摘要
在新型城镇化建设过程中需要加强对历史文化遗产的保护利用,南浔古镇作为夏热冬冷地区建筑文化的典型代表,阐明其水岸空间微气候特性,可为我国历史文化古镇的环境营造和性能改善提供科学依据。本研究通过现场实测和问卷访谈相结合的方式,探究水岸空间环境参数的分布规律,计算生理等效温度(PET),分析人体热感觉与微气候参数的相关性,建立南浔古镇冬季水岸空间热舒适评价模型,得到热中性PET值为12.2℃以及舒适区间是8.9~16.5℃,确定了主观热感觉投票(TSV)与PET之间的量化关系,明确了冬季最舒适为微热状态(TSV=0.7),验证了水体流向、亲水距离、植被组合、遮阳方式和下垫面等因素对水岸微气候产生的具体影响;掌握了不同场地影响热感觉的关键环境参数,并提出相应改善对策。
In the process of new urbanization construction,it is imperative to strengthen the protection and utilization of historical and cultural heritage.As Nanxun Ancient Town is a typical representative of architectural culture in hot summer and cold winter regions,clarifying the microclimate characteristics of its waterfront space can provide a scientific basis for the environment construction and performance improvement of historical and cultural ancient towns in China.Through the combination of field measurement and questionnaire interviews,this study explored the distribution of environmental parameters in waterfront space,calculated Physiological Equivalent Temperature(PET),analyzed the correlation between human thermal sensation and microclimate parameters,and established the evaluation model of winter waterfront space thermal comfort in Nanxun Ancient Town.The results showed that the thermal neutral PET value was 12.2℃and the comfort range was 8.9~16.5℃.Then,the quantitative relationship between the subjective Thermal Sensation Vote(TSV)and PET was determined,and the mild thermal state(TSV=0.7)was the most comfortable state in winter.Finally,the specific effects of water direction,water accessible distance,vegetation combination,shading mode and underlying surface on waterfront microclimate were verified.In addition,the key environmental parameters affecting thermal sensation at different sites were mastered,and corresponding countermeasures were put forward.
