Study on the Correlation between Wind-Heat Environment and Spatial Form in the Streets of Huizhou Traditional Villages:A Case Study based on Hong Village in Yi County
摘要
Abstract
Streets constitute a critical skeletal system in the formation of settlements and serve as an essential linear space for the development of settlement structures.With progress in rural tourism economies,more attention is being paid to the wind-heat environment and the environmental comfort of street spaces in villages.Components of street spatial forms in Hong Village,Yi County,were analyzed and seven quantitative design indicators were determined:aspect ratio of streets,height difference,orientation,interface opening rate,gray space area ratio,water greening area ratio,and node area ratio.Meanwhile,microclimatic factors(air temperature,relative humidity,wind speed,and solar radiation)in streets were monitored on typical weather days in winter and summer.The human thermal comfort index of physiological equivalent temperature(PET)was calculated by the Ray Man software to construct a multi-linear regression model.Results indicate that:(1)in winter,PET of the study area has negative correlations with the aspect ratio,orientation,interface opening rate,gray space area ratio,and water greening area ratio,but it demonstrates positive correlations with height difference and node area ratio.In summer,PET has negative correlations with the aspect ratio,height difference,orientation,interface opening rate,and water greening area ratio,but it has positive correlations with the gray space area ratio and node area ratio.(2)The aspect ratio,height difference,orientation,gray space area ratio,and water greening area ratio significantly affect PET in winter.Specifically,aspect ratio affects PET the most(27.49％),followed by gray space area ratio(21.99％),water greening area ratio(18.16％),orientation trend(16.33％),and height difference(16.03％),successively.In summer,the aspect ratio and orientation significantly negatively affect PET.The aspect ratio(92.16％)influences PET markedly more than orientation(7.84％).(3)The diurnal variation of PET in each street demonstrates a stable trend of first rising and then decreasing in both winter and summer.(4)Optimal street spatial form in Hong Village is achieved within 4～6 for aspect ratio,1.5～2.5m for the height difference,30°～60° for orientation,0.1～0.3 for the interface opening rate,0.05～0.15 for the gray space area ratio,0.05～0.15 for the water greening area ratio,and 0.1～0.15 for the node area ratio.(5)It is suggested to appropriately lower building height,increase point green plants and vertical green plants without occupation of ground spaces,and other spatial form designs of streets,which help improve the environmental quality of streets.(6)When the street orientation aligns with the included angle of wind directions,an obvious"narrow pipe effect"will be formed,and a reasonable road network layout will consider local prevailing wind directions.Research results can provide theoretical support and design references to optimize the spatial forms of streets in Huizhou traditional villages and promote the development of rural settlement environments.关键词
