基于ENVI-met的历史文化街道空间形态对夏季热舒适性影响研究
Study on impact of historical and cultural street spatial patterns on summer thermal comfort based on ENVI-met:A case study of Sanhe Ancient Town district in Hefei
摘要
Abstract
Under the combined effects of climate change and urbanization,the urban heat island effect is increasingly intensifying.Historical and cultural streets are important urban public spaces,and their thermal comfort directly affects residents'quality of life.Taking Sanhe Ancient Town,a famous historical and cultural district in Hefei,as the study object,this research uses a combination of on-site measurements and ENVI-met numerical simulations.Based on an orthogonal experimental design,16 street spatial form simulation schemes were constructed to systematically explore the influence patterns of street orientation,cross-sectional form,and greenery layout on summer Physiologically Equivalent Temperature(PET).The study found that ENVI-met can effectively simulate the thermal comfort of historical and cultural street spaces,with root mean square errors of temperature and humidity ranging from 0.85 to 3.08 and mean absolute percentage errors of 1.91%to 4.55%,all within allowable error ranges.North-south oriented streets have the best thermal comfort,followed by northeast-southwest and northwest-southeast orientations,with east-west orientations being the worst.Complex street cross-sectional forms are more conducive to improving street thermal environments.Appropriately increasing street trees can improve the thermal environment,with the optimal arrangement being symmetrical planting on both sides.The influence of street spatial form elements on thermal comfort is ranked as follows:street orientation>street cross-sectional form>greenery layout.Air temperature is significantly positively correlated with outdoor thermal comfort,while relative humidity is significantly negatively correlated with outdoor thermal comfort.关键词
