摘要

摘要: 全球气候变化是当今世界普遍关注的焦点，国内外对竹林生态系统碳汇的研究日益增加，竹林在我国森林植被储碳居于榜首。该文综述了竹林生态系统碳汇的组分、机制研究的已有成果，建议深入研究的方向，为竹林生态系统减排CO₂提供理论依据和技术参考。竹林植株各部分的固碳量是竹秆最大(＞52%)，依次是竹根、竹兜、竹枝、竹鞭和竹叶。竹林与C4能源植物芒草具有相同水平的高生物产量和高光能转化效率，但竹林木质化程度更高，其固碳的数量和质量也就更佳。竹子是需硅量很大的植物，根系从土壤中吸收可溶态硅，促进了硅酸岩矿物的风化并固定大气的CO₂，所以竹林比其他需硅量少的林种具有更大碳汇功能。建议进一步研究的是：深入探讨竹子高光合效率和高碳汇功能的机理；培育和推广植硅体含量高的竹品种；研究竹林土壤中黑炭的固碳机制，使CO₂减排变得更加长期有效。鉴于竹林在固碳减排中的重要作用，发掘和释放竹林碳汇的巨大潜力为森林碳汇减缓全球气候变化提供思路和方法。

Abstract: Global climate change remains a pressing challenge for the world. Research on carbon sink function of bamboo forest ecosystem is gaining momentum within China and abroad. Bamboo forest is top-ranked in term of carbon storage among China's forest vegetation types. In this paper, carbon sequestration component and fixing mechanism were reviewed, and further research direction was suggested to provide theoretical basis and technical reference for carbon sequestration in bamboo ecosystem. Among all parts of bamboo plant, the culm has the largest carbon sequestration capacity, accounting for more than 52% of total, which in turn is followed by root, stump, branch, rhizome and leaf. Compared with Miscanthus (a C4 plant), bamboo has the same high level of biomass production rate and light-energy conversion efficiency. However, the quantity and quality of carbon sequestrated by bamboo are both better than those by the Miscanthus, due to higher lignification of bamboo tissue. Bamboo needs large amount of silicon. Bamboo roots absorb soluble silicon from the soil, which promotes weathering of silicate minerals and consumes more CO₂ as well. Therefore, bamboo forest ecosystem has much larger carbon sequestration capacity via this biogeochemistry pathway than other forest systems with less silicon demand. Proposed future research includes investigating the mechanisms of high photosynthetic efficiency and superior carbon sink function of bamboo, cultivating and popularizing bamboo varieties with high phytolith content, and examining the carbon sequestration mechanism of black carbon in bamboo forest soil to make CO₂ emission reduction more effective in the long term. In view of the important role of bamboo forest in carbon sequestration and emission reduction, exploring and unleashing the huge carbon sequestration potential of bamboo forests may provide ideas and methods for forest carbon sequestration to mitigate global climate change.
