海洋碳汇分类方法框架探索与构建

Exploration and Construction of Methodological System for Ocean Carbon Sink Classification

海洋是地球上最大的碳汇,对于缓解全球气候变化发挥着关键作用。加快海洋碳汇分类研究,是切实提升对海洋碳汇分类科学认知、推动海洋生态保护修复、促进碳汇市场交易和实现“双碳”目标的重要举措。本研究从“发展-保护-碳汇”综合视角出发,系统梳理了目前海洋碳汇分类的现实困境,致力于构建一个适用于我国的多层次、多维度海洋碳汇分类框架。旨在针对中国特有的海洋生态系统,通过细化碳汇的形成属性、作用机制、空间分布、生态系统类型、碳库种类及物种差异等方面,深入解析海洋碳汇的组成与特点,以揭示海洋碳汇的形成机制、变化趋势和潜在潜力,为海洋碳汇的监测、评估和管理提供科学管理框架,为开展海洋碳汇分区分类提供实践指导。

The ocean is the largest carbon sink on Earth and plays a critical role in mitigating global climate change.Accelerating research on the classification of oceanic carbon sinks is a vital measure to enhance scientific understanding of oceanic carbon sink classification,promote the restoration of marine ecosystems,facilitate carbon sink market transactions,and achieve dual carbon goals.This study,starting from an integrated perspective of“development-protection-carbon sink”,systematically reviews the current challenges in the classification of oceanic carbon sinks,and is dedicated to constructing a multi-level,multi-dimensional framework for the classification of oceanic carbon sinks tailored to China’s unique marine ecosystems.It aims to provide an in-depth analysis of the composition and characteristics of oceanic carbon sinks,specific to China’s unique marine ecosystems,by refining aspects such as the formation properties,mechanisms of action,spatial distribution,types of ecosystems,categories of carbon stocks,and species differences.This endeavor seeks to reveal the formation mechanisms,trends,and potential of oceanic carbon sinks,thereby offering a scientific management framework for monitoring,assessing,and managing oceanic carbon sinks and providing practical guidance for the classification and zoning of oceanic carbon sinks.
