摘要
目前城市热岛效应等小气候问题日益突出,作为对城市热岛效应影响较为显著的下垫面来说,有必要通过科学的监测来明确其缓解热岛效应的作用。本文以建立湿、热等小气候要素与城市街头绿地下垫面的关联特性为研究目的,以北京城市街头绿地为研究对象,以1~10hm~2为研究尺度。对砖、石、木、塑胶、花岗岩、草坪等灰垫面和绿垫面;以及相同材质,不同颜色灰垫面对相对湿度、地表温度及热应力指数等小气候要素进行了实测。分析测试数据,研究城市街头绿地灰垫面种类和颜色与小气候要素之间的量化关系。提出以调节改善小气候为导向的城市街头绿地设计的优化对策。
Currently urban heat island and other microclimate issues have become increasingly prominent,as the impact on the urban heat island effect is more significant underlying surface,which is necessary through scientific tests to confirm its ease heat island effect.In this paper,Correlation of hot and humid microclimate factors and Urban Green Street underlying surface for research purposes,In the streets of Beijing Urban Green Space for the study,In order to study the scale 1-10 h,do testing for the most common green street landscape underlying surface which is the six kinds of brick,stone,wood,grass;and the same material in different colors,related to microclimate elements such as relative humidity,LST and heat stress index.Analysis of the test data,study on the quantitative relationship between the urban green street underlying surface species,color,and microclimate factors.An optimization strategy for the design of urban street green space,which is based on the improvement of the microclimate,is put forward.
