中国自然保护地碳中和贡献的初步评估及三个关键研究课题

The Preliminary Assessment and Three Key Issues of Carbon Neutrality Contribution of Protected Areas in China

自然保护地不仅对保护生物多样性具有重要意义,也在减缓气候变化、实现碳中和目标方面起到关键作用。中国自然保护地的碳中和贡献尚未得到充分的认识和关注,相关研究尚处于起步阶段。首先对中国陆域自然保护地的碳储量、碳吸收能力、人为碳排放水平展开初步评估,发现陆域自然保护地在保护高碳中和贡献生态系统方面存在不足。随后提出了中国自然保护地碳中和贡献研究的3个关键课题,分别是自然保护地碳循环作用机理研究、自然保护地碳中和贡献评估与管理、生物多样性保护和碳中和的协同治理。最后围绕关键课题提出14个具体研究问题,为中国自然保护地减缓气候变化的科学研究与管理实践构建系统框架。

Protected areas(PAs)are not only important for biodiversity conservation,but also play a key role in mitigating climate change and achieving carbon neutrality.The contribution of PAs to carbon neutrality in China has not yet been fully recognized and paid attention to,and relevant studies are still in the initial stage.This paper firstly assesses the carbon storage,carbon capture capacity and anthropogenic carbon emission level of terrestrial PAs in China,finding the gaps in the conservation of ecosystems with high carbon neutrality contribution.Then this paper proposes three key issues for the study of carbon neutrality contribution of PAs in China,namely,the mechanism of carbon cycling in PAs,the assessment and management based on carbon neutrality contribution,and the synergistic management of biodiversity conservation and carbon neutrality.In addition,14 specific research questions are proposed around the key issues.In this way,this paper develops a systematic framework for scientific research and management practices of climate change mitigation in China's PAs.
