| 摘要: |
| 二氧化碳浓度在全球范围内的持续升高，使得气候变化问题成为 21 世纪突出的环境议题，沿海生态系统的“蓝碳”逐渐受到重视。海草床如同海洋的“绿色森林”，是近岸高生产力的生态系统，蕴藏着巨大的碳汇潜力，成为“蓝碳”的重要组成部分。通过采用实地采样和实验 测量的方法，文章对曹妃甸海草床碳储量进行了定量估算，并系统分析了估算过程中的不确定性来源，结果表明：（1）基于 2024 年 6 月 GF-2 遥感影像数据，采取人工目视解译、无人机航拍及船舶走航圈定河北省曹妃甸海草床面积 42.82 km2；（2）海草种类为鳗草（原名大叶藻），海草高
度范围为 60 ～ 103 cm，盖度范围为 10 ％～ 60 ％ ；（3）海草床植物生物量碳密度的变化范围为
0.05 ～ 0.19 Mg C/hm2，沉积物碳密度范围为 14.27 ～ 31.12 Mg C/hm2；（4）2024 年海草床生物量碳储量为 490 t，沉积物碳储量为 8.89×104 t，海草床总碳储量为（8.94±2.32）×104 t。 |

| Abstract: |
| With the continuous increase of global carbon dioxide（CO2）concentration，climate change has become the most prominent environmental issue faced by human beings in the 21st century，and the“blue carbon”of coastal ecosystems has gradually attracted attention．Seagrass beds are one of the near-shore highly productive ecosystems with great potential for carbon storage and are an important component of“blue carbon”．Through field sampling and experimental measurement，this study quantitatively estimated the carbon storage of seagrass beds in Caofeidian，and systematically analyzed the sources of uncertainty in the estimation process．The results show that：（1）Based on GF-2 remote sensing image data in June 2024，the area of 42.82 km2 of seagrass bed in Caofeidian，Hebei Province was defined by manual visual interpretation，UAV aerial photography and ship surveying．（2）The seagrass species is Eelgrass（formerly known as grass wrack）；the height range of seagrass is 60 ～ 103 cm．and coverage ranges from 10％ to 60％．（3）The biomass carbon density of seagrass beds varied from 0.05 ～ 0.19 Mg C/hm2，and the sediment carbon density ranged from 14.27 ～ 31.12 Mg C/hm2．（4）In 2024，the biomass carbon storage of seagrass bed was 490 tons，the sediment carbon storage was 8.89×104 tons，and the total carbon storage of sebaceous grass bed was
（8.94±2.32）×104 tons. |
