竹材碳足迹内涵及其对产业发展的调控作用

植物是陆地上唯一能够从大气中固碳的自然生态系统，其减缓气候变化、改善人类生活质量的能力远未被认识和充分发挥。竹子是世界上生长最快的植物之一，固碳潜力巨大，一次种植可永续利用。竹子从光合作用、生长发育、采伐收获、产品制造、友好利用直至分解释放的全生命周期过程，是碳汇或碳封存的全过程，即竹材碳足迹。通常研究的竹林碳汇只涉及竹林生长阶段，忽略产品使用阶段，以及相互之间的联系。开展竹材碳足迹的全过程系统监测和研究，完善竹林碳汇的内涵，正确认识碳循环规律，是当前全球气候变暖背景下碳汇研究的必由之路；特别是在竹材碳足迹的理论指导和政策实施之下，促进竹林定期采伐、全量收获、健康生长，促进竹产品量产利用，增加产品碳封存时间、提高产品寿命，促进资源高效利用、脱贫增收致富、延缓碳排放，调控全生命周期各个环节合理有序、协同发展，意义更加重大。竹材碳足迹理念的实施对系统认识竹林碳汇、指导竹林健康生长、提高产品产量和质量、推进竹业全产业链发展、减少二氧化碳排放，具有重要学术价值和实用价值。

Connotation of Bamboo Carbon Footprint and Its Regulating Effect on Bamboo Industrial Development

Plants are the only natural ecosystem that is capable of sequestering carbon from the atmosphere, and its ability to mitigate climate change and improve the quality of human life is far from fully understood. Bamboo, as one of the fastest growing plants in the world, has great carbon sequestration potential and can be sustainably used with single planting. The whole life cycle of bamboo from photosynthesis through growth, harvesting, product manufacturing and friendly utilization to decomposition and release is the whole process of carbon sink or carbon sequestration, namely the carbon footprint of bamboo. The carbon sink of bamboo forest usually studied only involves the growth stage of bamboo forest, while the role of bamboo products in emission reduction as well as the link between the product and emission reduction has been often ignored. It is necessary to carry out systematic monitoring and research on the whole process of bamboo carbon footprint, to improve the connotation of bamboo sink and correctly understand the law of carbon cycle. Under the theoretic guidance of bamboo carbon footprint and with the policies implemented, it is of great significance to enhance the regular and all-amount bamboo harvest by ensuring the growth of bamboo forest, to increase the production of forest products, to prolong the carbon sink time by improving the lifespan of bamboo forest, to promote the efficient utilization of bamboo resources for income increase and slower process of carbon emission and to regulate the whole life cycle for ensuring the coordination and synergy development of all parts. The implementation of the bamboo carbon footprint concept is of great academic and practical value in systematically understanding bamboo forest sink, guiding the healthy growth of bamboo forest, improving the product yield and quality, promoting the development of the whole bamboo industry chain, and reducing the carbon emissions.
