我国湿热地区夏季空气温度和湿度相对较高,太阳辐射强烈,在学生相对集中且户外活动较多的大学校园中,此种气候条件可能会造成学生的身体不适甚至中暑。因此,在校园规划中应考虑景观设计对热环境的影响。本文通过对华南理工大学东湖周围的热环境变量进行测试,包括空气温度、湿度、风速和辐射热以及综合热环境指标——湿球黑球温度,获得了水体、乔木、草地和硬地等设计方法对热环境的影响程度。
In hot and humid areas of China,air temperature and relative humidity were relatively high in summer,as well as the solar radiation.In the university campus,students are concentrated and have more outdoor activities.Hot and humid weather conditions may cause students uncomfortable and even heat stroke.Therefore,the influences of landscape design on thermal environment should be taken into account in the process of campus planning.In this paper,the field measurements of outdoor air temperature,relative humidity,wind velocity,heat radiation and wet bulb globe temperature were carried out around the Dong Lake in South China University of Technology in typical summer days.The impacts of design methods of water,tree,grass and floor on thermal environment were analyzed.
