本研究は広東省の主要都市において、街路樹、ポケットパーク、緑の屋根、緑の回廊などの自然に基づく解決策（NbS）が粒子状物質濃度と屋外温熱快適性に与える影響を調査した。固定・移動観測と都市形態マッピングを組み合わせた結果、適切に設計されたNbSは粒子状物質濃度を最大3分の1削減し、平均放射温度を最大2℃低下させることが示された。特に日陰と換気を組み合わせた緑の回廊で最大の効果が得られた。
English
This study examines how urban nature-based solutions (street trees, pocket parks, green roofs, green corridors) influence particulate matter concentrations and outdoor thermal comfort in major cities of Guangdong Province using combined measurements. Results show well-designed NbS can reduce daytime PM by up to one-third and lower mean radiant temperature by up to 2°C, with largest benefits in connected green corridors.

📄 Abstract（原文）
Rapid urbanization in warm and humid coastal regions has intensified exposure to particulate matter and outdoor heat stress, with significant implications for public health and energy demand. This article examines how urban nature-based solutions, including street trees, pocket parks, green roofs and integrated green corridors, influence particulate matter concentrations and outdoor thermal comfort in major cities of Guangdong Province. The study combines multi-year measurements from fixed and mobile monitoring stations with detailed urban morphology mapping and microclimate observations in representative street canyons, residential blocks and mixed-use districts. Thermal comfort is characterized using established human biometeorological indices, and particulate matter is measured at pedestrian height along paired nature-based solution and reference transects. Results indicate that well-designed nature-based solutions reduce daytime particulate matter concentrations by up to one third and lower mean radiant temperature by up to two degrees Celsius, with the largest benefits occurring in connected green corridors that combine shading and ventilation.
