographic factors such as elevation and slope,and forest stand factors such as tree height and DBH were analyzed,and a carbon storage estimation model was obtained.The results showed that the total carbon storage in the study area was on the rise,the forest carbon sink function was strengthening,the carbon storage in the central and western regions was significantly higher than those in other regions,and the carbon storage in the southeast was relatively low,the broad-leaved mingled forest,oak trees and artificial larch all played an important role in the carbon sink function of forest vegetation in this region.Conclusion:forest carbon sequestration was in good condition,and more attention should be paid to the protection and distribution balance of forest resources.
