Abstract

Although previous studies have confirmed the urban park cooling effects (UPCE), it is unclear how their cooling services are connected to and equitably distributed among users. In response to the "urban cooling action" in cities across China, this study links the cooling intensity and multimodal Ga2SFCA (MM-Ga2SFCA) to develop a methodology framework to assess the community-level urban park cooling service performance (UPCSP) per capita. Taking the highly urbanized Nanjing central districts (NCDs) as an example, the main conclusions are: (1) The average cooling magnitude of 200 parks on August 12, 2022, September 18, 2021 and October 4, 2021 was 2.22 °C; the average maximum cooling scale (MCS), maximum cooling efficiency (MCE), cumulative cooling intensity (CCI) and cumulative cooling gradient (CCG) were 41.29 ha, 2.99 times, 89.41 °C*m² and 0.70 °C, respectively. (2) The average comprehensive service performance of 545 communities within 5, 10, and 15 min were 117.97 °C*m², 212.04 °C*m², and 264.83 °C*m², respectively. (3) The spatial differences of UPCSP were mainly affected by the spatial layout of urban parks and their internal and external physical environments. These findings can provide useful implications for improving and balancing the UPCSP among communities.

响应 "城市降温行动"：中国南京社区级城市公园降温服务绩效评估与可视化

尽管之前的研究已经证实了城市公园的降温效应（UPCE），但其降温服务如何与用户联系并在用户之间公平分配尚不清楚。针对中国城市中的 "城市降温行动"，本研究将降温强度和多模式Ga2SFCA（MM-Ga2SFCA）联系起来，建立了一个评估社区级城市公园人均降温服务绩效（UPCSP）的方法框架。以高度城市化的南京市中心城区（NCDs）为例，主要结论如下(1）2022 年 8 月 12 日、2021 年 9 月 18 日和 2021 年 10 月 4 日，200 个公园的平均降温幅度为 2.22℃；平均最大降温尺度（MCS）、最大降温效率（MCE）、累积降温强度（CCI）和累积降温梯度（CCG）分别为 41.29 公顷、2.99 倍、89.41℃*m2 和 0.70℃。(2）545 个社区在 5 分钟、10 分钟和 15 分钟内的平均综合服务性能分别为 117.97℃*m2、212.04℃*m2 和 264.83℃*m2。(3) UPCSP 的空间差异主要受城市公园的空间布局及其内外部自然环境的影响。这些发现为改善和平衡社区间的 UPCSP 提供了有益的启示。

The journal welcomes cross-cutting, multi-disciplinary research in various areas, including: 1. Smart cities and resilient environments; 2. Alternative/clean energy sources, energy distribution, distributed energy generation, and energy demand reduction/management; 3. Monitoring and improving air quality in built environment and cities (e.g., healthy built environment and air quality management); 4. Energy efficient, low/zero carbon, and green buildings/communities; 5. Climate change mitigation and adaptation in urban environments; 6. Green infrastructure and BMPs; 7. Environmental Footprint accounting and management; 8. Urban agriculture and forestry; 9. ICT, smart grid and intelligent infrastructure; 10. Urban design/planning, regulations, legislation, certification, economics, and policy; 11. Social aspects, impacts and resiliency of cities; 12. Behavior monitoring, analysis and change within urban communities; 13. Health monitoring and improvement; 14. Nexus issues related to sustainable cities and societies; 15. Smart city governance; 16. Decision Support Systems for trade-off and uncertainty analysis for improved management of cities and society; 17. Big data, machine learning, and artificial intelligence applications and case studies; 18. Critical infrastructure protection, including security, privacy, forensics, and reliability issues of cyber-physical systems. 19. Water footprint reduction and urban water distribution, harvesting, treatment, reuse and management; 20. Waste reduction and recycling; 21. Wastewater collection, treatment and recycling; 22.
