摘　　要：祁连山国家公园不仅是我国西部生态安全的重要屏障,而且也是陆地生态系统固碳增汇的重要区域.由于生态系统分布较广、类型多样,加之气候变化和生态修复等人类活动的影响,目前祁连山国家公园碳储量估算存在很大不确定性,重要生态建设工程、林草资源可持续经营管理的碳汇效应评估滞后.本文通过综述祁连山国家公园林草碳汇最新研究进展,提出3点巩固提升祁连山典型生态系统的碳汇功能的对策建议.首先,应加强林草生态系统固碳机制与抚育管护措施碳汇效应研究.其次,重视天然林草资源的退化修复与可持续经营,积极做好林区病虫鼠害防治.最后,优先选择固碳能力强的造林树种,大力倡导混交造林模式.Qilianshan National Park is not only an important barrier for ecological security in western China,but also an important area for carbon sequestration in terrestrial ecosystems.Due to the wide distribution and diverse types of ecosystems,coupled with the impact of human activities such as climate change and ecological restoration,there is great uncertainty in the estimation of carbon stock in Qilianshan National Park.The assessment of carbon sequestration effects of important ecological construction projects and sustainable management of forest and grass resources lags behind.This paper summarizes the latest research progress of forest and grass carbon sequestration in Qilianshan National Park,and puts forward three countermeasures and suggestions to consolidate and enhance the carbon sequestration function of typical ecosystems in Qilian Mountain.Firstly,it is necessary to strengthen research on the carbon sequestration mechanisms of forest and grass ecosystems and the carbon sequestration effects of nurturing and management measures.Secondly,attention should be paid to the restoration and sustainable management of degraded natural forest and grass resources,with active efforts made to prevent and control pests,diseases,and rodent infestations in forest areas.Finally,priority should be given to selecting tree species with strong carbon sequestration capabilities,and mixed afforestation models should be vigorously advocated.
