摘要: 为科学评估生态保护与修复工程的实施效果,研究生态保护修复碳汇成效监测技术方法至关重要。本文以洞庭湖区域山水林田湖草沙一体化保护和修复工程为研究对象,构建了遥感数据驱动的“天-空-地”一体化碳汇监测方法,系统评估了2023年与2024年的植被碳储量、土壤碳储量,以及典型样地修复前后的碳汇量,并分析了空间分布特征。结果表明:①植被碳储量从233.24万t增至688.14万t,土壤碳储量从940.78万t增至1 316.61万t;②植被碳储量与土壤碳储量呈“西高东低”的空间分布格局;③典型样地修复前后全年碳汇量从669.78 kg CO2增至1 231.36 kg CO2。本文为大型生态修复工程的碳汇成效监测提供了技术参考,可为长江经济带生态保护修复提供科学依据。

Abstract: To scientifically evaluate the implementation effects of ecological protection and restoration projects,it is crucial to study monitoring techniques for the carbon sink effectiveness of ecological protection and restoration.This paper takes the integrated protection and restoration project in the Dongting Lake region as the research object,and constructs a “space-air-ground” integrated carbon sink monitoring method driven by remote sensing data.It systematically assesses the vegetation carbon storage and soil carbon storage in 2023 and 2024,as well as the carbon sink capacity before and after the restoration of typical sample plots,and analyzes the spatial distribution characteristics.The results show that:①The vegetation carbon storage increased from 2.332 4 million tons to 6.881 4 million tons,and the soil carbon storage increased from 9.407 8 million tons to 13.166 1 million tons.②The vegetation carbon storage and soil carbon storage show a spatial distribution pattern of being higher in the west and lower in the east.③The annual carbon sink capacity of the typical sample plot increased from 669.78 kg CO2 to 1 231.36 kg CO2 before and after restoration.This paper can provide technical reference for the carbon sink effect monitoring of large-scale ecological restoration projects and provide scientific basis for the ecological protection and restoration of the Yangtze River Economic Belt.
