| 摘 要： | 开展城市建筑物方位、高度等建筑布局要素对局地热环境时空变化的影响研究，对于合理的城市规划布局具有重要理论意义与实践参考价值。采用ENVI-met 微气候模式，在南京江北新区顶山街道某区域微气候模拟的基础上，选择一个二类居住用地并设计不同的建筑布局要素作为规划场景，模拟分析了建筑物高度与建筑间距之比（H/W）、建筑布局变化对区域热环境的影响。结果表明:ENVI-met 能够以较高精度模拟2 m高度气温；H/W与建筑布局形式都会影响区域热环境，适当增加H/W可在一定程度上降低夏季气温，H/W为1.4时的热环境更为舒适，而不同建筑布局形式下的不同区域温度差异较大。

| Abstract: | Research on the influence of urban building layout, such as building location and height, on the regional thermal environment distribution is of great theoretical as well as practical significance for rational urban planning and layout. In this paper, based on simulating microclimate characteristics in a region of the Dingshan District in the Nanjing Jiangbei New Area by using the ENVI-met model and different building layout elements as the design scene in one residential district, the influence of the ratio of the building height to the distance between buildings (H/W), and the building layout on the regional thermal environment is simulated and discussed. The temporal changes in simulated air temperature at the height of 2 m are found to be consistent with field observations. H/W and the building layout affect the regional thermal environment. To some degree, increasing H/W can reduce the air temperature in the summer, with the most comfort when H/W is 1.4. Larger air temperature differences are observed within various locations for various building layout conditions. |
