| 摘 要： | 为量化分析下垫面对局地热环境的影响,采用多用途建筑区域热气候评价模型,以深圳国际低碳城核心启动区为对象,讨论下垫面构成对热岛强度及热舒适性的影响.研究表明:最大局地热岛强度体现最热极端情况的气候差异,平均局地热岛强度反映全天气温的平均差异;夜间平均局地热岛强度高于白天;自然下垫面中,增大水体和树木的覆盖率起到的降温效果更好,而适当增加草地的覆盖率能更有效地提高室外环境舒适度. |

| Abstract: | To analyze the effect of underlying surfaces on local thermal climate, this paper took the international low-carbon city of Shenzhen as an example, and the effects of different underlying surfaces on the urban heat island (UHI) and outdoor thermal comfort were discussed by using multipurpose regional thermal climate prediction model. The results showed that the maximum urban heat island intensity(UHII) reflected the temperature difference between urban and suburban of the hottest cases while the average local UHII reflected the average difference of the whole day. And the average local UHII of night was higher than the average local UHII of daytime. Besides, the cooling effects of water and trees were better compared with other natural underlying surfaces, while appropriate increase of grass coverage could more effectively improve the outdoor thermal comfort. |
