摘要：以全国林业应对气候变化碳汇计量监测体系建设结果数据为基础,应用森林碳库专项调查建立的碳计量模型和参数,结合历次森林资源清查成果等数据,估算了2020年长江经济带林地和其他生物质碳储量和碳汇量。研究表明:(1)2020年长江经济带林地碳储量24543.58 Tg C(其中森林植被碳储量为4372.85Tg C),散生木和四旁树等其他生物质碳储量329.59 Tg C。2020年长江经济带林地碳汇量81.81 Tg C/a(300.26Tg CO/a)、散生木和四旁树等其他生物质碳汇量6.60 Tg C/a(24.21 Tg CO/a)。无论是林地和其他生物质碳储量、碳汇量、还是森林植被碳储量,乔木林地所占比例最大(69%—85%);长江经济带11个省市中,云南省最大,上海市最小;林地碳储量中土壤有机质碳库贡献最大(81.46%),林地碳汇量中生物量碳库贡献最大(90.99%);林地碳汇量中“一直为林地的土地”产生碳汇量贡献最大(71.74%),其中一直为乔木林的土地产生的碳汇量占69.89%;(2)阐述了长江防护林工程、天然林资源保护工程、珠江防护林工程和沿海防护林工程4大重点生态工程对长江经济带碳储量和碳汇量的贡献,长江防护林工程贡献率最大(81%—83%),其次是天然林资源保护工程(32%—38%),珠江防护林工程和沿海防护林工程影响较小。分析了人工造林、中幼林抚育、次生林和低效林改造、退化林修复等生态保护修复措施对长江经济带碳储量和碳汇量的贡献,并提出了碳中和愿景下森林固碳增汇的有效途径。
Based on the data of carbon measurement and monitoring system of China′s forestry addressing climate change,carbon storage and carbon sink of forest land and other biomass in the Yangtze River Economic Belt in 2020 were estimated by using the carbon measurement model and parameters established by the specific survey of forest carbon pools,also combining the previous national forest inventory data.The results showed that:(1)In 2020,the total carbon storage of forest land in the Yangtze River Economic Belt was 24543.58 Tg C(including 4372.85 Tg C of carbon storage of forest vegetation),and the carbon storage of other biomass such as scattered trees and four-side trees was 329.59 Tg C.In 2020,the carbon sink of forest land in the Yangtze River Economic Belt was 81.81 Tg C/a(300.26 Tg CO/a),and the carbon sink of other biomass such as scattered trees and four-side trees was 6.60 Tg C/a(24.21 Tg CO/a).The arbor forestland accounted for the largest proportion(69%—85%)of the total carbon storage or carbon sink of forest land as well as forest vegetation.Among all 11 provinces and cities in the Yangtze River Economic Belt,the carbon storage or carbon sink of Yunnan Province took the 1place,while Shanghai was the last.For forest land carbon storage,soil organic matter contributed the most(81.46%),while biomass contributed the most(90.99%)to forest land carbon sinks.‘Land that has always been forest land′contributed the most to forest land carbon sinks(71.74%),of which the carbon sink generated by the land that has always been arbor forest accounted for 69.89%.(2)The contribution of four key ecological projects(namely,the Yangtze River Shelterbelt Project,the Natural Forest Protection Program,the Pearl River Shelterbelt Program and the Coastal Shelterbelt Project)to the carbon storage and carbon sinks in the Yangtze River Economic Belt was expounded.Among the four key ecological projects,the Yangtze River Shelterbelt Project made the largest contribution(81%—83%),followed by the Natural Forest Protection Program(32%—38%),while the Pearl River Shelterbelt Program and the Coastal Shelterbelt Project had less impact.In addition,the contribution of ecological protection and restoration measures to carbon storage and carbon sinks of the Yangtze River Economic Belt was analyzed,including plantations,young and middle-aged forest tending,secondary forest and low-efficiency forest transformation,and degraded forest restoration.An effective path was proposed to enhance forest carbon storage and carbon sinks under the carbon neutral vision.
