摘要
校园是师生活动的主要场所,为研究不同下垫面对人体舒适度的影响,在广东海洋大学湖光校区选取三种不同性质的下垫面,开展夏季小气候观测与数值模拟。利用Origin、SPSS和ENVI-met软件进行数据处理。研究结果表明:(1)在校园现有的绿化和建筑布局下,风对小气候的影响较大;夏季无降水时,通风条件差的少遮荫草地温度高、湿度低,舒适感较差。(2)合理密植高大的绿化林,可以有效降低夏季地面温度。(3)ENVI-met模型在热带稳定变化的天气条件下模拟效果较好,能在一定程度上反映校园内区域小气候特征,其模拟结果可为校园基础设施建设的优化和师生出行提供科学依据。
Campus is the main place for the activities of teachers and students.In order to study the influence of different underlying surfaces on human comfort,three types of underlying surfaces with different properties are selected in Huguang campus of Guangdong Ocean University to carry out the observation and numerical simulation of microclimate in summer.Origin,SPSS,and ENVI-met softwares are used for data processing.The results are shown as follows.(1)Under the existing greening and building layout of the campus,wind has a great impact on the microclimate.When there is no precipitation in summer,the less shaded grassland with poor ventilation condition has higher temperature,lower humidity,and less comfort.(2)Reasonable dense planting of tall green forest can effectively reduce the ground temperature in summer.(3)ENVI-met model has a good simulation effect under stable tropical weather conditions,which can reflect the regional microclimate characteristics of the campus to a certain extent.The simulation results can provide scientific basis for the optimization of campus infrastructure construction and the travels of teachers and students.
