摘要
区域尺度陆地生态系统固碳速率和潜力定量认证的方法及其不确定性分析是国家应对气候变化的重要基础工作。目前国内外对于陆地生态系统碳汇以及增汇潜力计量方法已经开展了大量的研究,提出了温室气体排放清单的计量方法,CDM(清洁发展机制)造林再造林项目碳汇的计量方法,以及土地利用变化碳汇计量等方法,国家温室气体清单的方法仅适用于国家范围的碳汇计量,对于区域碳汇计量却十分粗略。CDM造林再造林项目仅局限于森林管理等项目,而未涵盖将来可能列入碳汇目标的其它生态系统增汇管理措施。目前,关于森林、草地、农田等区域尺度生态系统碳汇计量还没有形成统一的、标准化的方法体系。本文对IPCC国家尺度的碳排放和陆地增汇技术评估方法体系、土地利用对陆地碳源汇影响的评价方法、以及人为管理措施下陆地生态系统增汇效应计量方法进行了详细的阐述,并对每种计量方法的不确定性进行分析,期望为中国陆地生态系统固碳速率、增汇潜力的计量、报告、认证和核查方法论和技术体系的建立提供依据。
Carbon inventory certified methods of carbon sequestration rate and potential in terrestrial ecosystem at region scale and their uncertainty analysis are the scientific foundational work of taking practices to mitigat-ing the global warming potential.A large number of studies have been carried out on the measuring methods of the terrestrial ecosystem carbon sink and the carbon sequestrating potential,and the national greenhouse gas in-ventory methods,CDM（Clean Development Mechanism projects） afforestation and reforestation project meth-ods,carbon inventory method in land-use and land-cover change and some other methods were proposed.Na-tional greenhouse gas inventory was applicable to state-wide measurement of carbon sequestration,and was not suitable for regional carbon inventory.CDM afforestation and reforestation project focused on the carbon seques-tration potential of forest management,and did not take the practices of increasing carbon sinks carried on other ecosystems into account.To date carbon sequestration measurement for forest,grassland,farmland and other re-gional-scale of ecosystems do not have a uniform and standardized methodology yet.In this paper,we first intro-duced national greenhouse gas inventory methods,CDM afforestation and reforestation project methods,car-bon inventory method in land-use and land-cover change and analysis their uncertainty in detail.Then we pro-posed a carbon inventory method applicable to farmland,grassland,forests and other terrestrial ecosystems,aim-ing to provide scientific basis for establishing the methodology for measuring,reporting,and verifying the car-bon sequestration rate and potential in regional terrestrial ecosystems.
