この研究は、成都・重慶都市集積地域を対象に、正味炭素排出量、経済貢献度、生態学的支持係数に基づく三次元フレームワークを開発し、炭素収支パターンを分析した。その結果、高排出コアと強炭素吸収周辺部のパターンが明らかになり、低炭素維持ゾーンが面積の45.15%を占めることが示された。人口密度や土地利用強度、政府介入が主要な駆動要因であり、これらの知見は地域の差別化された緩和策と国土空間計画に貢献する。

This study develops a three-dimensional framework based on net carbon emissions, economic contribution, and ecological support coefficients to analyze carbon balance patterns in the Chengdu-Chongqing urban agglomeration. Results show a high-emission core and strong carbon-sink periphery, with low-carbon maintenance zones covering 45.15% of the area. Population density, land-use intensity, and government intervention are key drivers, with interaction effects stronger than single-factor effects. These findings inform differentiated mitigation and territorial spatial planning.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
この研究のゾーニング手法は、日本の都市圏（東京・大阪など）における脱炭素型国土計画に応用可能であり、特にSSBJや自治体の温暖化対策計画との連携が期待される。ただし、中国の政策枠組みを前提としているため、日本の制度への適用には調整が必要。
In the global GX context
This paper offers a replicable three-dimensional framework for carbon balance zoning that can inform territorial spatial planning in rapidly urbanizing regions globally, aligning with IPCC guidelines and UNFCCC reporting.
👥 読者別の含意
🔬研究者:The three-dimensional framework and driver analysis provide a methodological template for carbon accounting studies in urban agglomerations.
🏢実務担当者:Urban planners can apply the zoning approach to identify priority areas for emission reduction and carbon sink enhancement.
🏛政策担当者:The differentiated governance zones offer a basis for targeted mitigation policies and spatial planning interventions.
📄 Abstract（原文）
Against China's "dual-carbon" backdrop, identifying carbon balance patterns and governance zones in rapidly urbanizing regions is central to territorial spatial optimization. Using the Chengdu-Chongqing Urban Agglomeration as a case, this study develops a three-dimensional framework based on net carbon emissions, economic contribution, and ecological support coefficients to link carbon accounting, driver diagnosis, and zoning governance. Results show that: (1) The region exhibits a "high-emission core-strong carbon-sink periphery" pattern, with emissions peaking at 1.42×10 8 t in 2010, rebounding to 1.28×10 8 t in 2020, and carbon sinks increasing by only 0.82%. (2) Low-carbon maintenance zones dominate, accounting for 45.15% of the area, whereas high-carbon optimization and carbon-intensity control zones cluster in the dual-core area and development corridor. (3) Population density, land-use intensity, and government intervention are key drivers, with interaction effects stronger than single-factor effects. These findings inform differentiated mitigation and territorial spatial planning in the region.
