中国东海区典型海岸带蓝碳生态系统时空变化及其碳储量评估
Spatiotemporal changes and carbon storage assessment of typical coastal blue carbon ecosystems in the East China Sea
摘要
Abstract
In order to study the carbon sequestration capabilities of coastal blue carbon ecosystems represented by mangroves,salt marshes,etc.,this paper uses multi-source and multi-temporal Landsat images,Random Forest algorithms,and InVEST model blue carbon module to evaluate the spatiotemporal distribution characteristics and carbon storage of typical coastal blue carbon ecosystems in the East China Sea during 1992-2022.The results show that:during 1992-2022,in the East China Sea coastal zone,the aquaculture area＞tidal flats area＞salt marshs area＞mangroves area;aquaculture are distributed along the coast of the East China Sea,mangroves mainly distributed in Quanzhou Bay and other areas;salt marshes and tidal flats are mainly distributed in the Yangtze River Estuary-Hangzhou Bay;aquaculture are mainly transformed into water and cultivated land,and tidal flats are mainly transformed into aquaculture and water,salt marshes and mangroves are mainly transformed into aquaculture;during 1992-2022,the typical coastal blue carbon storage in the East China Sea showed an overall upward trend,with an average annual growth rate of 1.26 Tg C/a;the total net carbon sequestration value is 41.61 Tg C.The study results can provide decision-making support and scientific services for the East China Sea coastal zone to formulate measures to reduce emissions and increase sinks,improve carbon sequestration capabilities,and respond to global climate change.关键词
