地表高程监测在滨海蓝碳碳收支评估中的应用

红树林、盐沼和海草床等滨海湿地生态系统是滨海蓝碳的重要组成,其沉积物碳埋藏远高于陆地生态系统,是地球上重要的碳库.沉积物碳埋藏速率(carbon accumulation rate,CAR)是衡量滨海蓝碳生态系统固碳能力的关键指标,其定量测量方法是蓝碳研究的前沿科学问题.文章系统阐述了国内外常用的CAR测定方法,重点综...

APPLICATION OF SURFACE ELEVATION TABLE FOR CARBON BUDGET ASSESSMENTS IN COASTAL BLUE CARBON ECOSYSTEMS

angroves, salt marshes, and seagrass beds are important components of coastal blue carbon, with much higher carbon burials in sediment than those in terrestrial ecosystems. Carbon accumulation rate (CAR) is a key index to evaluate the carbon sequestration capacity of coastal blue carbon ecosystems. This review introduced the principle of a long-term monitoring system, the surface elevation table-marker horizon (SET-MH), and its application in CAR evaluation in coastal wetlands. The SET-MH methods have been globally used in blue carbon sequestration capacity assessment. The establishment of the SET monitoring systems in the coasts of China will obtain in situ data set of surface elevation change and CAR, which will serve for the blue carbon assessments and provide basic information for the national carbon neutrality strategy.
