杭州夏季户外风景园林空间小气候测定研究

Study on Microclimate Measurement of Hangzhou Outdoor Landscape Space in Summer

全球气候剧变对人类城市生存环境产生了深刻影响。为应对杭州城市空间小气候变化,改善夏季人体的户外热舒适度,文章以杭州城区某户外风景园林空间为研究基地,实地测量了该场地夏季小气候热、温、湿、风各要素的量化数据,并根据数据统计结果计算得出衡量人体热感受的PET(physiological equivalent temperature)指标,最后针对实测场地,初步提出小气候适应性设计的改造重点。文章对杭州夏季小气候的肌理和改善进行了探讨,对该地区户外小气候研究具有一定的借鉴意义。

The global climate change has profoundly affected the living environment of human cities.In order to cope with the microclimate change of Hangzhou’s urban space and improve the outdoor thermal comfort in summer,this article takes an outdoor landscape space in Hangzhou urban area as the research base,and measured the quantitative data of the summer microclimate heat,temperature,humidity,and wind factors on the site.Based on the statistical results of the data,the PET(Physiological Equivalent Temperature)index that measures human thermal sensation is calculated.At the end of the article,according to the measured site,the key points of the microclimate adaptive design reformation were proposed.This article discussed the texture and improvement of Hangzhou microclimate in summer,which has certain reference significance for the outdoor microclimate research in similar area.
