中国武漢市青山区を対象に、低影響開発（LID）の多目的最適化と多基準適性評価にライフサイクル炭素便益を統合する枠組みを構築した研究。透水性舗装とバイオレテンションセルを代表施策とし、異なる計画目標下での最適構成を導出。透水性舗装比率が高いほど流出抑制性能が向上し、全最適化案がライフサイクルで純炭素吸収源となり、LID面積拡大で最大−26.4Kt CO₂の削減効果を示した。
English
This study builds an integrated framework embedding life-cycle carbon benefits into LID multi-objective optimization and multi-criteria suitability assessment, applied in Wuhan's Qingshan District. Using permeable pavements and bioretention cells, it derives optimal configurations under varying planning objectives. Higher permeable-pavement shares improve runoff control; all optimized schemes are net carbon sinks, with total LID area expansion cutting up to −26.4 Kt CO₂ and bioretention share yielding non-linear carbon gains.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
雨水管理と炭素削減を同時評価する枠組みは、日本の都市計画・適応策におけるグリーンインフラ導入や自治体の脱炭素計画策定に示唆を与える。ただしSSBJや有報開示との直接接続は弱い。
In the global GX context
The framework links stormwater infrastructure with life-cycle carbon accounting, relevant to global green-infrastructure and adaptation planning under climate disclosure. It offers a methodological template for integrating carbon metrics into urban water investment decisions, though it does not engage TCFD/ISSB disclosure directly.

📄 Abstract（原文）
Study region The study area is located in Qingshan District, Wuhan, Hubei Province, China. Study focus Under the combined influences of climate change and rapid urbanization, urban pluvial flooding increasingly threatens infrastructure and public safety. Concurrently, accelerated urban development has intensified carbon-related environmental pressures. Low impact development (LID) emerges as an effective strategy for mitigating urbanization impacts through stormwater control and its carbon mitigation potential. However, existing LID suitability assessments for high-performance scheme design mainly focus on hydrological performance, with limited consideration of carbon processes. In this study, we develop an integrated framework that incorporates life-cycle carbon benefits into LID multi-objective optimization and multi-criteria suitability evaluation. The framework is applied in Wuhan, a national Sponge City pilot, using permeable pavements and bioretention cells as representative measures to derive optimal configurations under different planning objectives. New hydrological insights for the region The results indicate that schemes with higher proportions of permeable pavements achieve better runoff regulation performance. All optimized schemes act as net carbon sinks over the life cycle, and increasing total LID area significantly enhances carbon mitigation, with the reduction up to −26.4 Kt CO₂. Moreover, increasing the proportion of bioretention cells produces pronounced non-linear gains in net carbon reduction. The developed suitability assessment method can effectively balance multiple objectives under varying implementation priorities, contributing to flood management and low-carbon development in Sponge City construction.
