摘　　要：基于福建省森林资源2020年度监测数据,分析福州市森林碳储量及碳密度格局分布特征,为福州市森林固碳能力提升和森林资源科学经营管理提供参考依据。福州市森林总生物量为5016.87×10^(4) t,单位面积生物量66.88 t/hm^(2),乔木林生物量为4433.30×10^(4) t,占总生物量的88.37%;福州市森林碳储量达到2454.06×10^(4) t,乔木林碳储量为2191.45×10^(4) t,占碳储量的89.30%;乔木林碳储量组成中阔叶林比例最大58.34%,其次马尾松为25.17%。福州市森林平均碳密度为32.72 t/hm^(2),各森林类型碳密度27.43~54.73 t/hm^(2),阔叶林最高为54.73 t/hm^(2),杉木林最低为27.43 t/hm^(2);乔木林面积、碳储量以中龄林、成过熟林为主,碳密度随着林龄、地区GDP增加而呈现增长的趋势,天然林较人工林具有更强的固碳能力。福州市森林以中龄林、成过熟林为主,碳密度水平较低,森林生物量和碳储量增长具有较大的潜力。为此,需进一步加强森林资源保护和科学经营管理,促进林分结构优化调整,增强森林生态系统碳汇能力。Based on the annual monitoring data of forest resources in Fujian Province in 2020,the distribution characteristics of lorest carbon storage and desting pattern in Fuzhou City were analyzed,which provided reference for the improvement of forest carbon sequestration capacity and scientific management of forest resources in Fuzhou City.The total biomass of forest ecosystem in Fuzhou City was 5016.87×10^(4) t,the biomass per unit area was 66.88 t/hm^(2),and the biomass of arbor forest was 4433.30×10^(4) t,accounting for 88.37%of the total biomass.The forest carbon storage in Fuzhou reached 2454.06×10^(4) t,the carbon storage of arbor forest was 2191.45×10^(4)t,the average carbon density was 32.72 t/hm^(2),and the carbon density of each forest type was 27.43~54.73 t/hm^(2).The hightest carbon densit y of broad leaved forests was 54.73 t/hm^(2),and the lowest carbon density of Cunninghamia lanceo lata(Lamb.)Hook.was 27.43 t/hm^(2).The area and carbon storage of arbor forest were mainly middle-aged forest and mature forest.The carbon density showed an increasing trend with the increase of forest age.The carbon density of broad-leaved forest was higher than that of coniferous forest.The forests in Fuzhou City are mainly middle-aged forests and mature and over-mature forests.The carbon density level is low,and the growth of forest biomass and carbon storage has great potential.Therefore,it is necessary to further strengthen the protection of forest resources and scientific management,promote the optimization and adjustment of forest structure,and enhance the carbon sink capacity of forest ecosystem.
