摘要
为探讨影响广州地区村落巷道夏季室外热舒适的关键形态参数,以及形态参数对热舒适的影响规律,对广州常见的“梳式”布局村落黄屋村进行了实地调研、热环境实测、巷道形态参数模型的微气候模拟及热舒适指标和形态要素的关联分析。得出以下主要结论:1)通过归一互化信息(NMI)的计算,确定了天空角系数(SVF)是对村落巷道热舒适贡献度最大的形态参数指标;2)村落巷道SVF和高宽比(H/W)之间在H/W小于2时存在明显的负相关;3)普通巷道中的生理等效温度(PET)会随着SVF的增加而降低,但东西(E-W)朝向巷道降低速率最慢;4)确定了遮阳设施对巷道热舒适的提升能力,并指出了不同宽度的遮阳设施对村落巷道PET的具体影响,并给出了遮阳设施的最佳宽度为1 m。以上结论可为广州地区村落规划设计提供必要的导引。
To examine the morphological parameters influencing outdoor thermal comfort during the summer in the alleys of villages in Guangzhou,as well as to assess the influence of these parameters on thermal comfort,the research involved conducting field studies in Huangwu village,a representative example of the“comb-lie”layout commonly found in Guangzhou,thermal environment measurements,and microclimate simulations of the morphological parameter model of the alleys.The analysis of the correlation between thermal comfort indicators and morphological elements yielded the following principal conclusions:1)The Sky View Factor(SVF)emerged as the most influential morphological parameter for enhancing thermal comfort in village alleys,as determined by the Normalized Mutual Information(NMI)method;2)A significant negative correlation was observed between the SVF and the height-to-width ratio(H/W)of the village alley when the H/W was less than 2;3)The Physiologically Equivalent Temperature(PET)in typical alleys decreased with an increase in the SVF,with the slowest rate of decrease occurring in east-west(E-W)oriented alleys;4)The ability of shading facilities to enhance thermal comfort in alleys was determined,and the specific effect of different widths of shading facilities on PET in village alleys was noted.It was determined that the optimal width for shading facilities is 1 meter.Based on the above conclusions,necessary guidance can be provided for the planning and design of villages in Guangzhou.
