| 摘要: |
| 为剖析滨海盐沼湿地的碳密度特性，评估滨海盐沼湿地的碳密度现状，本研究以典型的渤海辽河口区域滨海盐沼湿地为例，在研究区域开展现场调查，根据盐沼湿地的植被类型、生态特征和地形变化，选取27个采样点，测定植被及土壤样本的生物量、有机碳含量等指标，对不同地物类型土壤和植被的碳密度进行计算，分析盐沼湿地碳密度现状并预估其变化。结果表明，研究区碳密度从大到小依次为光滩区域、盐地碱蓬区域、芦苇区域，平均碳密度分别为166.46、114.83、77.06 t/ha。气候变化导致的海平面上升将极大地降低滨海湿地碳汇潜力。本研究结果可为滨海盐沼湿地保护和碳循环研究提供基础支撑，对区域碳中和目标的实现具有潜在参考价值。 |

| Abstract: |
| To analyze the carbon density characteristics of coastal salt marshes and evaluate the current status of carbon density.An on-site survey was carried out in the typical coastal salt marshes in the Liaohe Estuary area of the Bohai Sea.According to the vegetation types,ecological characteristics,and topographic changes of salt marshes,27 sampling points were selected to determine the biomass and organic carbon content of vegetation and soil samples.The carbon densities of different types of soil and vegetation were calculated,and the carbon density status and changes of salt marshes were estimated.The results indicated that the carbon density in the study area followed the descending order of bare land,Suaeda salsa area,and Phragmites australis area,which showed the average carbon densities of 166.46,114.83,and 77.06 t/ha,respectively.Sea level rise caused by climate change greatly reduced the carbon sink of coastal wetlands.The findings provide basic support for wetland protection and carbon cycle research and have potential reference value for the achievement of regional carbon neutrality. |
