Abstract

Previous studies have shown that tree arrangement provides effective regulation of the outdoor thermal environment and combats the urban heat island (UHI) effect. To further explore semi-outdoor thermal environment improvement using tree arrangement, we selected two common arbor species from Guangdong Province, namely, Lagerstroemia speciosa and Bombax ceiba. We discuss the influence of courtyard tree arrangements on the thermal environment of semi-outdoor spaces (courtyards and overhead spaces) of a teaching building in a hot-humid area. The ENVI-met model was used and verified with field measurements; the universal thermal climate index (UTCI) was used as an index to evaluate the thermal environment of semi-outdoor spaces. We found that (1) adjusting the distance between trees and buildings reduced the UTCI values by 0.4 (overhead spaces) and 0.8 ℃ (courtyards); and (2) when the distance between the arbor and the building is fixed, the UTCI values of arranging Lagerstroemia speciosa can be reduced by up to 0.5 (overhead spaces) and 1.0 ℃ (courtyards) compared to that of Bombax ceiba; this study provides practical suggestions for the layout of trees in semi-outdoor spaces of teaching buildings in the hot-humid areas of China.

树种和种植位置对半室外空间室外热舒适的影响

以往的研究表明，树木的布置可以有效调节室外热环境，对抗城市热岛效应。为了进一步探讨树木布置对半室外热环境的改善作用，我们选择了广东常见的两种乔木树种Lagerstroemia speciosa和Bombax ceiba。探讨了湿热地区某教学楼半室外空间(院落和架空)中院落树木布置对热环境的影响。采用了ENVI-met模型，并进行了现场实测验证;采用通用热气候指数(UTCI)作为评价半室外空间热环境的指标。结果表明:(1)调整树木与建筑物之间的距离，可使地面空间和庭院的UTCI值分别降低0.4℃和0.8℃;(2)在乔木与建筑距离一定的情况下，与木棉相比，布置紫薇的UTCI值可降低0.5℃(架空)和1.0℃(庭院);本研究为中国湿热地区教学建筑半室外空间的树木布局提供了实用建议。

期刊介绍： The Journal publishes original research papers, review articles and short communications on studies examining the interactions between living organisms and factors of the natural and artificial atmospheric environment. Living organisms extend from single cell organisms, to plants and animals, including humans. The atmospheric environment includes climate and weather, electromagnetic radiation, and chemical and biological pollutants. The journal embraces basic and applied research and practical aspects such as living conditions, agriculture, forestry, and health. The journal is published for the International Society of Biometeorology, and most membership categories include a subscription to the Journal.
