| 摘 要： | 目的]通过制定森林管理参考水平,计量并核算森林管理活动的合格净碳汇清除量。方法]采用核证减排标准中农业、林业和其他土地利用项目的自愿碳标准,选取其中改善森林管理的项目方法学标准,并结合不可抗力及湖南会同县的杉木人工林林地资源现状,进行计量和核算湖南会同县杉木人工林的合格碳汇量。该方法学标准包括4个碳库,即地上部分、地下部分、枯死木和木质林产品。结果]对30年生和23年生杉木人工林进行森林管理活动后,林分碳储量变化量和碳汇量都有明显增加。森林管理参考水平在考虑皆伐的碳排放后的净碳汇量为-82.79 t二氧化碳当量·hm~(-2),30年生和23年生的总碳汇量分别为441.00、715.46 t二氧化碳当量;实际合格总碳汇量分别为606.59、881.06 t二氧化碳当量。结论]不同的森林管理采伐强度对30年生和23年生林分碳汇量的影响差异显著。本文分别基于湖南会同森林生态实验站第1代杉木人工林建立参考水平和生态站2代杉木人工林制定参考水平核算会同县杉木人工林碳汇量,结果是基于后者参考水平核算的会同县杉木人工林合格的碳汇量比基于前者参考水平核算的多30 t二氧化碳当量·hm~(-2)。

| Abstract: | Objective] By determining the forest management reference level to measure and account the eligible carbon sink. Method] Using the methodology of Improved Forest Management in Voluntary Carbon Standard for Agriculture, Forestry and Other Land Use Projects (AFOLU-VCS) to account the carbon stock and sink of Huitong of Hu''nan Province. Four carbon stocks in aboveground, underground, dead wood and wood products of Chinese fir (Cunninghamia lanceolata) planted in 1983 and 1990 were estimated, and the force majeure was also taken into consideration. Result] A comparison on the Chinese fir plantation planted in 1983 and 1990 shows that the carbon stock change and carbon sink significantly increase after forest management activities. The eligible carbon sinks of Chinese fir plantation planted in 1983 and 1990 are 606.59 t CO2-eq and 881.06 t CO2-eq, respectively. The effects of forest management intensity on the carbon sink of 30-years-old and 23-years-old stands are significantly different. Conclusion] Based on the data of first-and second-generation Chinese fir plantation in Huitong Forest Ecological Experiment Station, the reference level to account the carbon sink is established. The result showed the eligible carbon sink of the latter is 30t CO2-eq·hm-2 higher than that of the former. |
