冀北山地森林碳储量探究——以雾灵山保护区为例

Research on Forest Carbon Storage in Mountainous Areas of Northern Hebei Province——Taking Wuling Mountain Conservation Area as an Example

为定量分析河北雾灵山国家级自然保护区的森林碳储量,了解森林碳储量与森林生产发展变化的趋势,以雾灵山保护区2020年森林资源连续清查数据为基础,在相关研究的基础上,采用前人建立的生物量及碳储量估算模型和回归方程,对保护区内森林的树种结构、年龄结构、生物量、碳储量、碳密度指标进行了调查与分析。结果表明:雾灵山自然保护区森林总碳储量为311695.41 t,其他软阔类在面积、生物量和碳储量等方面都占有相对优势,但白桦和其他硬阔类在碳密度方面表现突出。

The purpose of this paper is to quantitatively analyze the forest carbon stock of the Wuling Mountain National Nature Reserve in Hebei Province and understand the trend of forest carbon stock and forest production development and changes.Based on the continuous inventory data of forest resources in the Wuling Mountain Nature Reserve in 2020,and on the basis of relevant research,the biomass and carbon stock estimation model and regression equation established by predecessors are used.The tree species structures,age structures,biomass,carbon stock and the carbon density index are investigated and analyzed.The results show that the total carbon storage of forest in Wuling Mountain Nature Reserve is 311695.41 t,and other soft broadleaved species have comparative advantages in terms of area,biomass and carbon storage,but birch and other hard broadleaved species have outstanding performance in terms of carbon density.
