摘　　要：国家公园在中国生态保护和生态文明建设中扮演着重要角色,其森林资源往往较为丰富,而森林生态系统具有强大的碳汇价值,能够通过光合作用吸收二氧化碳,是缓解气候变化的关键。使用2021年全国森林资源管理“一张图”数据,对中国五个国家公园的森林资源特征及未来碳汇价值进行了分析。研究发现,国家公园森林成、过熟林比例较高、天然林比例较高、宜林地面积较小,缺乏森林碳汇增汇手段,存在泄漏风险。尽管如此,国家公园的森林系统仍具有显著的碳汇价值,据测算,三江源、大熊猫、东北虎豹、海南热带雨林、武夷山这五个国家公园所在县域的未来碳汇量为3.83亿t,经济价值高达45—175亿元。据此,本文建议国家公园通过适度的森林经营来维持森林的碳储存和碳汇功能,并探索森林碳汇的生态价值实现路径,以应对森林老龄化和碳泄漏的风险。In the context of ecological protection and the construction of ecological civilization in China,national parks hold a crucial position.These areas boast abundant forest resources,with forest ecosystems playing a vital role in combating climate change due to their strong carbon sequestration capabilities.Through photosynthesis,they effectively absorb carbon dioxide.This paper utilizes the 2021 National Forest Resource Management“One Map”data to analyze the characteristics and potential future carbon sequestration values of forests within five Chinese national parks.The study reveals that these national parks have a high proportion of mature and over\mature forests,as well as a significant percentage of natural forests.However,the limited area suitable for afforestation constrains methods to increase forest carbon sequestration and poses the risk of carbon leakage.Despite these challenges,the forest systems within these national parks still demonstrate remarkable carbon sequestration potential.It is estimated that the total future carbon sequestration potential in the regions of Sanjiangyuan,Giant Panda,Northeast Tiger and Leopard,Hainan Tropical Rainforest,and Wuyishan national parks amounts to 383 million tons,with an economic value ranging between 4.5 billion to 17.5 billion yuan.Consequently,it is suggested that national parks implement reasonable forest management practices to maintain forest carbon stocks and carbon sequestration functions.Furthermore,it explores ways to realize the ecological value of forest carbon sequestration,addressing challenges posed by forest aging and carbon leakage.
