摘要
【目的】通过对青岛市森林生态系统碳储量进行研究,掌握青岛市森林生态系统碳储量及碳密度分布,为青岛市林业行业和相关管理部门的决策提供科学依据。【方法】基于165块典型样地调查数据并结合2021年林草生态综合监测评价数据,估算青岛市森林生态系统的碳储量和碳密度。【结果】(1)青岛市森林生态系统总碳储量为1831.58万t,其中地上生物量、地下生物量、枯落物、粗木质残体、土壤碳储量分别为460.35×10^(4) t、89.09×10^(4) t、28.30×10^(4) t、2.01×10^(4) t、1251.83×10^(4) t,分别占总碳储量的25.13%、4.86%、1.55%、0.11%、68.35%;(2)青岛市森林生态系统的碳密度为115.16 t·hm^(-2),碳密度的大小顺序为土壤(78.73 t·hm^(-2))>地上生物量(28.92 t·hm^(-2))>地下生物量(5.60 t·hm^(-2))>枯落物(1.78 t·hm^(-2))>粗木质残体(0.13 t·hm^(-2));(3)青岛市森林生态系统碳密度较高的区域主要分布在北部、东南部和南部三大山区,碳密度较低的区域则主要集中在中部平原地区。【结论】青岛市森林生态系统碳密度略高于山东省平均值,但与林业发达地区还存在一定差距,未来可通过加强幼、中龄林经营管理进一步提升青岛市森林生态系统固碳能力。
【Objective】To study the carbon storage and carbon density distribution of the forest ecosystem in Qingdao city,and provide scientific basis for decision-making by the forestry industry and relevant management departments.【Method】Based on the survey data of 165 typical sample plots and combined with the comprehensive monitoring and evaluation data of forest and grass ecology in 2021,the carbon storage and carbon density of the forest ecosystem in Qingdao city were estimated.【Result】(1)The total carbon storage of the forest ecosystem in Qingdao city is 18.3158 million tons,of which the aboveground biomass,underground biomass,litter,coarse wood residue,and soil carbon storage are 460.35×10^(4) t,89.09×10^(4) t,28.30×10^(4) t,2.01×10^(4) t,1251.83×10^(4) t,respectively,accounting for 25.13%,4.86%,1.55%,0.11%,and 68.35%of the total carbon storage.(2)The carbon density of the forest ecosystem in Qingdao is 115.16 t·hm^(-2),with the order of soil(78.73 t·hm^(-2))>aboveground biomass(28.92 t·hm^(-2))>underground biomass(5.60 t·hm^(-2))>litter(1.78 t·hm^(-2))>coarse wood residues(0.13 t·hm^(-2)).(3)The areas with high carbon density in the forest ecosystem of Qingdao city are mainly distributed in the three major mountainous areas of the north,southeast,and south,while the areas with low carbon density are mainly concentrated in the central plain area.【Conclusion】The carbon density of the forest ecosystem in Qingdao is slightly higher than the average of Shandong province,but there is still a certain gap with the developed forest areas.In the future,the carbon sequestration capacity of the forest ecosystem in Qingdao can be further improved by strengthening the management of young and middle-aged forests.
