摘要
为探究夏热冬暖地区绿化生长对夏季校园步行空间热舒适度的影响,以福耀科技大学为案例,利用无人机红外摄影技术采集夏季校园步行空间的温度数据,并用于微气候模型的校准,通过数值模拟探究绿化生长的多种情景对夏季校园步行空间热舒适度的改善效果。研究结果表明:水体和绿化树木对室外热舒适度有明显改善,相较于其他区域,生理等效温度(PET).可减少2~3℃;绿化生长情景的模型仿真则说明绿地面积增大对热舒适度的改善有限,PET值可降低08~1℃,树冠面积增大对热舒适度有明显改善,PET数值减少了约2℃。为夏热冬暖地区夏季校园步行空间的绿化景观设计和热舒适度改善提供理论依据和实践参考。
To investigate the impact of vegetation growth on thermal comfort within summer pedestrian spaces in regions experiencing hot summer and warm winter area,Fuyao University of Science and Technology was selected as a case study.Unmanned aerial vehicle(UAV)infrared imaging technology was employed to collect temperature data across campus pedestrian areas during summer months.This data was utilised to calibrate a microclimate model,with numerical simulations subsequently conducted to examine how various vegetation growth scenarios enhance summer comfort within these spaces.Findings indicate that water bodies and green trees significantly enhance outdoor thermal comfort,reducing the physiologically equivalent temperature(PET)by 2~3℃compared to other areas.Model simulations of greenery growth scenarios reveal that increasing green space area yields limited thermal comfort improvements,lowering PET by 0.8~1℃.Conversely,expanding canopy coverage markedly enhances thermal comfort,reducing PET by approximately 2℃.This provides theoretical foundations and practical guidance for landscaping design and thermal comfort enhancement in summer pedestrian spaces within campuses located in areas characterised by hot summers and warm winters.
