区域木竹制品储碳效应分析以龙泉市为例

Analysis of Carbon storage effect of bamboo and wood products in Longquan

  • 摘要:
    目的 为全面了解龙泉市林业碳汇的贡献、完善县域森林资源清单、辅助制定可持续管理和优化使用森林资源等森林管理政策,最大限度发挥林业在实现区域碳达峰碳中和目标中的作用。
    方法 基于森林资源、木竹产业现状,测算了龙泉市林木生长阶段的固碳量,估算了林木采伐后产品阶段的储碳效应,并评估了其碳清除贡献。
    结果 结果表明:①截至2020年底,龙泉市乔木林地上部分碳储量610.42万t,竹林地上部分碳储量93.77万t,林木碳储量合计704.19万t,相当于固定了2582.03万t CO2e; ②2021年龙泉市乔木林和竹林地上部分碳汇量为123.54万t CO2e,其中乔木林地上部分生长碳吸收133.83万t CO2e,竹林地上部分碳储量变化量5.13万t CO2e,活立木消耗碳排放15.42万t CO2e;③通过文献资料分析法,估算2021年龙泉市本地材制品的碳储量为12.02万t,可抵消44.07万t CO2e的碳排放,占2021年龙泉市乔木林和竹林地上部分碳汇量的35.67%,其中木制品碳储量为9575 t,可抵消3.51万t CO2e的碳排放,占活立木消耗碳排放的22.76%;④2021年龙泉市本地加工人造板的碳储量为68.10万t,可抵消249.70万t CO2e的碳排放,本地加工的木竹材中至少超过82%来源于外地。
    结论 根据上述研究结果,提出了科学实施森林可持续经营、培育大径材用材林、培育优质高产竹林、促进木竹加工科技成果转化、开展生命周期碳排放核算等固碳增汇减排发展建议。

     

    Abstract:
    Objectives In order to comprehensively understand the contribution of forest carbon sink in Longquan City, improve the county-level forest resource inventory, assist in formulating sustainable management and optimizing forest resource utilization and other forest management policies, and maximize the role of forestry in achieving regional carbon peak and carbon neutrality goals.
    Methods This article calculated the carbon sequestration of forest trees at the growth stage of Longquan City based on the current situation of forest resources and timber and bamboo industries, estimated the carbon storage effect of forest products after logging, and evaluated their carbon removal contribution.
    Results The results showed that: (1) By the end of 2020, the aboveground carbon storage of Longquan's arbor forests was 6 104.2 thousand tons of C, the aboveground carbon storage of bamboo forests was 937.7 thousand tons of C. The total carbon storage of forest trees was 7 041.9 thousand tons of C, equivalent to 25820.3 thousand tons of CO2e. (2) In 2021, the aboveground carbon sequestration of arbor and bamboo forests in Longquan was 1 235.4 thousand tons of CO2e, of which the aboveground carbon sequestration of Arbor and bamboo forests was 1 338.3 thousand tons of CO2e. The aboveground carbon sequestration of bamboo forests was 51.3 thousand tons of CO2e, and standing trees consume 154.2 thousand tons of CO2e. (3)Through literature analysis, it is estimated that in 2021, the carbon storage of Longquan's indigenous products will be 120.2 thousand tons of C, which can offset 440.7 thousand tons of CO2e emissions, it accounted for 35.67% of the aboveground carbon sequestration in Longquan's arbor and bamboo forests in 2021, with wood products accounting for 9.575 thousand tons of C, offsetting 35.1 thousand tons of CO2e emissions, accounting for 22.76% of the carbon emissions from standing trees. (4) In 2021, the carbon stock of the locally processed wood-based panels in Longquan was 681.0 thousand tons of C, which could offset the carbon emissions of 2,497.0 thousand tons of CO2e. At least 82% of locally processed bamboo and wood came from overseas.
    Conclusions According to the above conclusion, some suggestions for carbon sequestration and emission reduction were put forward, such as the scientific implementation of sustainable forest management, cultivating large-diameter timber forests, cultivating high-quality bamboo forests, promoting the transformation of scientific and technological achievements, and carry out life-cycle carbon emissions accounting.
