中国城市街道的热舒适研究框架:地域差异、指标阈值和影响因素

Research Framework for Thermal Comfort of Urban Street in China:Geographical Differences,Indicator Thresholds and Influencing Factors

全球气候变化形势严峻,街道成为改善城市气候环境不可缺少的要素,街道的热舒适性品质对人群健康和城市建设发挥着重要的作用。以中国城市街道热舒适性为对象,基于中国知网和Web of Science的检索数据源,通过文献回溯概述相关研究的热点主题、重点方向、研究内涵和研究方法,分析地域影响下的热舒适指标阈值差异。基于中国建筑气候区划,进一步探讨影响街道热舒适的微气候因素、个体因素和空间因素,尝试表述中国城市街道热舒适的研究框架,提出建构中国本土的街道热舒适研究体系与评价体系,聚焦空间环境热舒适的关键科学问题,以及促进街道热舒适研究成果向设计实践转化,对积极探索城市宜居环境建设的规划设计具有现实意义。

The global climate change situation is complex,and streets are an indispensable means of improving the urban climate,with the thermal comfort qualities of streets playing a vital role in public health and the construction of cities.The research focuses on the thermal comfort of urban streets in China,based on the literature sources from China National Knowledge Infrastructure and the Web of Science.The literature review provides an overview of the relevant studies’hot topics,key directions,research content,and methods.It analyses the differences in thermal comfort indicator thresholds under geographical influence.Based on the architectural climate zoning of China,the article further explores the microclimatic,individual,and spatial factors that influence thermal comfort in streets in an attempt to formulate a research framework for thermal comfort in Chinese urban streets.In this paper,we propose the construction of a local Chinese street thermal comfort research system and evaluation system,focusing on the critical scientific issues of spatial environmental thermal comfort,thereby promoting the transformation of street thermal comfort research results into design practice,which is of practical significance for actively exploring the planning and design of urban livable environment construction.
