中文摘要 【目的】为优化城市热环境与人居品质提供新视角。【方法】以武汉市江岸区滨水地段为例,结合街景数据与遥感气候数据,利用深度学习与ENVI-met模拟计算绿视率和生理等效温度(PET),分析其时空特征,探讨绿视率对热舒适度的影响。【结果】1)武汉市江岸区滨水地段内,绿视率受区域特征影响呈现分布差异;2)7∶00—15∶00,不同城市空间热舒适度(PET)变化速率不同,历史街区内部>街道区域>滨水公园区;3)绿视率与PET的负相关性随时间变化显著,早晨至中午逐渐增强,中午12∶00达到峰值后减弱;4)绿视率对PET的影响存在边际递减效应,绿视率在43.9%~47.3%时对PET的降低作用最显著(P＜0.05),超过此范围后改善效果减弱;5)绿视率对热环境稳定性的影响显著,高绿视率显著减小了PET的日变化幅度,表现为更稳定的热环境和更小的日温差?！窘崧邸砍鞘锌占淅嘈拖灾跋烊然肪扯卣?绿视率与PET呈负相关关系,其调控效应在日间辐射峰值时段(12∶00前后)最强且存在边际递减规律;合理配置绿视率是提升热舒适度的关键。未来需进一步探究多气候条件下绿视率与植被类型、配置方式的关联机制。

英文摘要 【Objective】The study is to provide a new perspective for optimizing the urban thermal environment and residential quality.【Method】 The waterfront sections of Jiang'an District in Wuhan are taken as a case study to calculate green view index (GVI) and physiologically equivalent temperature (PET) by integrating street-view imagery and remote sensing climate data with deep learning and ENVI-met simulations to examine their spatiotemporal characteristics and discuss the GVI's impact on thermal comfort.【Result】1) The distribution of GVI in the waterfront sections of Jiang'an District varies due to regional characteristics; 2) At 7∶00-15∶00, the PET presents varied rates across urban spaces of different kinds, i.e., historical district interiors > street areas > waterfront parks; 3) The significant negative correlation between GVI and PET strengthens from morning to noon, peaking at 12∶00 before weakening; 4) GVI has a diminishing marginal effect on PET. The GVI, when in the range of 43.9%-47.3%, has the most substantial subduing effect on PET, and the effect will reduce beyond the scope; and 5) GVI significantly enhances thermal environment stability. High GVI reduces PET's diurnal variation, leading to a more stable thermal environment with smaller temperature fluctuations. This not only improves thermal comfort, but also increases urban climate stability.【Conclusion】Urban spatial typology shapes thermal dynamics, with GVI negatively correlated with PET. Its cooling effect peaks around 12∶00 and follows a marginal diminishing pattern. The optimal GVI configuration is the key to improving thermal comfort. Future studies should explore GVI's interactions with vegetation types and spatial configurations under varying climates.
