摘要

本研究采用以可持续性为重点的评估框架,对泰国曼谷大都市的城市热岛(UHI)脆弱性进行了评估,该框架包含三个脆弱性组成部分:暴露程度、敏感性和适应能力。在评估过程中,我们使用了特高气温易损性指标来确定特高气温易损性的范围和程度。此外,超高温影响指标还与可持续发展的三大支柱(社会公平、经济可行性和环境保护)相一致。结果表明,在暴露部分,与地表温度和不透水表面积相关的指标具有较高或非常高的特高压暴露指标得分。在敏感性部分,与建筑环境、绿地和水体相关的指标显示出较高至非常高的超高温影响敏感性指标得分。在适应能力部分,与政府政策和行动、多机构合作以及获得气候控制设备相关的指标需要采取纠正行动。大都市和行政区一级的特高温易损性指数确定了不同城市地区的特高温易损性程度和规模,高暴露指数和高敏感性指数以及低适应能力指数导致了特高温易损性高。从根本上说,这些研究结果有助于城市规划者和决策者制定有效的战略,以减轻特高温影响并提高城市的抗灾能力。

Assessment of urban heat Island vulnerability using sustainability-focused framework: A case study of Thailand's Bangkok Metropolis

This research assesses the urban heat island (UHI) vulnerability of Thailand's Bangkok metropolis using a sustainability-focused assessment framework which encompasses three vulnerability components: exposure, sensitivity, and adaptive capacity. In the assessment, the UHI vulnerability indicators are used to determine the extent and magnitude of UHI vulnerability. In addition, the UHI vulnerability indicators are aligned with the three pillars of sustainability: social equity, economic viability, and environmental protection. The results show that, under the exposure component, the indicators related to land surface temperature and impervious surface area have high to very high UHI exposure indicator scores. Under the sensitivity component, the indicators related to built environment, green spaces, and water bodies exhibit high to very high UHI sensitivity indicator scores. Under the adaptive capacity component, the indicators associated with government policy and action, multi-agency collaboration, and access to climate control appliances require corrective action. The metropolis- and administrative district-level UHI vulnerability indexes identify the extent and magnitude of UHI vulnerability of different urban areas, with high exposure and high sensitivity indexes and low adaptive capacity indexes contributing to high UHI vulnerability. Essentially, the findings enable urban planners and policymakers to formulate effective strategies to mitigate the impacts of UHI and enhance the city's resilience.
