福建顺昌县国有林场毛竹林可持续经营碳汇计量

Carbon Accounting for Sustainable Management of Moso Forest in Shunchang State-owned Forest Farm, Fujian Province

依据《竹林经营碳汇项目方法学》对顺昌县国有林场的2 278.5 hm^2毛竹林通过改进传统经营方式在6年(3个大小年)内产生的碳汇进行计量。结果显示,毛竹林年均项目减排量为25 563 t CO2-e,并成功实现了竹林碳汇交易。竹林碳汇交易的实践表明,要达到毛竹碳汇计量标准实现碳排放权交易,必须改变传统经营方式,将毛竹收获年龄从3度竹延长到4度(含)以上,优化竹林径阶结构和空间结构,使竹林结构达到稳定可持续状态,从而实现社会经济效益与环境目标统一。

The study calculates the carbon sink of 2 278.5 ha Moso bamboo forest in Shunchang County State-owned Forest Farm in 6 years(3 on-years plus 3 off-years), which has applied the improved traditional management in accordance with the Carbon Sequestration Project Methodology for Bamboo Forest Management. The results show that the average carbon emission of the Moso bamboo forest has been reduced by 25 563 t CO2-e, which has been successfully transacted in the carbon market. The practice of bamboo forest carbon sequestration in Shunchang indicates that the traditional management must be improved and modified in order to reach the bamboo carbon accounting standards. The age of harvest should be extended from the sixth year to eighth year, while the bamboo forest stand diameter structure and spatial structure should be optimized to establish a spatially stable and sustainable forest stand structure, which can achieve the coordinated socioeconomic and environmental benefits.
