Carbon Reserve and Carbon Sink Potential Estimation of Mangrove in Guangdong Province
[Introduction]The mangrove ecosystem has a high carbon sequestration capacity and is an important part of the global carbor cycle.Exploring its carbon sink potential can promote the mitigation and adaptation to climate change,providing a potential marine solution for China's carbon peak and carbon neutralization.[Method]In this study,the methodology of mangrove blue carbon assessmen was studied to estimate the carbon reserve and carbon sink potential in Guangdong Province.The carbon reserve in mangroves ir Guangdong Province was about 3 222.035 kt C,of which the carbon reverse in vegetation was about 1 094.465 kt C and the carbor reserve in soil was about 2 127.57 kt C.Among different mangrove communities,the vegetation carbon reserve of Aegicerai corniculatum was the highest,reaching 1 508.931 kt C,followed by Avicennia marina,Kandelia obovata and Sonneratia apetala,with carbon reserve of 1 508.931 kt C,859.115 kt C,193.296 kC and 660.693 kt C respectively.[Result]According to the"Special Actior Plan for Mangrove Protection and Restoration(2020-2025)",by 2025,55.00 km2 of mangroves will be planted in Guangdong Province and the carbon sink potential can increase by 36.171 kt CO2-e～99.891 kt CO2-e,with great carbon sink potential.[Conclusion]This study can provide scientific basis for the afforestation of mangrove carbon sink in Guangdong Province,and is of great significance foi China's carbon peak and carbon neutrality cause.
