在阐述森林碳汇概念及碳汇计量方法的基础上,运用材积源生物量法(Volume—biomassmethod)对东江源区森林系统碳储量进行估算。结果表明:总碳储量为45.11×10^6tC,其中森林植被层碳储量为9.17×10^6tC、森林植被枯落物层碳储量为0.94×10^6tC、森林土壤层碳储量为35.0×10^6tC。运用蓄积、面积估算结果是:总碳储量为40.89×10。tC,其中林分生物量碳储量4.13×10^6tC,竹林生物量碳储量0.21×11010^6tC,经济林碳储量0.61×10^6tC,枯落物层和土壤层碳储量不变。最后得出东江源区森林系统总碳储量值43x10^6tC,东江源区森林系统碳交易潜在价值约合28亿美元。以此,提出了建立东江源区绿色基金会的构想。
Based on the explanation of the concept of forest carbon sink and the methods of carbon measure ment, this article estimated the carbon reserve forest system by using two methods in the riverhead of Dongjiang. Volume-biomass calculation (VBC) showed that the total carbon reserve was 45.11 million tC, among which the carbon reserves of forest vegetation layer, litter layer, and soil layer were 9.17, 0.94, and 35.0 million tC, respectively. Volume and area calculation showed that the total carbon storage was 40.89 miUion tC, among which the carbon storages of forest, bamboo forest, economic forest were 4.13, 0.21, and 0.61 million tC. Litter and soil carbon storages were the same as those estimated by VBC. Fi nally the conclusion is that total forest carbon sink was 43 million tC, potentially price was about S 2.8 billions in Dongjiang riverhead. Based on the above analysis, the suggestion of the establishment of the Green Foundation in Dongjiang riverhead was put forward.
