摘要
城市街道空间是城市重要的户外公共生活空间。由行道树和街谷构成的林荫街谷空间对改善街道空间微气候和调控冬夏两季热舒适环境起着重要作用。通过对西安2组城市"单拱"型林荫街谷空间进行冬季微气候实态测试,分析归纳林荫街谷冬季动态热环境的气温变化特征,将"相对热舒适"区域划分为"冷区"(不舒适区)、"暖区"(舒适区)、"日晒区"(愉悦区),并建立2种热环境动态变化模式,同时基于人体热健康"动态热适应"原理,提出冬季面向健康热环境的街道空间调控策略,对以西安为代表的建筑气候区划中的寒冷地区街道空间气候适应性设计提供了一定的参考价值。
Urban street space is an important outdoor public living space in the city,and the tree-lined street valley space composed of road trees and street valley plays an important role in improving the microclimate of street space and regulating the thermal comfort environment in winter and summer.Based on the real-state test and analysis of winter microclimate in two groups of cities in Xi’an,the dynamic change characteristics of"Single Arch"Tree-lined street valley space thermal environment were studied.The area of relative thermal comfort is divided into cold area(uncomfortable area),warm area(comfortable area),and sun area(pleasant area),and two dynamic modes of thermal environment are established.Based on the principle of"dynamic thermal adaptation"of human thermal health,this paper puts forward the street space regulation strategy for the healthy thermal environment in winter,which is of applied value to the design of the climate adaptability of the street space in the cold area in the"Building Climate Zone",represented by Xi’an.
