摘要：【目的】森林公园是我国自然保护地体系和森林资源管理的重要组成部分。在未来碳中和目标下,国家森林公园植被生产力和碳汇特征的分析,对于明确森林公园的碳汇贡献和未来森林碳汇管理具有重要意义。【方法】采用生态系统过程模型CEVSA2,模拟1982—2017年中国881处国家森林公园的净初级生产力(NPP)和净生态系统生产力(NEP)的空间分布特征。【结果】国家森林公园NPP总量为62.67 Tg C·a^(?1),年均NPP表现为从东南向西北递减的趋势,其中35.5%的国家森林公园年均NPP分布在700~900 g C·m^(?2)·a^(?1)之间。国家森林公园碳汇总量为5.06 Tg C·a^(?1),年均NEP表现为华中地区和东北地区相对较高,华北西部和西北地区相对较低的空间分布特征。97.3%的国家森林公园表现出碳汇效应,东北和西南地区的国家森林公园植被生产力和碳汇最高。【结论】国家森林公园在森林碳汇管理中有很重要的地位,加强对国家森林公园碳汇功能和固碳潜力的综合评估,不仅有助于促进国家森林公园的碳汇管理,也为我国自然保护地体系保护成效的总体评估提供方法借鉴和参考。
【Objective】Forest parks are the important parts of nature reserve system and forest resource management in China.Under the goal of carbon neutralization in the future,the analysis of vegetation productivity and carbon sink characteristics of national forest parks has great significance for clarifying the carbon sink contribution of forest parks and future forest carbon sink management.【Method】In this paper,the ecosystem process model—CEVSA2 was adopted to simulate the spatial distribution of net primary productivity(NPP)and net ecosystem productivity(NEP)in 881 national forest parks in China from 1982 to 2017.【Result】The total NPP of national forest parks was 62.67 Tg C·a^(-1),and the average annual NPP decreased from southeast to northwest.The average annual NPP of 35.5%of the national forest parks was distributed in the range of 700~900 g C·m^(?2)·a^(-1).The total carbon sink of national forest park is 5.06 Tg C·a?1,and the average annual NEP of spatial distribution characteristics are relatively high in central China and northeast China,while relatively low in the western part of north China and northwest China.97.3%of the national forest parks showed net carbon sequestration effect.National forest parks in the northeast and southwest China have the highest vegetation productivity and carbon sink.【Conclusion】National forest parks play an important role in forest carbon sequestration management.Strengthening the comprehensive evaluation of carbon sequestration function and carbon sequestration potential of national forest parks will not only help to promote carbon sequestration management of national forest parks,but also provide method reference for the overall evaluation of the protection effectiveness of China's nature reserve system.
