| 摘要: |
| 为剖析淤泥质岸滩碳密度特性，估算岸滩碳储量，本研究以河北省沧州市淤泥质岸滩为研究区域，将其划分为6个工作区，布设植被、沉积物碳储量调查点，测定容重、有机碳含量等指标，对碳密度分布、碳储量进行调查与评估。结果表明，沧州市淤泥质岸滩6个工作区之间的沉积物总有机碳含量、干容重存在显著性差异，碳密度分层空间差异明显。淤泥质岸滩总碳储量为641 505.43 t C，第Ⅳ工作区碳密度(55.99 g/m2)最高,第Ⅴ工作区碳储量(138 237.11 t C)最高。同时，沧州市淤泥质岸滩碳密度明显低于红树林、盐沼等典型滨海生态系统，但其部分区域碳密度略高于唐山市淤泥质岸滩碳密度。本研究成果可为后期提升沧州市碳储能力提供理论数据和基础研究。 |

| Abstract: |
| To analyze the carbon density characteristics of muddy tidal flat and estimate its carbon storage,this study focused on the muddy tidal flat in Cangzhou City,Hebei Province.The muddy tidal flat was divided into six workspaces,where survey points for vegetation and sediment carbon storage were arranged.Indicators such as bulk density and organic carbon content were measured,and distribution of carbon density and carbon storage were investigated and estimated.The results indicated that there were significant differences in total organic carbon content and dry bulk density of sediments among the six workspaces of the muddy tidal flat in Cangzhou City,with obvious spatial differences in carbon density stratification.The total carbon storage was 641 505.43 t C.The carbon density (55.99 g/m2) in workspace Ⅳ was the highest,and the carbon storage (138 237.11 t C) in workspace Ⅴ was the highest.The carbon density in the muddy tidal flat area of Cangzhou City was significantly lower than that in typical coastal ecosystems such as mangrove and salt marsh,while the carbon density in the part of area was higher than that in the muddy tidal flat area of Tangshan City.The findings of this study provide theoretical data for enhancing the carbon storage capacity of Cangzhou City in the future. |
