中文摘要:
      城市不同下垫面与建筑物空间形态对近地表气温等微气候要素产生了重要影响。开展城市气温时空变化模拟与影响因素分析,对于城市热环境评价与城市规划具有重要意义。论文基于高空间分辨率Geoeye-1立体影像,在建筑物高度、下垫面覆盖类型信息提取的基础上,选择南京一中、光华东街、玄武湖、头陀岭4个区域,采用ENVI-met微气候模式,以城市基本气象站南京站的实时气象数据作为背景气象场,模拟不同区域近地表气温的时空分布特征,并利用区域自动气象站观测数据进行精度检验。结果表明:在时间变化上,ENVI-met模拟气温与实测值之间吻合程度较高;在空间分布上,南京一中与光华东街区域气温时空分布规律总体相似,但城市空间形态的差异使得局部区域气温变化不同,玄武湖区域气温由陆地中心向外围呈递减趋势,而头陀岭地形复杂多变,白天气温变化剧烈,夜间空间变化较小。
Abstract:
      Different types of underlying land surface cover and various urban spatial morphologies have an important effect on micro-climate parameters. Simulating the spatio-temporal distribution of urban air temperature and analyzing its influencing factors are of great significance to evaluate urban thermal environment and urban planning. In this paper, ENVI-met micro-climate model is used to simulate the spatio-temporal distribution characteristics of surface air temperature in some areas of Nanjing, including Nanjing Middle School I, Eastern Guanghua Street, Xuanwu Lake, and Toutuoling. The distribution of buildings and their heights as well as the underlying land cover information are extracted from the high spatial resolution Geoeye-1 stereoscopic images. The simulated results based on ENVI-met micro-climate model are validated using the measurements collected at Nanjing national meteorological station. It is found that the temporal changes in simulated surface air temperature are consistent with observations. For the spatial distribution characteristics, the surface air temperature distribution in the area of Nanjing Middle School I is similar to that in Eastern Guanghua Street, and the difference in urban spatial morphology results in the air temperature variance within local regions. For the Xuanwu Lake, the surface air temperature decreases outward from the land area in central Xuanwu Lake. The spatial variance of surface air temperature during the daytime is bigger than that in the nighttime due to the complex terrain in Toutuoling area.
