虎山林场重点生态公益林碳汇计量研究

Measurement on Carbon Sequestration in Key Ecological Forest in Hushan Forest Farm

在虎山林场重点生态公益林内设置标准地,利用生物量法对标准地内乔木树种的干、枝、叶、根的固碳量分别计量,对标准地内枯枝落叶及土壤的固碳量分别计量。结果表明,固碳量与生物量成正比,并以树干、树枝、树根、树叶的顺序由高到低排列。虎山林场重点生态公益林的生物固碳量为38.89t·hm-2,土壤固碳量为87.51t·hm-2,碳总量为126.40t·hm-2。

Standard plots were set in key ecological forest in the Hushan Forest Farm.Carbon sequestration of bran-ches,leaves & roots in the standard ground by using biomass method was measured respectively;litter & soil car-bon sequestration in standard plots were measured respectively.Result shows that carbon sequestration is propor-tional to the biomass.The descending order is the trunk,branches,roots and leaves.The biological sequestration, soil carbon sequestration & the total amount of carbon of the key ecological forest is 38.89 t ?hm-2 ,87.51 t ?hm-2& 126.40 t ?hm-2 ,respectively.
