摘要
碳汇价值的测算是CDM碳汇项目顺利实施的核心和技术关键之一。文章在利用生长曲线、生物量换算因子法和市场价格法,从生态效益和经济效益两个维度,动态预测了川西北CDM碳汇项目未来10年内碳汇价值的变化,分析了面积和树种因素对于碳汇能力的影响。结果表明:该项目碳汇价值逐年上涨,上涨速率受到树木生长影响逐年降低,大规模的碳汇林能够增加碳汇的外延能力,但会降低单位面积的碳汇能力,树种类别对碳汇价值的影响受到生长曲线、生物量转换因子等多方面的影响。
Calculation of the value of carbon sequestration is one of the core and the key technology of carbon se- questration of CDM project implementation. Growth curve, this paper in the use ofbiomass conversion factor meth- od and market price method, from the two dimensions of ecological benefits and economic benefits, the dynamic prediction of changes within the next 10 years the value of carbon sequestration in Northwest Sichuan CDM carbon sequestration projects, analyzed the influence factors of area and species for carbon sequestration capacity. The results show that： the project of carbon sequestration value rose year by year, rising rate of growth of trees affected by re- duced year by year, large- scale carbon sink forest can increase the extension capability of carbon sequestration, but reduces the unit area of carbon sequestration, affect the species category of carbon sequestration value is influenced by the growth curve and the biomass conversion factor etc.
