摘要

巴黎协定》要求签署国提高其国家温室气体清单的透明度。中国的清单利用地面林地测量报告了大量的森林碳增量,但缺乏独立的卫星支持,而且人类管理和人为环境变化(大气中二氧化碳的增长、气候变化和氮沉积)的贡献尚不清楚。在此,我们利用遥感和植被建模研究了 2001 年至 2020 年中国各地木质生物量碳的变化及其驱动因素。我们的研究结果表明,在此期间,森林覆盖率增加了 6.2%(59.2 万公顷),木质生物质碳汇为 208.6 ± 51.8 TgC yr-1,与国家清单一致。森林和林地的保护对观测到的碳汇的贡献出乎意料地大(59.2%),另有 29.4% 来自人为扩展。在这些由管理驱动的汇中,53.7%(99.2 TgC yr-1)归因于直接管理效应,其余 46.3% 归因于环境变化的影响。中国的生态恢复项目占直接管理效应的 73.5%。我们的研究为中国的清单提供了卫星证据,并强调了人类管理在中国木质碳平衡中的关键作用。

Growing biomass carbon stock in China driven by expansion and conservation of woody areas

The Paris Agreement mandates that signatory countries enhance the transparency of their national greenhouse gas inventories. China’s inventories have reported substantial forest carbon gains using ground-based forest plot measurements, but independent satellite-based support for such inventories is lacking and the contributions from human management and anthropogenic environmental changes (atmospheric CO2 growth, climate change and nitrogen deposition) are unknown. Here we use remote sensing and vegetation modelling to investigate the changes in woody biomass carbon and their drivers across China from 2001 to 2020. Our results show a forest cover increase of 6.2% (59.2 Mha) over this period and a woody biomass carbon sink of 208.6 ± 51.8 TgC yr−1, consistent with the national inventories. The conservation of forest and woodland areas made an unexpectedly large contribution (59.2%) to the observed sink, with an additional 29.4% from anthropogenic expansion. Of these management-driven sinks, 53.7% (99.2 TgC yr−1) is attributed to a direct management effect and the remaining 46.3% to the effects of environmental changes. China’s ecological restoration projects contributed 73.5% of the direct management effect. Our study provides satellite-based evidence to support China’s inventories and underscores the crucial role of human management in the nation’s woody carbon balance.
