摘要/Abstract

摘要：

红树林作为重要的海洋蓝碳生态系统, 其沉积物碳含量具有显著的时空变异性, 这给其碳储量精准评估带来重要挑战。本研究选择南流江河口桐花树潮滩作为研究对象, 采集表层1~5cm厚的沉积物样品74个, 以系统分析不同植被覆盖区表层沉积物碳含量及其空间分布特征。结果表明: (1)桐花树潮滩沉积物碳含量存在显著空间分异: 基于林缘距离梯度分析显示, 碳含量自陆向海依次为林内区域(1.01±0.17)%>近林区域(0.58±0.16)%>远林区域(0.52±0.19)%; 同时, 不同生物地貌单元间碳含量差异显著, 表现为茂密林区(0.99±0.19)%>幼苗区(0.68±0.23)%>裸滩区(0.49±0.12)%, 分布格局与地上植被植株高度耦合; (2)桐花树潮滩沉积物碳含量主要受沉积物细颗粒物质、植被群落结构特征以及有机质输入情况等关键环境因子调控; (3)区域不同碳输入的差异是引起红树林潮滩碳含量空间分异的基础, 裸滩区以水体携带的碳通过悬沙落淤产生的物理沉积为主, 林区则受细颗粒截留、落叶凋零产生的有机质输入和土壤氧化还原环境共同影响。林外潮滩因红树林聚集生长效应和伴生植被作用可形成局部碳富集。研究结果可为红树林生态修复和蓝碳储存提供部分理论支撑, 为海岸带碳汇评估建立科学基础。

Abstract:

Mangroves, as pivotal blue carbon ecosystems in marine environments, demonstrate significant spatiotemporal variability in sediment carbon content, presenting considerable challenges for precise carbon stock quantification. This study systematically examined surface sediment carbon characteristics across different vegetation zones in the Aegiceras corniculatum-dominated tidal flats of the Nanliu River estuary to elucidate its spatial distribution patterns and accumulation mechanisms. The results reveal: (1) a pronounced spatial heterogeneity in carbon content, exhibiting a distinct landward-to-seaward decreasing gradient: inner forest (1.01±0.17)% > near-forest edge (0.58±0.16)% > outer flat (0.52±0.19)%, with significant variations among biogeomorphological units: dense forest (0.99±0.19)% > seedling area (0.68±0.23)% > bare flat (0.49±0.12)%, showing strong coupling with aboveground vegetation structure; (2) carbon content was primarily regulated by fine particles (clay/silt), vegetation community traits, and organic matter input; (3) spatial differentiation primarily stems from distinct carbon input pathways—bare flats dominated by physical sedimentation of suspended particulate carbon, while forested areas are regulated through synergistic mechanisms including fine particle retention, organic matter input from litterfall, and soil redox conditions. Notably, mangrove aggregation effects and associated vegetation facilitate localized carbon enrichment in outer tidal flats. These findings provide theoretical foundations for mangrove restoration and blue carbon storage strategies while establishing a scientific basis for coastal carbon sink assessments.
