粤北常绿阔叶林碳计量与评价——以天井山为例

Carbon Accounting and Evaluation for Evergreen Broadleaved Forest in North Guangdong ——Take Tianjingshan for Example

本文利用外业调查所取得的数据,采用蓄积量—生物量经验公式对天井山样地林分进行生物量密度和碳密度估算,并用造林成本法和碳税法对该样地进行碳储量价值估算评价。结果表明:(1)天井山样地林分的生物量密度为248.93mg/hm2,用生物量与碳转换系数为0.5的生物量—碳储量公式转换为林分碳密度为112.02Mg/hm2。(2)用造林成本法和碳税法平均值估算出该样地的碳储量价值为145277.5元。

In this paper, we used the the data from field investigation and the volume - biomass empirical formula to estimate biomass density and carbon density of plot stand in Tianjingshan. And we took the cost of afforestation and carbon tax to estimate the value of carbon storage of this kind of stand. Results showed that： （ 1 ）The biomass density was 248.93mg/hm2. The carbon density was 112. 02Mg/hm^2/by using the biomass - carbon storage equation with taking the conversion factor as 0. 5. （2） The value of carbon storage was 145277.5 yuan by taking the mean of cost of afforestation and carbon tax.
