📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

中国の黒土地域に焦点を当てていますが、生態系サービスの相互作用を分析する手法は、日本の農地や森林の炭素吸収源管理にも応用可能です。特に、土壌保全と生息地質の相乗効果の重要性は、日本の農業政策やGX実践に示唆を与えます。

In the global GX context

While focused on China's black soils, this paper's framework for analyzing ecosystem service synergies to enhance carbon sinks is globally relevant. It provides a methodological approach that can inform land management and carbon sequestration strategies in other regions, including Japan.

摘要 增强陆地生态系统碳汇是减缓气候变化和推进可持续发展的重要策略。本研究以中国东北地区为案例，构建了一个整合生态系统服务在时间、空间和功能维度上相互作用的综合框架，以识别增强碳汇的路径。我们采用生态系统服务与权衡综合评估（InVEST）模型、时空差异比较方法、地理探测器以及多尺度地理加权回归（MGWR）模型，识别与碳储存（CS）最相关的生态系统服务（ESs）并分析其相互作用。通过比较2000年至2020年间单一生态系统服务的独立效应与多种生态系统服务对CS的交互效应，我们提出了增强碳汇和改善空间可持续性的策略。结果表明，生态系统服务对CS的交互效应强于其独立效应，其中土壤保持（SR）与生境质量（HQ）之间的效应系数最大（0.66），其次是粮食生产（FP）与HQ（0.63）。减少SR–HQ和FP–HQ之间的权衡并增强其协同作用，被确定为增加碳汇的关键路径。这些发现对于黑龙江省和内蒙古自治区黑土资源管理和农林系统优化尤为重要。本研究强调了放大生态系统服务间反馈以改善CS的重要性，并提出了针对黑土保护与恢复的具体措施，从而为可持续生态系统管理和气候变化减缓提供了科学基础和实际指导。

📄 Abstract（原文）

ABSTRACT Enhancing the terrestrial ecosystem carbon sink represents a critical strategy for mitigating climate change and advancing sustainable development. In this study, we developed a comprehensive framework that integrated ecosystem service interactions across temporal, spatial, and functional dimensions to identify pathways for enhancing carbon sinks, using Northeast China as a case study. We employed the Integrated Valuation of Ecosystem Services and Trade‐offs (InVEST) model, spatiotemporal difference comparison methods, Geodetector, and the Multiscale Geographically Weighted Regression (MGWR) model to identify the most relevant ESs for carbon storage (CS) and to analyze their interactions. By comparing the independent effects of single ecosystem services and the interaction effects of multiple ecosystem services on CS from 2000 to 2020, we proposed strategies for enhancing carbon sinks and improving spatial sustainability. The results showed that the interaction effects of ESs on CS were stronger than their independent effects, with the largest effect coefficients observed between soil retention (SR) and habitat quality (HQ) (0.66), followed by food production (FP) and HQ (0.63). Reducing trade‐offs and enhancing synergies between SR–HQ and FP–HQ were identified as key pathways to increase carbon sinks. These findings are especially important for managing black soil resources and optimizing agroforestry systems in Heilongjiang and the Inner Mongolia Autonomous Region. This study highlighted the importance of amplifying feedback among ESs to improve CS and proposed targeted measures for the protection and restoration of black soils, thereby providing a scientific foundation and practical guidance for sustainable ecosystem management and climate change mitigation.
