摘　　要：为了解不同优势树种组在不同时期的碳储量和碳密度,以广西国有黄冕林场各优势树种为研究对象,通过生物量扩展因子法,估算了黄冕林场森林固碳能力。结果表明:(1)黄冕林场2014年、2019年总碳储量分别是562040.09 t和826000.61 t,2019年比2014年增加了47.0%,其中一般阔叶树的碳储量最大;(2)杉木类、松类、速生桉和一般阔叶林的碳密度随着龄级的增加逐渐增大,2019年比2014年分别增加了21.7%、61.2%、22.1%和41.3%,且杉木类、松类、一般阔叶林在过熟林时碳密度达到最大值,而速生桉则在近熟林时最大;(3)杉木类、松类、一般阔叶林的碳储量随着龄级的增加逐渐增大,在过熟林时碳储量最大,而速生桉则在近熟林时最大。In order to understand the carbon storage and carbon density of different dominant tree species groups in different periods,the dominant tree species in Huangmian Forest Farm of Guangxi were taken as the research objects,and the forest carbon sequestration capacity of Huangmian Forest Farm was estimated by biomass expansion factor method.The results showed as the following three aspects.(1)The total carbon reserves of Huangmian Forest Farm in 2014 and 2019 were 562040.09 t and 826000.61 t respectively.In 2019,it increased by 47.0%compared with 2014,and the carbon reserves of general broadleaf trees were the largest.(2)The carbon density of Chinese fir,pine,fast-growing eucalyptus and general broad-leaved forests increased gradually with the increase of age class,and the carbon density in 2019 increased by 21.7%,61.2%,22.1%and 41.3%,respectively,compared with that in 2014.The carbon density Chinese fir,pine and general broad-leaved forests reached the highest value in over-mature forest,while that of fast-growing eucalyptus was the highest in near-mature forest.(3)The carbon reserves of Chinese fir,pine and general broad-leaved forests increased gradually with the increase of age class,and the carbon reserves of over-mature forest were the largest,while those of fast-growing eucalyptus were the largest in near-mature forest.
