摘要: 潮滩在提升自然生态系统碳储量和应对气候变化方面发挥着重要作用,是重要的蓝碳生态系统。潮滩沉积物中储存的有机碳是其碳汇功能的关键组成部分,但易受地形特征和沉积环境等生境要素的影响。为探究区域尺度下潮滩沉积物碳储量的空间分布格局及其主要调控因子,本研究选取舟山群岛6个典型岛屿为研究区域,系统分析了沉积物有机碳储量的空间分布特征,并基于绝对主成分得分-多元线性回归模型(APCS-MLR)定量解析沉积物理化因子对碳储能力的影响。结果表明:各采样点间沉积物碳储量存在明显的空间异质性。其中,碳储量最高值位于岱山岛(68.96 Mg C·hm-2),最低值位于六横岛(50.96 Mg C·hm-2)。在垂直分层上,大多数采样点表层(0~30 cm)、中层(30~60 cm)和底层(>60 cm)间有机碳储量差异不显著。采用APCS-MLR模型共提取出3个主成分,粒径结构、沉积状态和盐碱特征分别以37.0%、29.0%、20.0%的贡献率决定了舟山群岛潮滩沉积物的碳储能力。线性回归结果显示,粒径结构及沉积深度与碳储量呈极显著相关,而沉积状态与盐碱特征与碳储量的相关性不显著。本研究有助于加深对潮滩沉积物碳储机制的理解,并为区域蓝碳估算与海岸带碳汇管理提供科学依据与决策支持。

Abstract: Tidal flats, a type of blue carbon ecosystems, play a crucial role in enhancing carbon storage capacity of natural ecosystems and addressing climate change. The organic carbon stored in tidal flat sediments is a key component of their carbon sequestration function but is dependent on habitat factors such as topographic features and depositional environments. To investigate the spatial variations of carbon storage in tidal flat sediments and their primary regulating factors at the regional scale, we selected six typical islands in the Zhoushan Archipelago as research areas, systematically analyzed the spatial distribution characteristics of sedimentary organic carbon storage and quantified the impact of sediment physicochemical factors on carbon storage capacity using the Absolute Principal Component Score-Multiple Linear Regression (APCS-MLR) model. The results showed that there was significant spatial heterogeneity in sedimentary carbon storage among sampling sites, with the highest carbon storage value being recorded on Daishan Island (68.96 Mg C·hm-2) and the lowest on Liuheng Island (50.96 Mg C·hm-2). Most sampling sites showed no significant differences in organic carbon storage between the surface layer (0-30 cm), intermediate layer (30-60 cm), and bottom layer (>60 cm). The APCS-MLR model identified three principal components, with particle size structure, sedimentary state, and salinity-alkalinity characteristics contributing 37.0%, 29.0%, and 20.0% to the carbon storage capacity of tidal flat sediments in the Zhoushan Archipelago, respectively. Particle size structure and sedimentary depth exhibited significant correlations with carbon storage, while there was no relationship between sedimentary state and salinity-alkalinity characteristics and carbon storage. This study would enhance understanding of carbon storage mechanisms in tidal flat sediments and provide scientific support and decision-making for regional blue carbon estimation and coastal carbon sink management.
