摘要

海平面上升直接改变河口感潮沼泽的水文和盐度特征，是河口感潮沼泽面临的主要环境问题之一。总结了海平面上升对河口感潮沼泽碳动态影响的研究方法和实验平台，分别从海平面上升引发的盐水入侵和水淹增加2个方面综述海平面上升对河口感潮沼泽CH4和CO2排放通量、产生速率和土壤有机碳厌氧矿化途径等方面的影响及其机制。盐水入侵显著降低河口感潮淡水沼泽CH4产生速率和排放通量，导致土壤有机碳厌氧矿化途径从CH4产生为主向硫酸盐异化还原为主转变，然而盐水入侵对CO2排放通量的影响具有不确定性。水淹增加对河口感潮沼泽CH4和CO2排放通量影响的报道相对较少，已有研究表明CO2排放通量随着水淹高度增加而降低。最后提出海平面上升对河口感潮沼泽碳动态影响研究应加强的领域，以期为海平面上升对河口感潮沼泽含碳温室气体动态的影响研究提供参考。

Abstract

Sea-Level Rise (SLR) directly changes the hydrology and salinity of estuarine tidal wetlands and is one of the primary drivers of global change that significantly impacts ecosystem processes. Herein, various methodologies and experimental facilities (marsh organs, weirs, and flow-through mesocosms) for manipulating SLR are systematically reviewed. This study provides a comprehensive summary of the effects and mechanisms associated with SLR regarding the fluxes and production rates of CH4 and CO2, and the pathways and rates of soil organic carbon mineralization from the perspectives of SLR-saltwater intrusion and inundation increase. Saltwater intrusion due to SLR notably decreases CH4 production rates and fluxes. It induces a shift in the pathways of soil organic carbon mineralization, transitioning from CH4 production to microbial SO42- reduction in tidal freshwater marshes. The main mechanism reducing saltwater intrusion-induced CH4 flux is the increased presence of the electron acceptor SO42-, which hinders soil CH4 production. The impact of SLR through saltwater intrusion on CO2 emissions in tidal freshwater marshes exhibits distinct uncertainty. Owing to the inherent challenges in experimentally manipulating SLR in situ, few reports concerning the effects of SLR-related inundation on CH4 and CO2 fluxes and production rates exist. However, some studies have suggested that an increase in inundation height leads to a reduction in CO2 emissions. Additionally, this study consolidates information surrounding electron acceptors and microbial mechanisms associated with SLR that influence the pathways and rates of soil organic carbon mineralization in coastal tidal wetlands. Finally, this study outlines the specific domains that warrant further exploration in future research on the impact of SLR on the production and emission of carbon greenhouse gases in estuarine tidal marshes.

Key words： Sea level rise; Saltwater intrusion; Inundation increase; Carbon dynamics; Estuarine tidal marsh
