【摘要】 社区绿地是居民活动的主要场所,场地微气候特征对人群使用率和活跃度有较大影响。严寒城市恶劣气候条件限制社区绿地中的户外活动,因此营造舒适微气候,对延长秋季寒冷天气下人群活动使用时间具有重要意义。本文选取严寒城市典型社区绿地作为研究对象,通过移动测量方法获取场地测试点的温湿度和风速数据,对其进行定量分析,进一步解析场地的微气候特征。结果表明:社区绿地的温度在上午和中午时段总体高于下午和傍晚时段,湿度变化与温度变化呈明显负相关;场地的总体布局、下垫面差异性(植物和硬质铺装)和周边高层建筑都是影响场地微气候的重要因素;社区绿地不同空间区域的微气候影响因素存在差异,需要根据空间特点进行相关设计。更多还原

【Abstract】 Community green space is the main place for residents’ activities,and the microclimate characteristics of the site have a greater impact on population utilization and activity.The severe climatic conditions in severe cold cities restrict outdoor activities in community green spaces,so it is of great significance to create a comfortable microclimate and extend the use of crowd activities in cold autumn weather.This paper selects the typical community green space in a severe cold city as the research object,and obtains the temperature,humidity and wind speed data of the test points of the site through the mobile measurement method,carries out a quantitative analysis on it,and further analyzes the microclimate characteristics of the site.The results show that the temperature of the community green space is generally higher in the morning and noon than in the afternoon and evening,and the humidity change is obviously negatively correlated with the temperature change;the overall layout of the site,the difference of the underlying surface(plants and hard paving) and the surrounding high-rise buildings are all important factors affecting the microclimate of the site;the microclimate influencing factors of different spatial areas of community green space are different,and relevant design needs to be carried out according to the spatial characteristics.更多还原
